Windows Forms controls hosted in IE

[Guest]

Hi I have a Windows Form control create in .Net 1.1.
We are having an interesting problem with the control and some interactions
with the server it is hosted on. We've recently upgraded one of our
Production Servers to Windows 2003 SP1. Our old server as well as our
development server are running Windows 2000 SP4.

After the upgrade we found that most users could not access the control on
the new production server. Accessing the old server or the development
server will allow the users to access the control. I don't believe it is any
code issue as the control still works using the old server. (I have strong
named the control and set the APTC bit so that should not play into this.)

The only thing that is different is the server is the update OS. Also,
there are people that actually can access the control on the new server and
their rights are not anything different than others. I've also tried just a
generic control (using the sample in MSDN) and that does not work for the
majority of our users as well.

Does anyone have any ideas what we can do?

maybe it related to the trust setting of the new server in the client's
computer?

I thought about that one too, but the new production server has taken the
name of the old server. All servers in question are in our local intranet.
I've played with changing the servers into the trusted sites zone as well as
changing the security level for the zones.
