Hi!

I have a winform that I host in IE, this winform communicates with a
webservice. On my development machine, this works perfectly, when I
access the IE page remotely, I get a System.Net.Webpermission failed
error when I try to access my webservice.

Now what I don't underatand is this: The webpage with the control
lies on server http://MyServer/mypage.html so I tried two things:
I created a codegroup that gives fulltrust to applications with url
evidelce http://MyServer/*

This did not work.

I then made sure that MyServer is part of my Local Intranet Zone
and edited the "Local Intranet" policy to give Full Trust to code run
from that zone.

Nothing

I suspect that I'm doing something wrong because the dll for the
winform is run from the local dell temp cache, but I don't know what
to do next, please help!

Thanks in advance for any replies,

Philipp Lenz
