VSS ADMIN LIST NO WRITERS - VMWARE ESX 4 BACKUP

Problema dei backup VMWARE - BACKUPEXEC che falliscono con errore Event ID:12302 nell'event viewer di windows.

Volume Shadow Copy Service error: An internal inconsistency was detected in trying to contact shadow copy service writers. Please check to see that the Event Service and Volume Shadow Copy Service are operating properly.

Il comando "vssadmin list writers" non fà vedere writers attivi.

Il problema si risolve cambiando questa chiave di registro:

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\EventSystem\{26c409cc-ae86-11d1-b616-00805fc79216}\EventClasses\{FAF53CC4-BD73-4E36-83F1-2B23F46E513E}-{00000000-0000-0000-0000-000000000000}-{00000000-0000-0000-0000-000000000000}]
"OwnerSID"="S-1-5-21-2539932445-1752893067-3068508878-1003"
In
"OwnerSID"="S-1-5-18" (è il SID di dello user SYSTEM, lo si può trovare usando il comando "psgetsid" scaricabile da Internet)

ed riregistrando le dll relative ai servizi di vss:


cd /d %windir%\system32
Net stop vss
Net stop swprv
regsvr32 ole32.dll
regsvr32 oleaut32.dll
regsvr32 vss_ps.dll
vssvc /register
regsvr32 /i swprv.dll
regsvr32 /i eventcls.dll
regsvr32 es.dll
regsvr32 stdprov.dll
regsvr32 vssui.dll
regsvr32 msxml.dll
regsvr32 msxml3.dll
regsvr32 msxml4.dll

reboot del server !
