Why Outlook 2003 is unable to connect to Exchange 2003?
Posted on 2011-10-13
Origin: single network single domain (Windows 2003):
default gateway: 10.0.1.1
svr-exch: 10.0.1.13; dns = 10.0.1.11/12
workstations use dhcp.
all servers and workstations are in the same network.
No issues noticed.
segment workstations from servers as follow:
servers stay the same
workstations are put in 10.0.2.0/24 network
use dhcp to dispatch ip (10.0.2.x) and dns (10.0.1.11/12);
workstations are able to ping servers by ip and host name;
There are no dc in 10.0.2.x network.
Issues noticed so far (6 days since change):
A few users are not able to open Outlook properly. When setting up the user's Outlook profile again, Outlook says 'The name could not be matched to a ame in the address list'. When trying to set up another user, Outlook is unable to resolve the mailbox even though the mailbox is there.
Q#1. Is the above issue related to the above network change? If yes, what's the ultimate cause?
Q#2. Any potential issues if there is no domain controller in the new user segment? for example, will computer accounts become out of synch with AD?
Q#3. If there must be a domain controller in the new user segment, is it easy to modify svr-dc-dns2 and put it in the new 10.0.2.x network?
Q#4. Will more uses run into Outlook issues?
