We recently moved our webserver from one hosting collocation to another and everything seemed to come online nicely. Once I got back home, I got a call from a customer saying that their site had gone back down. Checked the server and it was still alive and kickin', only their site was unavailable. I logged in and checked the Event Viewer and found this error with no other messages
A worker process with process id of '2900' serving application pool 'Professional Education Services' was shutdown due to inactivity. Application Pool timeout configuration was set to 20 minutes. A new worker process will be started when needed.
OK, no big deal right? Once it's needed it should spool back up, right? Well, I thought so, but it's not. Any ideas? Is there any configuration that may have to be updated from the move. Our IP addresses all changed and I configured the host headers and DNS records, is there something in IIS that I'm missing :(
