I have an NT 4.0 server that i just inherited. It has Exchange 5.5 and OWA on it.
Peridoically the OWA times out. If I reboot the server, everything works fine for about 2 to 2.5 hours.
After that, OWA times out again untilt he next reboot. Can't stop and start IIS either eithout rebooting.
Stops, but won't restart unless reboot occurs.
