Outlook crashing at one site since DC swap

[sidewinder]

We have 3 sites, one main site with the Exchange (2010) server, and 2 others on the same domain but connect to Exchange across a leased line. Each site is on a different subnet.

 

At one of the 2 remote sites over summer I replaced the DC/DNS/DHCP server. Since then, Outlook 2010 works, but crashes with alarming regularity. The error logged is:

 

Source:        Application Hang
Date:          16/08/2013 14:22:16
Event ID:      1002
Task Category: (101)
Level:         Error
Keywords:      Classic
The program OUTLOOK.EXE version 14.0.6117.5001 stopped interacting with Windows and was closed. To see if more information about the problem is available, check the problem history in the Action Center control panel.

 

Now the main site is absolutely fine and the other remote site is too. And it is occurring on all machines at this one site. So it has to be related to changing the DC. The server has a different name and IP address but DNS is all setup correctly, DHCP is handing out addresses with the right DNS details, everything else works fine.

 

It's probably something really obvious network related that I have missed but I can't figure out what at the minute. Any ideas? The IP range hasn't changed and the Exchange server hasn't changed

Still an issue?

Well creating a new Outlook profile on the offending machines seems to sort it. But I would like to know what caused it!
