QueryInterface for interface xxx.xxx failed.

We receive the error as written in the subject of this post, where xxx.xxx
is like PrintBillClass.IPrintBillInterface. What we are doing is calling a
COM object from our .NET Web application.

Note: It works on the developer's machine, but does not work on our
production machine.

The developer's machine uses XP and the production machine uses
Win2000-Server. The machines appear to be up to date, have the proper
security rights, and similar environmental settings.

Can anyone steer me to an answer?

Hi Robert:

Is the COM object a third party object or something written in house?
Is everything properly registered with the COM object?
