After upgrading to windows 2008 R2 domain, our exchnage 2003 server still look for old GC server which was a old DC also, and gives error in application event log as Event 8260. We do have both our new windows 2008 DCs are mrked to be as GC but exchange still look for old. Is there any chnages need to be perform at exchnage level while upgrading of domain or after then?

In Exchange System Manager, expand Servers, right-click your Exchange server and then click Properties.

Click the Directory Access tab.

In Show, select Global Catalog Servers.

Check the Automatically discover servers check box

Yes the NIC has new DNS addresses.
Automatically Discover Servers check box is checked and I can see both the new DC and GC are in the list there. There is no entry of old DC/GC.
Still I get following errros in application event logs,
