We have a single forest/single domain and are in the process of decommisioning a 2003 domain controller that both the Exchange 2003 Enterprise and Domain Recipient Update Services are pointing to.  We would like to repoint the Recipient Update Services to a 2008 R2 domain controller.  Is there anything to keep an eye out for or any gotchas when performing this change?  Thanks.

Just browse and change it to new DC. Make sure DC is up and running when you are doing this change. Rest is simple.

Make sure you have a good backup before doing this. There are no gotchas but you have to be very careful because you have to do this using ADSi Edit: http://social.technet.microsoft.com/Forums/en-US/exchangesvradminlegacy/thread/23782bd7-9a92-452b-b327-41809bbc4dbf

clonyxlro: It can be done via ESM itself. I don't think ADSIEdit is required here.

The DC RUS is currently pointing to and the DC it will be changed to are both up and running.

I second Amit to simply change the DC for RUS from the ESM and not get into ADSIEDIT until its no otherway

Hopw you have moved the FSMO roles and ensured that your exchange can work with Windows 2008 server ??
Did you check event 2080 on the Exchange Box and also it appears in the DSAccess tab

Good Call Rancy regarding FSMO. Also make sure 2008 DC is also a GC.
We haven't moved the FSMO roles yet but are planning to before decommisioning the DC.  FSMOs are not relevant for changing the DC the RUS's are pointing to, right?  All the DCs in the forest are GCs.

Yes that is correct, FSMO roles has no relation with RU's.

Yes FSMO roles dont have a call with RUS but just ensuring we try to cover the point and as said if RUS is repointed and all is working i guess the Post can be resolved and if you have other doubts you can call another post :)
