Disable IPV6 in Windows Server 2008

Unlike Windows XP and Windows Server 2003, IPv6 in Windows Vista and Windows Server 2008 cannot be uninstalled. However, you can disable IPv6 in Windows Vista and Windows Server 2008 by doing one of the following:

• In the Network Connections folder, obtain properties on all of your connections and adapters and clear the check box next to the Internet Protocol version 6 (TCP/IPv6) component in the list under This connection uses the following items.

This method disables IPv6 on your LAN interfaces and connections, but does not disable IPv6 on tunnel interfaces or the IPv6 loopback interface.

• Add the following registry value (DWORD type) set to 0xFF:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip6\Parameters\DisabledComponents

This method disables IPv6 on all your LAN interfaces, connections, and tunnel interfaces but does not disable the IPv6 loopback interface. You must restart the computer for this registry value to take effect.

Manually move SEP 11 client to another parent server

1. Get the new Sylink.xml from the appropriate folder in the new parent server
- On the computer that runs Symantec Endpoint Protection Manager, go to:
"C:\Program Files\Symantec\Symantec Endpoint Protection Manager\data\outbox\agent\"
You will see folders with 32-character alphanumeric names, each representing a client group.
Find the folder corresponding to the first 4 unique Alpha-Numerals noted for the 'Policy Serial Number'.

2. On the client computer:
Start --> run --> smc -stop ( It will stop the service)

3. Copy Sylink.xml file from Step 1 and replace under c:\program files\Symantec\Symantec end point protection.

4. Start --> run --> smc -start (it will start the service)

5. Verify the client has been moved to the Default group in the SEPM console and move to the appropriate group if necessary.

What to do when CHKDSK keeps finding errors

Confirm that your hard disk or file system is not damaged.

Start your computer from the Windows XP CD-ROM, load Microsoft Recovery Console, and then use the Chkdsk command-line utility. This may solve your problem.

Important We recommend that advanced users or administrators use the Recovery Console. You have to know the Administrator's password to use the Recovery Console.

For additional information about how to check and repair a damaged hard disk by using Chkdsk, see the "Using the Recovery Console" and "Using the Recovery Console command prompt" sections in the following article:
307654 (http://support.microsoft.com/kb/307654/ ) How to install and use the Recovery Console in Windows XP
Note If the Chkdsk command reports that it cannot gain access to your hard disk, you may have a hardware failure. Examine all cable connections and any jumper settings on your drive. For more assistance, contact a computer repair professional or the manufacturer of your computer.

If the Chkdsk command reports that it cannot fix all hard disk problems, your file system or Master Boot Record (MBR) may be damaged or no longer accessible. Try appropriate Recovery Console commands such as Fixmbr and Fixboot, contact a data recovery service, or repartition and reformat your hard disk.

Important For more help, contact your computer manufacturer or a Microsoft Product Support Services professional.

Allow only qualified personnel to repair your computer. Computer repair that is performed by non-qualified personnel may nullify your computer's warranty.

If you repartition and reformat your hard disk, you lose all the information on the disk.
