AD Access problems


Two or tree times a day I have this event :

Event Type:      Error
Event Source:      MSExchange ADAccess
Event Category:      General
Event ID:      2152
Date:            1/7/2008
Time:            1:27:56 AM
User:            N/A
Computer:      EXCHANGE64
Process MSExchangeTransportLogSearch.exe (PID=1760). An remote procedure call (RPC) request to the Microsoft Exchange Active Directory Topology service failed with error 1753 (Error 6d9 from HrGetServersForRole). Make sure that the Remote Procedure Call (RPC) service is running. In addition, make sure that the network ports that are used by RPC are not blocked by a firewall.

It returning to normal after 10 or 15 minutes.

When I get this error my Exchange is becoming unusable for the Outlook users.

Do you have an idea to fix this issu?

Thanks for the help

I found the problem. I had my Linux router in the DNS server on the network card. I have removed it and now everything is OK.
