Exchange/Global Catalog priority
Posted on 2006-04-26
150 users connecting to stand-alone exchange servers & DC, GC in house (exchange 2003 sp2)
150 users connecting to clustered exchange servers & DC, GC via 45 meg DS3 connection to a remote data center (*NEW EXCHANGE ENVIRONMENT*) (exchange 2003 sp2)
I need to point the 1st 150 users to my inhouse GC and I need to point the other 150 users to my remote GC. I've read numerous articles and I've come to conclusion that I need to change the priority & weight SRV records in DNS to accomplish this. But this would force everyone to point to one or the other. Is there a way to configure this in Exchange? There is a Directory Access tab in ESM on the properties of my server but I'm not sure this will accomplish what I want to do.
The reason for this is because I want my clients(outlook) to point to the GC that is closest to where their respective exchange server resides.
Before installing new my exchange cluster I did not have a DC,GC at that datacenter and I had complaints of Outlook receving the "Requesting data from server.domain.com" message anytime they try to do anything in Outlook. As soon as I installed a DC and made it a GC in the remote data center, complaints dropped, although we still get a few. I've looked at multiple clients (Outlook) whose mailboxes reside at the remote datacenter and the GC they are connecting to is the one in-house...but many times it changes to the GC in the remote datacenter and when that happens, performance increases and they do not receive the "Requesting data..." message.
Please let me know if I haven't explained myself clearly.
