Asp.net project on a remote server

Hi,
I've got an asp.net-project with codebehind. First I created it locally in
my Inetpub-directory. It worked well. Now the structure at my workingplace
is that we've got a development server on which all projects are stored. So
I moved my project to this server. I adapt my local virtual directory of my
IIS on my development computer to the new location of the project. I create
a new code group under .NET configuration->Runtime Security
Policy->Machine->Code Groups->All Code. The type of the group is URL. And it
points to: file://DEVSVR/D/SomeDir/ProjDir . I cleared all output dirs and
rebuild the solution. But when I try to debug my WebApp I get the error
message: Could Not Load Type 'MyNamespace.Global'.
What the **** am I doing wrong?

Thanks in Advance
