Operations error

I'm trying in ASP.NET web page load user accounts from active directory.
When I'm developing on local web server it works.
I'm using authentication mode=windows and identity impersonate=true
When I put page and DLL on server I get COMException. I try to run it on
Win2000 server and Win2003 server and I get the same results (COMException)

Can anyone help ?

That is all the code. Show "only" the code that is generating the error.

Turn on Basic Authentication on the server. It's a permissions issue.
Locally you are using NT Auth, but that doesn't work across computer
boundries.

Yes, you'll get the user popup.
