Morro – A New Free Security software from Microsoft

Microsoft MorroMicrosoft has announced a plan to provide a free security software for users to compete with McAfee and Symantec.


According to this, Microsoft will stop selling the security software for personal computers and will allow users to download a free software to prevent viruses and spyware.

Microsoft intend to call this new security software Morro and it will appear in the first half of 2009, after Microsoft officially stopped providing Windows Live OneCare service to the users.

According to the statistics, Windows Live OneCare service after two years was only 2% in the security market. This is also a sign of Microsoft going down on this area compared with McAfee and Symantec.

Morro will be free to download and it is mainly for home users.

Difference between FAT,NTFS & NTFSVersion5

NTFS Version 5 features

Encryption is possible

We can enable Disk Quotas

File compression is possible

Sparse files

Indexing Service

NTFS change journal


In FAT file system we can apply only share level security. File level protection is not possible. In NTFS we can apply both share level as well as file level security

NTFS supports large partition sizes than FAT file systems

NTFS supports long file names than FAT file systems

Difference between 2000 & 2003

Application Server mode is introduced in windows 2003

Possible to configure stub zones in windows 2003 DNS

Volume shadow copy services is introduced

Windows 2003 gives an option to replicate DNS data b/w all DNS servers in forest or All DNS servers in the domain.

Difference between NT & 2000

NT SAM database is a flat database. Where as in windows 2000 active directory is a
hierarchical database.

In Windows NT only PDC is having writable copy of SAM database but the BDC is only read only database. In case of Windows 2000 both DC and ADC is having write copy of the database

Windows NT will not support FAT32 file system. Windows 2000 supports FAT32


Default authentication protocol in NT is NTLM (NT LAN manager). In windows 2000 default authentication protocol is Kerberos V5.

Windows 2000 depends and Integrated with DNS. NT user Netbios names

Active Directory can be backed up easily with System state data

The Difference Between POP3 and IMAP

There are two different protocols available to access e-mail: POP3 and IMAP. POP3 is useful when e-mail is checked from only one computer. IMAP is the better choice when you would like to check your mail from multiple computers, at work and home, for example. IMAP has the added benefit of accessing folders on the server, allowing you to organize your e-mail, and access it from anywhere. If you use Webmail, you should use IMAP on all of your e-mail clients. Use of a POP3 mail client in association with Webmail can cause errors in your inbox that will result in a temporary loss of access to your mail.

The Difference

POP3 works by reviewing the inbox on the mail server, and downloading the new messages to your computer. Clients can access their inboxes. no other folders on the server can be accessed. POP3 only handles retrieval of messages from a client's inbox. When using POP3, your mail is stored on your PC.

IMAP downloads the headers of the new messages on the server, then retrieves the message you want to read when you click on it. IMAP4 can be used to access multiple mailboxes and mailbox folders, and public folders, as well. When using IMAP, the mail is stored on the mail server. Unless you copy a message to a "Local Folder" the messages are never copied to your PC.

Webmail (a.k.a. Outlook Web Access) uses HTTP/HTTPS to provide Web browser-based access to clients' inboxes, their other mail folders and to public folders.

Scenarios of Use

POP3

  • You only check e-mail from one computer.

  • You want to remove your e-mail from the mail server.

IMAP

  • You check e-mail from multiple locations. at work and home

  • You use Webmail.

Tips Keep your Inbox small! This will speed up your e-mail retrieval. Checking the e-mail is directly dependent on how many e-mail messages are in your inbox on the mail server.

POP3

  • Set to remove mail from server after 30 days.

  • Don't check more frequently than every 15 minutes.

  • 75 MB is the maximum for POP3 users. POP'ing large mail boxes consumes excessive server resources.

IMAP

Do NOT check all folders for new messages! This slows your e-mail substantially.

  • Use "mail/" ( without the quotes ) as your IMAP folder directory.

  • You can set your client to download the mail and to remove the mail from the server, like a POP3 client.

  • Organize your mail into folders, and archive your older messages. This speeds e-mail retrieval by minimizing the number of messages in the inbox.

POP3

IMAP

Downloads messages to computer and deletes from server.

Downloads only header of the message. It retrieves the message only if you want to read.

Only inbox is accessible. No other folder on the server can be accessed.

Cab be used to access multiple mail box and mail box folders.

Mail is stored in PC

Mail is stored in server, unless you copy the message to local folder.

Choose if You only check e-mail from one computer


  • Choose if You check e-mail from multiple locations. at work and home


Choose if You want to remove your e-mail from the mail server

Choose if You use Webmail.

Files Used in the Windows Server 2003 Boot Process

File Location Boot Stage
Ntldr System partition root (CA) Preboot and boot
Boot.ini System partition root Boot
Bootsect.dos System partition root Boot (optional)
Ntdetect.com System partition root Boot
Ntbootdd.sys System partition root Boot (optional
Ntoskrnl.exe systemroot\System32 Kernel load
Hal.dll systemroot\System32 Kernel load
System systemroot\System32\Config Kernel initialization

Pre-boot sequence
Initialization of boot partition
Post – to determine amount of memory and hardware’s
Plug and play - enumeration and configuration of hardware devices
Bios -> locates boot device -> Loads and runs MBR

Boot sequence
Loads NTLDR -> Memory
gathers information about hardware and drivers
This haves four Phases
• Initial Boot Loader: Ntldr-> switches the microprocessor from real mode to
32-bit flat memory mode starts the appropriate
the minifile system drivers
(The minifile system drivers are inbuilt in Ntldr )
so that Ntldr can find and load Windows Server
2003 from partitions

• Operating System Selection: Ntldr reads the Boot.ini file and displays os
start menu. If no boot.ini presents Ntldr loads
Windows Server 2003 from the Windows
folder on the first partition of the first disk,
typically C:\Windows.

• Hardware Detection: Ntdetect.com and Ntoskrnl.exe perform hardware
detection.
Ntdetect.com collects a list of installed hardware
components and returns this list to Ntldr for later
inclusion in the registry under the
HKEY_LOCAL_MACHINE\HARDWARE key.

• Configuration Selection: the operating system loader process displays the
Hardware Profile/Configuration
Recovery Menu screen (if more that one hard
profile exists on the computer, the first
hardware profile is highlighted.)

Kernel Load

Ntoskrnl.exe -> Initialize and loads Windows 2003 kernel and device drivers ->
loads services.
• Loads Ntoskrnl.exe but does not initialize it.
• Loads the hardware abstraction layer file (Hal.dll).
• Loads the HKEY_LOCAL_MACHINE\SYSTEM registry key.
• Selects the control set required to initialize the computer.
• Loads device drivers with a value of 0x0 for the Start entry. These are typically
low-level hardware device drivers, such as those for a hard disk.

Kernel Initialization

the kernel initializes and takes control from Ntldr.
four tasks are performed:
• The Hardware key is created.
• The Clone control set is created.
• Device drivers are loaded and initialized.
• The Session Manager (smss.exe) is initialized.

The Session Manager
reads the
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager
registry key to find and initialize entries under Boot Execute. ( like chkdsk )
sets up the paging file (Pagefile.sys).
Loads winlogon.exe to start the authentication verification process.
winlogon.exe starts -> Local Security Authority Subsystem with their
. Print spooler.
supporting function libraries

Loads Screg.exe (Services Controller) which loads the rest of the devices and
services.
Boot .ini ARC Path conventions

Convention Description
multi(x) | scsi(x) -> Indicates hardware adapter or disk controller.
Scsi(x) -> indicate a SCSI controller on which SCSI BIOS is not enabled.
Multi(X) -> indicates All other hardware adapter or disk controllers
( (x) -> indicates the load order of the hardware adapter.
Disk(y) -> ID. For multi, this value is always (0).
Rdisk(z) -> A number that identifies the disk and starts with (0).
Partition(a) -> A number that identifies the partition. Partition numbers start with (1)


Boot.ini Switches

Switch Description
/basevideo Boots the computer using the standard VGA video driver.
/fastdetect Disables serial mouse detection. Without a port specification, this
Switch disables peripheral detection on all COM ports. By default,
this switch is included in every entry in the Boot.ini file.
/maxmem:n Specifies the amount of RAM that the operating system should use.
/noguiboot Boots the computer without displaying the graphical boot status
screen.
/sos Displays the device driver names as they are loading.

Advanced Boot Options

Safe Mode, loads only basic files and drivers that are required to support the
operating system

Safe Mode With Networking, -> safe mode + the drivers and services required to enable
network access

Safe Mode With Command Prompt -> after safe mode, it displays a command prompt.

• Enable Boot Logging -> logs the loading and initialization of drivers and services in
the ntbtlog.txt file, which is located in the windir folder and
can be used for troubleshooting boot problems.
• Enable VGA Mode -> starts Windows Server 2003 with a basic VGA driver.

• Last Known Good Configuration-> Starts Windows using the registry information that
windows saved after the last successful startup.

( After a logon, the system automatically copies the Clone control set to the
LastKnownGood control set making the current control set the Last Known
Good Configuration )

The Recovery Console
The Recovery Console is a command-line interface that can be used to perform a variety of troubleshooting and recovery tasks on the local computer. These tasks include:
• Starting and stopping services;
• Reading and writing data on a local drive; and
• Formatting hard disks.

Basic disk – can Four primary partition but only one extended partition
Dynamic disk -- five types simple volumes;
> default volume type on a dynamic disk.
> no fault tolerance.

spanned volumes;
> contain disk space from up to 32 physical disks.
> enables to group different disks of the same or different sizes
and access them as a single disk.
> provide 100 percent drive utilization
> No fault tolerance.

striped volumes;
mirrored volumes;
striped volumes with parity disk ( Raid 3 )
striped volumes with parity. ( Raid 5 )

Converting basic -> dynamic no data loss
Dynamic -> basic incurs data loss.

Increase the Browsing and Downloading speed in Windows Vista

With windows Vista you have noticed the slow internet speed. The web browsing and downloading speed is very slow as compare to previous versions of windows. You can open the same sites in windows XP and server 2003 with the normal speed.

Follow the given steps to increase the Vista browsing speed:

First go to Advance tab in Internet Explorer and turn off the TLS (Transport Layer Security) encryption option. Here to fix problem with some secure pages turn on the SSL 2.0 (Secure Sockets Layer) feature and click Ok button to close it.

Follow the major fix for this problem:

In windows Vista, the TCP autotuning feature is enabled by default. Some web servers do not respond properly to this feature, so it appears that some sites open with very slow speed.

To use this feature, you will need to be logged into your computer with administrative rights.

First click on Start button and type CMD in Run option then press Enter.

At Command Prompt, type the following command and press enter.

netsh interface tcp set global autotuninglevel= disabled

This command will disable the TCP autotuning feature. Now close the command Prompt and restart your computer after any changes to go into effect.

You can easily restore these setting by typing the following command at Command Prompt.

netsh interface tcp set global autotuninglevel= normal

Now close the command Prompt and again restart your computer after any changes to go into effect.

Increasing The Life Of Hard Disk

Taking care of your hard disk is important because this is the place where all the data is stored and once the hard disk crashes, data in most cases is not recoverable. There are data recovery softwares and programs which recover data from crashed hard disks but that is not for normal computer users.

But why do hard disks crash and what can be done to prevent them from crashing?. At the same time how can a hard disk be made more efficient? Here are the answers.

Hard disks crash due to many reasons. Voltage fluctuations, physical impact, improper alignment and of course mechanical failure due to wear and tear of internal parts. Let us start one by one and get the answers to the above problems.

1. Voltage fluctuations or spikes as they are called can be prevented by using voltage stabilizers or spike guards. This will limit the damage to the hard disk to a great extent.2. Physical impact can be prevented by handling the hard disk carefully when installing/ re-installing. When installing the hard disk care should be taken to see that it sits perfectly horizontal and that it does not vibrate or shake once the computer is started.3. The natural wear and tear of parts can be limited by defragmenting your hard disk from time to time.But what is defragmentation?

All newly created files are stored in various places on the hard disk in a single cluster ( contiguous file ). But, as the number of files and programs increase, these files are not stored as one contiguous file but broken down and scattered in various places on the hard disk. In short files get fragmented. When these files are accessed by the user, the head on the hard disk moves to and fro to locate these fragments. These fragmented files puts lot of mechanical pressure on the internal parts of the hard disk. This leads to crashes.

To start disk defragmenter from the start menu, click the start button and follow this path (All Programs / Accessories / System Tools / Disk Defragmenter). A minimum of 15 percent free space on your disk is needed for disk defragmenter to run. The disk can also be defragmented automatically by using schedule task. This program can can be accessed via system tools.

4. Power management tool can also be used to enhance the life of hard disk. To access this program go to start / control panel / power options and set the parameters for various hardware devices.

5. Disk cleanup increases the efficiency of the hard disk. So delete unwanted files and programs regularly.

Follow the above rules to increase the life of you hard disk.

Know to Recover the corrupted files from Microsoft Excel

There is no need to use any third party software to manage these types of corrupted files, because Microsoft provides the built-in support in Excel to deal with these types of files in better ways. You can use the SYLK (Symbolic Link) format to restore the corrupted files in previous state.

First click on Start button, go to Program then click on Microsoft Excel to run the excel page.


Now go to File menu and click on Open option to open the corrupted file.

Now again go to File menu and click on Save As option to save the file as type SYLK. Click on Save button to continue.

Common symptoms of viruses

  • Occurrence of strange messages, symbols or images appear on your screen.
  • Strange things happen when you are doing routine work.
  • The computer makes strange noises at inappropriate times.
  • Files you know you saved are missing.
  • The operating system acts slow, doesn't come on or just isn't working as normal.
  • Files of executable extension such as .BAT, .EXE, .COM, .HLP, .DLL should never be accepted from others as they have the most potential to cause problems or be infected.
  • All computer users should delete any unsolicited emails. We now know due to recent attacks that the Worms have begun to use Microsoft Outlook's address book, so it will appear as if a friend has sent you an email. If you are not expecting an email or the file name is different from the one you are expecting, delete the email and its attachment.
    Electronic Mail text messages cannot in themselves contain viruses. The text portion of a message is just text, and if read, does not contain damaging system codes. If, however, you receive an email message with an attachment, be very careful. File attachments, if executed, CAN launch viruses

Trouble shooting a Printer in General

  • Make sure the printer has power and is on-line. If you are using a manual printer sharing device, make sure the switch is set to activate the correct printer.
  • Turn it off and on again to reinitialize any internal settings that may have gone astray.
  • Ensure that the tape that seals the cartridge ink port is removed prior to installing the cartridge.
  • Use the printer's own self-test, according to the manufacturer's recommendation. If it fails, you have verified that the problem is within the printer. If the print head is not moving at all, the transport motor may have failed.
  • If the printer that you are using is not set as the default printer in Windows or the printer driver is not installed, the printer may print garbled characters. You may also receive errors when you attempt to print from applications.
  • If the printer passes the self-test, try a test print using the Print Screen capability within DOS. If the Print Screen fails, you know the problem is in the relationship between the printer and the computer. Inspect the cable and the cable connections. Replacing the cable with a known good cable is worth trying since cables are so frequently the source of printer problems. Cables can fail with broken wires, loose or broken pins, or incorrect pin-outs.
  • If the printer is connected to the computer through an add-in device, remove the add-in device and connect the parallel cable to the printer and then directly to the port on the back of the computer. Some examples of add-in devices are: switchboxes, parallel port scanners, external disk drives, external tape drives, security lock keys, or external CD-ROM drives. Some add-in devices may interfere with proper communications with the printer. Try printing again. If the printer prints successfully, the cable may not have been connected properly, or the add-in device may have been interrupting communication with the printer.
  • If the combined length of the cables connecting the add-in device and the printer exceeds 10 feet, communication can also be disrupted. In addition, the software that controls some add-in devices may take control of the printer port interfering with any other device attempting to use the same port. In some cases, the software for the add-in device should be disabled or uninstalled. Remove any add-in devices and uninstall the software for those devices, then try printing again.
  • The message "out of paper" is sometimes erroneously reported when there is plenty of paper, and can indicate a physical problem with the printer.
  • If the printer port is not properly identified in CMOS, the printer may not function properly and you may receive errors when trying to print. Check your User’s Guide on how to enter CMOS. Once in the Setup utility, locate the LPT1 settings. The address setting for the LPT1 port should be 3BCh or 378h depending on what kind of video card you have. The IRQ setting for the port should be 7 and LPT1 should be enabled in order for the printer to print correctly.
  • If the Print Screen succeeds, the problem may be with your application or its configuration. For example, your application may be set up to direct output to a file instead of the printer, or you might be directing the output to the wrong communications port.
  • Try connecting a different printer to this computer or try connecting the printer to a different computer and print a test page. If this printer works when connected to another computer, there may be a problem with the port on your PC. If this printer does not work when connected to another computer, there may be a physical problem with the printer.

Know your Computer's BIOS & itsBeep Codes

When a computer is turned on, it goes through what is called a POST (power-on self test) routine. This is a short diagnostic procedure incorporated into the boot sequence by the BIOS manufacture for troubleshooting purposes.

Many times when there is an error in your boot sequence you will receive an on-screen error message. This error was printed by the video card. But, in some cases, the error is detected early in the boot process and the error cannot be received by the video card. The problem may even be caused by the video card or the monitor. This is why the need for beep codes came to be.

Below, you will find some common codes listed by manufacturer.
