WSUS: SRV 2008 R2, Code 8007EE2

Server 2008 R2

Error CDEO 8007EE2, Windows Update encountered an unknown error

Try the easy things first:

wuauclt.exe /resetauthorization

wuauclt.exe /reportnow

wuauclt.exe /reportnow /detectnow

wuauclt.exe /UpdateNow

Reboot

If not solved try:

net stop wuauserv
net stop bits

2. I then went to the following folders and deleted everything inside it.

c:\windows\softwaredistribution\Downloads – delete all files in it
c:\windows\softwaredistribution\DataStore – delete DataStore.edb
c:\windows\softwaredistribution\Datastore\Logs – delete all files in it
c:\windows\softwaredistribution\PostRebootEventCache – delete all files in it

net start wuauserv
net start bits

Reboot the Server

If this does not fix the Error reinstall the WSUS-Client. Install the latest Windows Update client for your OS from:

At the end this should look like this AFTER you check "Check for Updates"
