COM+ Connection point : Please Help!!!!

Hello ,

When Iam trying to use connections points in COM+ I am getting an error
Interface not supported when the server tries to make a call into the client
interface that was passed using the Advise() method. I did register the TLB
file using the TRegsvr delphi utility(i dont think i have to do it because
the i have the client and server on the same machine). Does COM+ support
Connection Points??

Please Let me know what iam missing...

Thanks a million!!!!
