Hello everybody, We are encountering a problem related to RPC error that restarts the servers those do not have Windows server 2K3 SP1. And these are Exchange Cluster servers and some other oracle servers. I have attended the problem immediately and for the time being I have changed service recovery option to restart the services instead of restart the computer. But I think it is not a permanent solution. Event log is as follows: Event Type: Error Event Source: Service Control Manager Event Category: None Event ID: 7031 Date: 10/2/2005 Time: 1:38:25 PM User: N/A Computer: BLDHKEXCL22 Description: The Remote Procedure Call (RPC) service terminated unexpectedly. It has done this 1 time(s). The following corrective action will be taken in 60000 milliseconds: Reboot the machine. For more information, see Help and Support Center at http://go.microsoft.com/fwlink/events.asp. Would you please help me. Best Regards, Osman Mahmud ________________________________
