Hi all

I have a new installed SBS2011 (with all Patches) with BE2012 SP1a and also all hotfixes
each time hen i log me on the DC then a lot of vss-errors are reported. (10 times)
The Credentials for BE is the Domain-Admin

error: vss event 13 the COM-Server with CLSID  {e579ab5f-1cc4-44b4-bed9-de0991ff0623}  an Name  "Coordinator" cant be started. [0x800401f0, CoInitialize isnt started.]

each event 13 is following another error vss 8193
on Start from "CoCreateInstance(CLSID_VSSCoordinator)" raised unexpected error . hr = 0x800401f0, CoInitialize wasnt star

I have been searched for this Error and also checked VSS-related items but all without Success.

Can someone help please ?

best Regards

Hi Jaydeep
Thaks for the answer - but this article does not solve my Problem.
(I have been checked this again and all was OK)

vss event 13 is the first one - maybe this should be the entrypoint.

i cannot understand why the vss errors occurs only when i logon to the DC.
The backupjob itself is working succesfull and without vss-errors.

Does that happne only with a perticular use account or very specific to your account. I am not much of a Windows expert but it is certainly worth posting this on the Microsoft forums as this does not seem to be connected with Backup Exec as such.

I have been restored the system to a earlier state just without backup exec. The problem was not there. After installing BE again i have the listed vss errors.

i have been found the solution.

O&O defrag server v16 was also installed on this system.
Each of them is working without any errors in the eventlog if the program is installed without the other one.

so i have removed defrag. (forever, i have spent so many hours)
