Exchange 2010 wont recognise Domain Controllers

I have been involved in a server migration from SBS 2003 to Windows Server 2008 r2, Exchnage 2003 to Exchange 2010

Everything seemed to be going well until we got to the stage of turning off the SBS server.

It seems for some reason that its not recognising itself as a domain controller. There should be a 2nd server in that attachment image called fileserver.

I have not been able to get it to show up at all. so everytime I turn off the SBS server I am unable to access the exchange console and mail stops working

Any ideas?

Have you removed Exchange from the SBS server?
If not then that will cause problems. When Exchange is installed on a DC, it is the ONLY DC that all Exchange servers will use. You need to remove Exchange from that DC and ensure that you have another DC with the global catalog role enabled. Once you have done so then you can restart the Exchange services on the new server and it will pick up other domain controllers.

- Rancy, the new server is Server 2008 r2 sp1

- Sembee2, No I have not removed it from the old server yet, I was hoping to make sure it was working correctly on the new one first. I am a bit cautious about removing it from the SBS server in case I do and the new one still doesn't work. I have another DC with GC already.

Is Your AD Toolbox Looking More Like a Toybox?

Managing Active Directory can get complicated.  Often, the native tools for managing AD are just not up to the task.  The largest Active Directory installations in the world have relied on one tool to manage their day-to-day administration tasks: Hyena. Start your trial today.

You are stuck then - as until you remove Exchange from the old server, the other server will not use any other domain controller.

Process MSEXCHANGEADTOPOLOGYSERVICE.EXE (PID=1944). Exchange Active Directory Provider has discovered the following servers with the following characteristics:
 (Server name | Roles | Enabled | Reachability | Synchronized | GC capable | PDC | SACL right | Critical Data | Netlogon | OS Version)
In-site:
main.*****.local      CDG 1 7 7 1 0 1 1 7 1
FILESERVER.*****.local      CDG 1 0 0 1 0 0 0 0 0
DC1.*****.local      CDG 1 7 7 1 0 1 1 0 1
 Out-of-site:

Fileserver is the new exchange server
main is the old exchange server

It has found it, but it will not use it for the reasons I have given above.

You installed Exchange 2010 on to a domain controller?

Yes it was, as it will be taking over as the only server on site, the 3rd is just a temp domain controller that wont be staying

Seems Netlogon service isnt started on DC1. Also if this is the DC\GC it has to advertise as one
