Windows 2008 DC's still trying to communicate with decomissioned DC's
Hi there. I have 2 fairly new Windows 2008 DC's in a single domain. I went through the process of decommissioning 2 old Win2k DC's using dcpromo. everything seemed to go smoothly.
For some reason i can still see entries in the logs of the Windows 2008 DC's referencing the old DC's.
I am seeing Event ID 1925 where the new DC's are still trying to replicate with the old DC's.
also Event 1864 saying that it has not received replication information in quite some time from 2 Directory servers.
At this time, I am not having any issues, but I wonder what steps i missed to cause these errors and if this will cause problems in the future.
thanks!

If you delete the DCs in the Domain Controller OU, metadata will be cleaned automatically. This is new to Windows 2008 and Windows 2008 R2.
you can use the article below to cleanup metadata:

Thanks for the input everyone!
I did find and remove some traces of the old DC's in DNS and It looks like I do need to remove them from Sites and Services.
When removing the old DC's from Sites and Services, I get a message that "the object contains other objects. are you sure you want to delete all objects it contains?"
The only things I see associated with the old DC objects are connections to other DC's under NTDS Settings.
Is it safe to just delete the Server objects for the old DC's or should I remove the connections first?
thanks again!

Ok. So I could not delete the objects as they were. I had to delete the connections, then delete the NTDS settings for each of the old DC objects, and then I was able to delete the Server objects.
I think I'm all set. I will monitor the logs just to be sure.
Thank you all for your help!
