John, Thanks very much for the reply. Just prior to reading it, I recompiled the app with VS .Net 2003. After that, the error went away. I had initially compiled the app under VS .Net 2002 and it was fine until I installed VS .Net 2003. I run both versions on this workstation, which is also used as the web server.

If so, you might want to check the user account being used in com+ setup for this paticualar application. I am stretching out here, but maybe a com object is being called under an account that does not have wsproxy rights. Sorry I'm not more help than that.
