Install issues with 7.0.2 on Windows 2003

Having some difficulty installing 7.0.2 on Windows 2003.

I initially upgraded a version someone had previously installed on my server.  Upgrade was fine except I couldn't configure the administrator password from the previous install.  All the tips calling the ChangePassword util didn't work.  

So I un-installed as there was nothing of value in the previous install.  Install completes fine but this is all I get in the logs when prompted to start set up with "Enter the Maintenance Authentication Token:" prompt.

Any ideas here?  I installed TeamCity on my dev pc running Windows7 without issue.  I have had no joy with this Server 2003 install.
