Application Pool Stopped (Automatically Stops)

I am going to put this one up because it has popped up twice now on local vista boxes with WSS installed (I keep forgetting), and hope that it helps some other person out there save time when troubleshooting.

If your application pool(s) are automatically stopping every time you start them and visit a SharePoint site (or any website) then it might be because the application pool identity password has changed.

When this happens it results in a page result like this: (Since the application pool is stopped.)

Service Unavailable HTTP Error 503. The service is unavailable. (This is on a vista box with IIS 7 etc)

An easy way to check/resolve this is to just go to the identity setting of your application pool and re-add the password (as it was) to see if this resolves the issue. (Or in this case add the new password).

In theory your application pool identities password should never change since this is an account designed for this use (in many cases) but when I setup my local vista boxes I normally set it up to use my own identity which has a password that changes so this was something I had to troubleshoot when it came up.

Who knows maybe someone else has a reason for using an account which has it’s password changed periodically. If so then this is going to be something that you should take into account in your planning for whenever that password does cycle.

Hope this helps someone,
Richard Harbridge

    Thanks…This helped me too. I am a domain user in a development environment and the company’s policy is to change passwords every 2 weeks, so that’s what I hit when I changed my password.
