We have a Web Service written in C# that accesses an ATL service via DCOM.
This all works great when both are on the same machine.

When I move to a two server scenario, I get an Access Denied error.

What is interesting is that I am able to get the Class Factory and then
create an instance of a COM interface. But I get the Access Denied error
when I then try and QueryInterface to another interface.

This all worked great under .NET 1.0. Has something changed in 1.1?

Thanks,

cl.
