Resolution

You may attempt to follow the resolution found in Microsoft Article KB912023, but do consider the following before performing them.

1. Ensure that the server harddisk is in working condition. You may check this thru the storage controller (RAID controller) utility. The usual errors to look out for are faulty harddisk or controller batteries that needs to be replaced.
   
   
2. Ensure that your file system is intact by running a chkdsk. This is ensure that your file system does not contain errors.
   
   chkdsk {system drive} /f /r
   
   
3. Ensure that your operating system files are checked for consistency (Be prepared to insert Windows Server 2003 CD). This is important if item 1 and 2 above contains errors on the server.
   
   sfc /scannow
   
   
4. Delete local policy registry subkey (if present)
   
   HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\IPSec\Policy\Local
   
   
5. Rebuild local policy store by running the command
   
   regsvr32 polstore.dll
   
   
6. Attempt to start service and test network connectivity.
