I am running OCS in our DMZ - I have an Exchange 2007 environment, and ISA 2006 also. The error i am getting is as follows:
Cannot synchronize with the corporate address list
This started after i moved from the LAN to the DMZ - we are needing to allow external communication to it, so i was forced to move it. any ideas on what might be blocking it? Upon logging in, it requires me to authenticate if my Outlook 2007 profile is set to connect with RPC/HTTP.
