Hi all The OWA 03 from our FrontEnd Server dies sometimes. The site shows me only the message "Service unavailiable". I see in the Systemlog many from the following errors: A process serving application pool 'ExchangeApplicationPool' suffered a fatal communication error with the World Wide Web Publishing Service. And at last the message: Application pool 'ExchangeApplicationPool' is being automatically disabled due to a series of failures in the process(es) serving that application pool. Because of that the service dies. When I restart the WWW Service the OWA works again until the next errors occurs. How can I fix that?
Hi, The problem was that the subnet which the server was in was not part of the corporate site. "AD site and services" was used to add the subnet to the corporate site. You mau try the following steps: 1. Make sure to add the correct IP and Mask for the subnet. 2. reboot the FE 3. Once that is done, wait for replication about 15 minutes Kind Regards, Yudhil.Faisal "Carma Trepp" wrote in message news:ehhVb%23ywFHA.1456@TK2MSFTNGP11.phx.gbl... > Hi all > > The OWA 03 from our FrontEnd Server dies sometimes.
