Activating 2003 Server x64

Setup a 2003 x64 server from my MSDN subscriprion.

All works fine but I'm unable to activate over the internet:

 Error 32777 – Unable to establish connection with the activation server

Tried phone activation - (888) 352 7140 - but she won't deal

with unsupported OS's.

Is there a way around this?

The MSDN subscription was through Volume Licensing.

Thanks

Gary
