File or assembly name or one of its dependencies, was not found.

[jlea]

I'm receiving the error message shown below when I try to load an aspx file
(C# web application) on our server. The web application works fine if I
remove the reference to the dll so I know the application and IIS are both
ok. I ran depends on the dll and all referenced dlls are either in system32
or in the bin directory of the web application. I suspect it is some kind of
security issue.

Any help will be greatly appreciated.

The error you are getting is a code access security exception. This means the
assembly you are working with (your project) cannot access the other assembly
or the other assembly cannot access some software it needs to work.

You can edit the machine.config to open security policy (there is also a
tool for this). Better yet, you can adjust the security for your particular
project (noting that an executable that is distributed to clients needs to
have the same security).

For your global assemblies, you can put them in the Global Assembly cache
and erase most exceptions. Most likely the issue is the assemblies in
System32.

Thanks for the good info. Where in the .NET IDE or IIS do I adjust the
security for the project? Jon.

I forgot to mention that the server is Win2000. When I run the same web
application from an NT machine (using IE) to my XP-Pro machine (running IIS)
within the intranet, all is good.
