I have a Windows Server 2008 Enterprise x64 that will not allow me to install SP2. When I try to install the SP, it eventually states that I must install SP1 first. SP1 is already installed. If I try to install the updates with Windows Updates, I get an error of 800B0100. This is with ANY of the updates I attempt and not just SP2.
This server is running Hyper-V in a cluster environment, but currently all the other virtual guests are on the other server in the cluster environment.
