Solution




Check  the writer status by running "vssadmin list writers" command in windows command prompt and the status of the same will not be stable.

To resolve this issue some dll's need to be registered and for that refer to the Microsoft kb article attached below:http://support.microsoft.com/kb/940032


After completing the registration of the DLL's open an command prompt and type: vssadmin list writer. If this does not resolve the issue then some registry changes need to be done. Before making any changes to registry export the following registry key:
 
Warning: Incorrect use of the Windows registry editor may prevent the operating system from functioning properly. Great care should be taken when making changes to a Windows registry. Registry modifications should only be carried-out by persons experienced in the use of the registry editor application. It is recommended that a complete backup of the registry and workstation be made prior to making any registry changes
 
Windows Registry Editor Version 5.00
 

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\EventSystem\{26c409cc-ae86-11d1-b616-00805fc79216}\EventClasses\{FAF53CC4-BD73-4E36-83F1-2B23F46E513E}-{00000000-0000-0000-0000-000000000000}-{00000000-0000-0000-0000-000000000000}]
"Active"=dword:00000001
"EventClassID"="{FAF53CC4-BD73-4E36-83F1-2B23F46E513E}"
"EventClassName"="VssEvent"
"OwnerSID"="S-1-5-21-409134539-1862324775-1683105847-500"
"TypeLib"="C:\\Documents and Settings\\Administrator\\EVENTCLS.DLL"
"AllowInprocActivation"=dword:ffffffff
"FireInParallel"=dword:00000000
"EventClassPartitionID"="{00000000-0000-0000-0000-000000000000}"
"EventClassApplicationID"="{00000000-0000-0000-0000-000000000000}"

Try registering the dll: EVENTCLS.DLL to resolve the above issue.

Using filemonitor determine whether VSSADMIN is looking for Eventcls.dll in C:\Documents and settings\Administrator when it is actually in C:\WINNT\system32.

Copy the file over to the C:\Documents and settings\Administrator folder and now the 'vssadmin list writers' command returns the list of writers.

Refer to Microsoft kb article: http://support.microsoft.com/kb/833167

Note: After running these commands if VSS service is tried to be started manually it may not be displayed in the command prompt by running "vssadmin list writers". Server needs to be rebooted and then do not try to manually start the vss service. It will automatically start when application tries to access vss.
