Re: Users not authenticating to local GC when hitting remote Exchange 2k3 server

Tech-Archive recommends: Repair Windows Errors & Optimize Windows Performance

The only versions of Outlook that use dsproxy are prior to Outlook XP if I
recall correctly.

If you have Outlook 2003 (or Outlook XP) deployed, it talks directly with a
GC for the Global Address List instead of having to talk to Exchange first
and have dsproxy refer it to a GC. In this case, it should talk to the
local DC as long as it is also a GC. in a single domain, there is no reason
not to make all DC's GC's.

How did you verify that the clients are actually talking to the central
office GC?
