 Outlook is requesting data from Domain Controller instead of Exchange server
Domain Controller, Exchange 2003, Global Catalog, Global Catalog on Windows Server 2003, Outlook, Subnetting, Windows Server 2003
Dear Experts, We are running a Domain Controller/Global Catalog on Windows Server 2003 (SP2) and Exchange Server 2003 (SP2) on a Windows Server 2003 (SP2). We have two subnets in our Network, 192.168.0.X and 192.168.6.x. When the users (all running Windows XP SP2) from the subnet 192.168.6.x tries to send mail from there Outlook clients (2003 or 2007) they see a RPC pop-up at the system tray, which indicate that Outlook is trying to retrieve data from the Global Catalog server instead of our Exchange server. And it stays there for about a minute and then only user would be able to send any mail. As far as I understood that the Outlook client is trying to look for GAL while sending sending mail to resolve the recipients name. But why is it taking too long to do that. Thanks, Nikesh

Answer Wiki:
Check your access lists between the two subnets. You need to add SMTP access to your exchange server for the 192.168.6.x subnet.

Hi Mshen,

Thanks for the response!
Access lists between the subnets are defined correctly and also 192.168.6.x subnet has SMTP access to the Exchange server
Do you know about any setting in the Global Catalog server which can cause this.

Thanks,
Nikesh

No issues concerning the Global Catalog that I know of. It seems more like an access issue. This
Link will give you a good list of ports you need to have open between exchange and outlook.

Test access by opening a few of the following ports:
IMAP 143
IMAPS 465,993,995
POP3 110
SMTP 25

The following UUIDs for Exchange work too:
