Server App Unavailable Error

[Dman]

I have a web service that I can access from a client machine as long as that web service is on the machine I delevoped it on. I created a virtual directory on our server's (Small Business Server 2000) internet information server and put all of the web service's files in the inetpub/wwwroot folder. However, when I try to access the web service while it's on the server I get an error that says that the server application is unavailable.

The error says to reference the system logs for a detailed description of the failure. When looking at the Event Viewer on the server the following error shows up:

"aspnet_wp.exe could not be launched because the username and/or password supplied in the processModel section of the config file are invalid"

I'm new to asp.net. Does anyone have any insight as to why this is happening?

Thanks in advance.
