I've posted this before but didn't really get an answer. I'm trying again because I really need help with this. It has happened 3 times within the past 2 weeks. We seem to be having an issue with OWA. Sometimes the IIS Admin and WWW Publishing services will "terminate unexpectedly". Although they also seem to restart themselves. However, none of my users can access OWA until I restart the server. Has this happened to anyone? Any ideas? It's an Exchange 5.5 server, sp4 on W2k, sp3 box.
