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.

CAUSE
By default, ASP.NET runs its worker process (Aspnet_wp.exe) with a weak account (the local machine account, which is named ASPNET) to provide a more secure environment. On a domain controller or on a backup domain controller, all user accounts are domain accounts and are not local machine accounts. Therefore, Aspnet_wp.exe fails to start because it cannot find a local account named "localmachinename\ASPNET". To provide a valid user account on the domain controller, you must specify an explicit account in the <processModel> section of the Machine.config file, or you must use the SYSTEM account.
