Service Unavailable...

Tuesday, 10 February 2009

Just had a call from one of my customers, he's getting 'Service Unavailable' when he hits Central Administration and the SSP Site, but the portal site running on port 80 is fine.

I've seen this a number of times, and almost everytime its the AppPool Identity account. Either the AD password for AppPool identity account wasn't set to Do Not Expire or for some reason the password needs to be re-entered again in IIS.

Firstly, check AD, make sure the account password hasn't expired, if so, then reset the password and ensure that the password is set not to expire.

Next Steps, check IIS:

Expand the Application Pool sub tree, and check if the Application Pool your failed web application is running in, is actually running! If not, right Click and Start.

If it is running ok, right click the Application Pool for the Web Application which is showing the Service Unavailable error, click Properties Identity

In the identity tab, re-apply the correct password for the service account, reconfirm, press Apply OK

Recycle the App Pool, or run iisreset /noforce and you should be good to go!

Note: If for some reason, you are running the Application Pool as Network Service and not a configurable username and password, then see this post :
