Why you are installing SEP on Exchange server. This is not the right product for Exchange. USe mail security for Exchange.

Hi Ajit,

Thanks for your reply. Yes we are using Symantec mail security 6.5. I wrongly typed it. And we dont know why this mail security needs RPC locator service to function. Any idea?

The Remote Procedure Call (RPC) Locator system service manages the RPC name service database. When this service is turned on, RPC clients can locate RPC servers.

When a Microsoft Outlook connects to an Exchange server, the client first connects to the RPC endpoint mapper using the RPC Locator Service, hence it will be required.

Hi Dineshks,

Here is a Connect Forum should you have any SMSMSE and SMSDOM questions:

(This present forum is the correct place for any SEP and SAV questions.) 

If you mean "why does the SMSMSE service have a dependency on the services named EventLog,RPCLOCATOR,RPCSS,LanmanWorkstation,LanmanServer,LmHosts" that is by design - please do not alter it.  &: )

Hope this helps!!


With thanks and best regards,
