Symptoms

Login to PPA Control Panel -> Webistes -> Website->'Open in Control Panel' -> Websites -> Advanced Operations -> ASP.NET Settings, I get error:

    ERROR: PleskUtilException

    Invalid namespace 

Cause

WMI is broken and should be repaired on Service Windows Node.

Resolution

1. Create a wmi_repair.cmd file with the following content:

   net stop winmgmt
   pause
   c:
   cd c:\windows\system32\wbem
   rd /S /Q repository
   regsvr32 /s %systemroot%\system32\scecli.dll
   regsvr32 /s %systemroot%\system32\userenv.dll
   mofcomp cimwin32.mof
   mofcomp cimwin32.mfl
   mofcomp rsop.mof
   mofcomp rsop.mfl
   for /f %%s in ('dir /b /s *.dll') do regsvr32 /s %%s
   for /f %%s in ('dir /b *.mof') do mofcomp %%s
   for /f %%s in ('dir /b *.mfl') do mofcomp %%s
   net start winmgmt
   

2. Run the script to repair WMI.
