I am running a two node cluster for Exchange Server 2003. I tried to access OWA tonight and the site timed out. So I logged into the server to check the event log. I see the following error: "Exchange HTTP Virtual Server Instance 100 (GRENO-EXCHANGE): Failed to get the protocol IP address and port bindings from the metabase." I open Cluster Administrator and try to bring the resource online but it fails and provides the same event error as above. Firstly, what would have caused this? Secondly, how do I resolve this issue? Any help is appreciated. Thank you.
