We use an image program that utilises vistas vss on about a hundred machines. Lately, it stopped working on two machines and that's because of vss having a problem. The error message is documented here http://technet.microsoft.com/en-us/library/cc734235%28WS.10%29.aspx
The recommended solution however is to contact the vendor of the backup software - that vendor however just tells me that vss is broken.
I am looking for a way to repair it but I can only find solutions for xp.
I have attached a procmon logfile, filtered for vss.exe, rename it to logfile.pml and the vss service registry keys.
Update: while starting this thread, I have solved it for one of them: after re-enabling system restore, vss is working again. On the other computer however this has not helped
