ASP Site error! Pool identity error

[madvic]

hi i am using plesk 7.6 windows. when i change app pool identity to "predefined" there's no problem but when i change it to configurable i get "Service Unavailable" error. i accidently deleted IWAM_plesk(default) user. what can i do? i have reinstalled plesk before i deleted the user but nothing changed?

i've solved the problem by changing the App pool to "defaultapppool" and the web site is running superb
