I have the following setup.
EXCH 2007 with 2 HUB-CAS server and 2 mailbox server.
For intern, we use a network load balancer (NLB) , which is also installed on both HUB-CAS servers.
But for some reason, on one HUB-CAS server, the APP-POOLS in IIS are stopped.
Then we have problems with OWA, OoO and Autodiscover.
Can you help me to find out why always the APP-POOLs on the same HUB-CAS gonna stop ?
