Can't Change Operations Mode Exchange 2003 - Can't find my old 5.5 Server anywhere

Posted on 2009-03-31
Last Modified: 2012-06-27
I'm trying to update our Exchange 2003 Server to Native mode so we can upgrade. It blanked out which would assume our old 5.5 Server is hiding somewhere. The 5.5 Server itself has long gone. I've read through loads of posts and have tried the following,

MS 272314 - Tried to connect to Exchange Admistrator. I get the C10312c8 error when i click browse and the DS_E_COMMUNICATIONS_PROBLEM when i type the name of the server.

I have been into ADSI edit but the server isn't listed there.

I've been into ADC Tool to make sure it was removed at that point & I can't see the server here.

Any help would be great as I'm going round the houses with this one. We've got a straight forward Single Domain, single Forest with just one Exchange server.

Go to system Manager->Tools->Site Replication service

Do you have a connector that maps to you exchange 5.x system ??

If so delete it

If you don't have 5.5 you shouldn't have site replication service at all

delete the connector remove the site replication service

We have only one server. When we first upgraded many moons ago we had a failure and had to rebuild another server and migrate all the users over to a second exchange 2003 server. That server then got removed. The service is the SRS is the same name as the current exchange server and not the 5.5 or the failed 2003 server. Is that correct to delete it still?

Solved. Many Thanks. Problem was that the legacy server was given the same name as the current after a server failure.
Thanks for all your help!!
