  • Hi Devsri

    Have you tried updating to SP2 at all? Are all your windows updates installed on the box?

    Are their any other errors logged in event viewer?

    Lastly do you have AV running on the exchange server and are all exclusions set?

  • Hi,

    we have set all the exclusions in our AV  and using SP1.

    the below appln error event 1000 was logged during the time

    Faulting module name: ntdll.dll, version: 6.1.7601.17725, time stamp: 0x4ec4aa8e

  • Have you checked the hardware in the machine? Memory/Disk/cpu would be your first step. I have seen exchange boxes fail/lock up when all resources have been overutilized, this looks like the machine fails or is trying to restart the rpc service and for some reason in services the service is set to restart the machine when the rpc service fails to start up. Check on those and if you have any other event log errors or warnings please post more...

    Hi,

    The support for Exchange 2010 SP1 will end on 1/8/2013 and since you are very much behind an updated patch level, I would strongly suggest that you patch your server. It might very well solve your problem since.

    Microsoft Exchange Server 2010 Service Pack 2 (SP2)

    Update Rollup 5-v2 for Exchange Server 2010 Service Pack 2 (KB2785908)

  • Hi Devi,

    I also suggest you install the latest service pack and rollup first in order to avoid some known issue.

    Did you install it successfully?
