prubin Posted December 3, 2009 Report Share Posted December 3, 2009 I had a backup that had been working for months. Suddenly it always hangs on preparing for a volume shadow copy on 1 specific station. Tech support told me that VSS (volume shadow copy) was not working they method to fix is reinstall windows. Given this information I found this page: http://www.itnewsgroups.net/group/microsoft.public.windows.server.general/topic8512.aspx It does not give a clear statement, but using this I went from no writers when running: vssadmin list writers to 11 writers and the backups going fine. Open a command prompt and change directories to \windows\system32 (this is important when you begin registering the dlls): net stop vss Then register the following dlls and services (be sure you're still in the windows\system32 directory at your command prompt): regsvr32 ole32.dll regsvr32 vss_ps.dll Vssvc /Register regsvr32 /i swprv.dll rRegsvr32 /i eventcls.dll regsvr32 es.dll regsvr32 stdprov.dll regsvr32 vssui.dll regsvr32 msxml.dll regsvr32 msxml3.dll regsvr32 msxml4.dll If you then run these you should get lists of providers and writers: vssadmin list providers vssadmin list writers Quote Link to comment Share on other sites More sharing options...
