I recently needed to reset the configuration, metadata, and content of a Wsus server. I wanted to wipe the entire slate clean, and start again. This is the process I followed:
Stopped the WSUS service using the following PowerShell command:
Uninstall-WindowsFeature -Name UpdateServices-Services, UpdateServices-DB -IncludeManagementTools
Rebooted the server.
Deleted the WSUS content folder:
rmdir /s C:\WSUS\WSUSContent
Deleted the WSUS binaries:
mdir /s C:\Program Files\Update Services
Connected to the local SQL Express 2008 instance:
sqlcmd -E -S localhost\WSUS
Listed the databases:
exec sp_databases; go
Dropped the WSUS database:
drop database [SUSDB]; go
Listed the databases again to confirm SUSDB was removed, then switched back to PowerShell and reinstalled WSUS:
Add-WindowsFeature -Name UpdateServices-Services, UpdateServices-DB -IncludeManagementTools
At this point, the C:\Program Files\Update Services\Tools folder was missing. Strange. Ran the system file checker to scan the server for errors:
Following the completion of the scan, the Tools directory was present.
Ran the following PowerShell commands to complete the configuration of WSUS:
$WSUSContentFolder = "C:\WSUS" $WSUSUtil = "$Env:ProgramFiles\Update Services\Tools\WsusUtil.exe" $WSUSUtilArgs = "POSTINSTALL CONTENT_DIR=$WSUSContentFolder SQL_INSTANCE_NAME=`"$env:computername\WSUS`"" Start-Process -FilePath $WSUSUtil -ArgumentList $WSUSUtilArgs -NoNewWindow -Wait
At this point I was able to launch the WSUS Administration Console and commence the configuration of WSUS.
