I've got this server, and we've been having VSS issues for quite awhile. We've tried every form of re-registering the VSS drivers we can think of.

  • NTbackup won't run a system state backup
  • vssadmin list writers doesn't list anything.
  • We're getting VSS error 12302 in the event log.

Has anyone ran into a situation like this before? We're thinking the next step, if possible, is a complete reinstall of the VSS.


General Info

Role: Domain Controller

OS: Windows Small Business Server 2003

Version: Small Business Server Service Pack 2 Build 3790


MS SQL Server 2005

Microsoft Exchange Server 2003 SP1

  • What other software is running on the server? I had similar issues on a server with Truecrypt encrypting a portable HDD attached to it. Carbonite has also caused problems for me.
