First time ever I ran into this issue but today I had one server that refused to install SP1. It failed with the error “RPC_S_CALL_FAILED(0x800706be)”. The solution is quite simple if you know it. Download and install the Windows System Update readiness tool. Afterwards try to install SP1 again and it works 🙂

In case it still doesn’t, have a look at the log file and see if there are still corrupt or missing files. You can always copy them from another server. The logfile is located under “C:WindowsLogsCBSCheckSUR.log”
