Issues with old Global Catalog

HI there

In the last few months I have added 2 new DC's (Windows 2003 x64 SP2) All running fine. I moved the roles successfully off my old WIndows 2000 DC that had all the roles amd made them both GC's. I demoted that win2k DC and took it offline about 3 months ago.

I have one old WIndows 2000 DC that was a GC thats all. Obvioulsy I have to uncheck GC in AD sites & services before I demote this. However when I do this all my outlook clients lose ability to send mail and the Address list disappears.

I have seen articles which manually tell the clients to use a specific GC with a reg hack such as

http://support.microsoft.com/?id=319206

But It seems crazy that I have to do this on 100 clients, this old server is just a waste of electricity.

Anyone have any ideas of how I can get my clients to talk to the New DC's that are GC's ?

Thanks

You might have to change the GC in Exchange. I assume you are on Exchange 2003. Open ESM nad drill down to your exchange server. Right click and get properties. Click on the Directory Access Tab and show Global Catalog Servers. There will be your list. Also, make sure you update your Recipient Update Services to point to the appropriate Server.

Also make sure that after you checked the new servers to be a GC, that you rebooted them.

I see, it has the 2 new and the old win2k GC listed, should I switch to manual discovery and remove the win2k box?

Or would I be better on the weekend when no one is logged in, to remove GC from that DC and reboot the exchange box so it auto discovers only the correct boxes.

Obviously the outlook clients can't dynamically change their GC selection once they have been logged in.

You could set it to manual. The only problem with that is that if you ever add another GC, you have to remember to set it in Exchange again.
