Have you ever received an invalid application pool identity error when you know you have entered in the username and password correctly? In some instances the username and password is indeed incorrect, but in some cases the following error is found in the eventlog:
“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.”
In this case the application pool identity is in fact correct, but the user being used is not part of the IIS_WPG on the relevant server. Only users in this group may start worker processes. Simply add the user and recycle the application pool.
Badaboomtish!
This saved me hours of frustration. Thank you
Thanks a million.
Thanks for this.
