I have a server 2008 R2 x64 that perform as domain controller.
I have encountered with a problem that I can't update the server using the "windows update" service.
I get this error "code 8000FFFF windows update encountered an unknown error".
I have a WSUS in my network, but the DC wasn't a part of the pc's that get updates from it.
I then include the DC to the WSUS computer list, but still i get this error.
Please notify that the error is displaying only at the end of the process, it seems that the updates are installed but then I get the error.
