I am an MSDN subscriber, downloaded Vista from MSDN and attempting to
activate using Vista Business product key. Everything else on the
system seems to work fine.

Hello Roland,
Is the RPC server running? There is a dependancy on this working.
Can you boot to the DVD and run the repair process and report if this
changes anything?
Open an elevated CMD prompt and run sfc /scannow as well just to be safe

I am having this same issue. Ran repair and just finished elevated sfc ...
did get an error with a nice HUGE log file.
Near the VERY bottom, there is an error with SLSVC.EXE
