I ran into this last week
I was getting VSS errors, So After my usually things I resorted to Try and Reconfigure Backups
However I got Error “The wizard cannot retrieve backup settings”
So I found this KB
But it didn’t help at all!
Writing to Microsoft Shawn Song, Supplied this as an answer I’m posting it here for others to gain from it.
(And this worked)
a. register the dlls with the following command:
Open a DOS Window (Run As Administrator)
Paste the below in it, (Or run each line I just like to copy and paste it does the same thing.)
cd /d %windir%\system32
net stop vss
net stop swprv
regsvr32 /i swprv.dll
regsvr32 /i eventcls.dll
(You have to select OK for eachone>)
Then do this.
Make sure the following key is correct:
Then right-click it select Permissions.
1. Make sure these object listed in the Permissions dialog box.
CREATOR OWNER = Special permissions
SYSTEM = FULL CONTORL
Administrators (domain\administrators) = FULL CONTROL
Users (domain\Users) = Read & Special permissions
EventSystem = Read & Special permissions
2. Then, go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\VSS\VSSAccessControl, below sub-key list here.
NT AUTHORITY\LOCAL SERVICE [REG_DWORD] 1 (0x00000001)
NT AUTHORITY\NETWORK SERVICE [REG_DWORD] 1 (0x00000001)
NT Authority\NetworkService [REG_DWORD] 1 (0x00000001)
3. If there are other keys listed except above three, please export whole VSSAccessControl key to a *.reg file then remove all key except above three keys. If the value of above three keys isn’t 1, please change to 1.
c. Restart the server and check if the issue persists.
