>I got passed the 0 record count problem by testing the code in VB. The object seems to be created but hangs when the GetAllDepartments call is made under IIS.

You've got other issues to consider on a web-based application. I would suggest having your MTDLL return any errors that may be resulting by using COMRETURNERROR. If there are any ADO errors, be sure to include the NativeError property on the message string.

I don't suppose you left the (?) in your MTDLL? It may be that since you can't do any UI code it's stopping there.
