Older Outlook clients use the exchange server as a proxy to "access" the GAL provided by the DSPROXY component on the exchange server
Newer outlook clients (2000 and up) get a referral from the exchange server to a GC. These clients access the GAL on the GC through the Name Service Provider Interface (NSPI) on the GC. If I'm correct Exchange discovers (by default dynamically) the DCs/GCs by executing a LDAP query against the directory and not by using DNS as you think. So "tuning" DNS weights/priorities will not help with this. To realize what you you could statically define the DCs/GCs. As it says this is STATIC.

Main DC GC all FSMO roles server class Backup DC GC desktop class They both have the same weight and priority in the DNS. The main DC is a much more robust machine with RAID 1 for the OS and RAID 50 (or 05, I forget) for the page file and AD database (versus a desktop machine for the backup DC), so I would like to send the majority of request to it. Is there a reason that most request are going to the backup DC? Would adjusting the weight and/or priority even help? Ideas or suggestions? This would be the correct reference? http://www.microsoft.com/technet/prodtechnol/windowsserver2003/library/O perations/df86810b-9fc5-49b8-a704-d01c042cf460.mspx <http://www.microsoft.com/technet/prodtechnol/windowsserver2003/library/ Operations/df86810b-9fc5-49b8-a704-d01c042cf460.mspx> This e-mail and any attachment is for authorised use by the intended recipient(s) only.
