Web Service dll question

[Worrow]

I have a web serive which handling some db works between the client and server. It uses one dll inside the Bin folder. Later I added another dll which handling zip file. The name of that dll is Interop.Shell32.dll. Then I tried to run the web service but I got an Error page instead! It says something about Configuration Error and Access is denied. I tried the same web serivce (with new dll)again on another machine and it works just fine.

What kind of error is it? Is this has anything to do with Interop.Shell32.dll(the dll I added)?

Thanks in adnvance.

Most likely yes. If it was working fine before and then not after. This is fundamental troubleshooting logic. I suspect that it is some type of permissions issue. Depending on the shell command you are trying to execute, the account the Web Service is running under (ASPNET) may not have the required permissions on the problematic box.
