I have a 2008 R2 server that used as a Domain Controller,
Until a week ago the server use to be in a WSUS servers group that receive updates from it.
I have notice that the server 2008 R2 SP1 didn't installed on the server (error 8007000d).
I have tried several things to solve this, including:
1. Toke the dc server out from the wsus server.
2. Cleaning the "software distribution" folder that holds the downloaded and yet installed updates from the WSUS.
3. Manually installing the SP1 (got error 80070490d).
4. Run the sfc /scannow command to see if the system files are corrupted (they are fine).
I have read in a post from Microsoft about this error :
It says that the solution is to perform an in place upgrade,
I don't know if this step is necessary.
Waiting for your advices.
