Question : Com+ Catalog Error, more security related errors

Hello Experts,

after a system restart, my colleague informed me that cannot start the VSS service.

Doing some troubleshooting i found out that i cannot open Com+ Application catalog and i am receiving error:


"Com+ Catalog Error. You do not have permission to perform requested action.If security is enabled on system application of the target computer make sure you are included into appropriate roles."

after doing more searches on the system i found out that i also cannot open/view:

gpresult :  ERROR: Logon failure: unknown user name or bad password.

RSOP.msc  returns, YOu do not have permission to perform this operation.

and i cannot view service dependencies ( Win32: Access denied) or network connection proprieties ( nothing is in there)

i am using a domain account which is working fine on other servers from the same location. I tried also with local admin, other admin accounts and still i am receiving the same errors.


Server is Windows 2003 and some security setting was applied or some security setting is corrupted.

maybe some security rights were removed but which ones?


Thanks for help!

Try restoring registry settings ( remove everyone and add power users to the root of HKCR)
verify after the registry change if you can access DCOM and WMI.
re-register VSS and test with system backup
