Configuring Com+...

I have tried upgrading to windows 2000 pro.
Whilst upgrading the system states "installing components"
Status configuring COM+...
At this point the blue bar does not move foward and stays
at this point.

Does any one have any suggestions what the problem can be.
I have tried rebooting but the setup is now in a loop and
asks for the setup disk all the time.

Regards
Sunil
