Problems running multiple instances of web app.

I'm trying to deploy my VB.NET application onto one of our servers for in house testing. I'm running into a problem where I can only run the program one time, future times the session data appears to be getting messed up.

I've noticed that I can run the application once from any computer on our intranet. If I go to the web server and end the aspnet_wp.exe process, then I can run it again somewhere else. Otherwise I seem to be getting steming from session data not being correct (null when it shouldn't be, I think).

Do I need to do anything special on the webserver to allow multiple session instances at once? Any ideas where I can start looking?

Webserver is Win2k running IIS 5, .NET Framework installed

Any ideas?

Thanks in advance,

Chris

What is your session timeout set to? By default it is 20 minutes, but it may have been accidently changed in the web.config file.
