SBS 2011 Exchange server disabled but RPC keeps looking for the Exchane Topology

We have migrated a client out to Hosted Exchange and disabled the inhouse exchange services. The event viewer keeps flagging and error Event 1 MSExchange autodiscover THe Microsoft Exchange Active Directory Topology Service on server localhost cannot be contacted via RPC error 0x6D9

Any ideas on how to clean this up?

I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Remove Exchange.

If you have migrated the client out to hosted Exchange, then why bother keep Exchange on the server. Disabling the services just stops Exchange responding to requests - the product is still there, the clients still see it in the domain.

Is it safe to uninstall the Exchange off the SBS 2011 server without causing any other damage?
Will SzymkowskiSenior Solution ArchitectCommented:
As Simon has stated you can safely remove Exchange if you have already migrated to a hosted solution.

Creating Active Directory Users from a Text File

If your organization has a need to mass-create AD user accounts, watch this video to see how its done without the need for scripting or other unnecessary complexities.

If you remove Exchange from an SBS server then it will lose some of the wizard functionality - but if you are using a hosted Environment then you have lost that anyway.

Ok but will this stop RPC looking for it?
David AtkinTechnical DirectorCommented:
Removing Exchange will remove the Exchange RPC service as well.  This will stop the error.  I would do this as a last resort though.

As Simon said, this will break some of the wizards in the SBS Console.  In addition, you will also get warnings when trying to add users in the SBS Console etc (As it tries to create an email account at the same time).  You may also get errors relating to the SBS Data Collector service because it will try and monitor exchange.

When we've done this in the past we have just disabled all of the Exchange Services.  I don't remember seeing any RPC errors afterwards but its been a while since I've done it.
