Service unavailable message in IIS

I have created a sample ASP.NET website and hosted it in IIS 6.0 . It is working fine , if the identity of the defalut app pool is "local system". But when i changed the identity with some other configurable user id then it is showing as "Service Unavailable".

The following message is found in the event viewver.

"The identity of application pool 'DefaultAppPool' is invalid, so the World Wide Web Publishing Service can not create a worker process to serve the application pool. Therefore, the application pool has been disabled."

Check Application Pools which assign Site on IIS, probably it is stopped.

FYI,

In a development environment you can use the default app pool to create your web applications.

In production environment you want to use lusrmgr.msc (Server 2008/R2/7 Ultimate and Pro) to create new users (and their credentials) on the machine and assign the users to the right group (IIS_IUSRS).

Also once you have created the user, you will want to give it access to your data source back-end (if sql is running on the same machine and using windows authentication to access SQL).

The user identity you use needs to have fairly significant rights to operate. At a minimum the user needs to have read/execute permission on the root directory of the folder. This user should also have read/write/execute permission on the Temporary Asp.Net Files folder located within the %SystemRoot%/Microsoft.Net/Framework/ folder.

Message is self-explanatory. The selected user id isn't valid - probably due to insufficient privaledges to run the service.

Either the credentials provided for the user is not valid, or the user does not have the needed permissions.

I believe there is a security group on the machine called IIS_WPG that is created when Asp.net is installed, add the user to this group, it should give them the needed permissions.
