If you are having issues with a fresh install of 2008 Server (I was using R1 64 bit)...
I found that network issues can seriously hamper performance on this operating system.
This forum entry helped me enormously in disabling the network features that were
hampering performance, eventually found to be a DSL broadband access issue.
Apparently 2008 server R1 stability is very dependent upon network stability.
