Windows 2008 R2 domain controller

Two Win2K8R2 DC’s with temp names were added (migration) to W2K3 network w/2 existing DC’s, tested and checked according MS recommendations.
During renaming something went wrong with one of the DC’s:
1.      The DC exists in ADUC / Domain Controllers with the new name.
2.      In AD Sites and Services the temp name still appears, replication to the second Win2K8R2 DC fails with error msg: “The RPC server unavailable. This condition may be caused by DNS lookup problem”.

Please help resolve the problem keeping in mind that most of MS hints were unsuccessfully tried.
Are the two new DC’s all the same?
Thank you.

Was everything working fine before the rename?   What MS hints did you try?  Did you see this article about RPC errors

You were renaming the DCs? To the old DCs name?

Run dcdiag post results.

If both W2k8R2 DC's identical, maybe the easy way just to rebuild the "fallen" one? (the old W2k3 DC's are not demoted and online)

The 2003 DCs are NOT demoted? Did you rename those DCs to something else?

Run ipconfig /flushdns, ipconfig /registerdns, and dcdiag /fix

Restart netlogon service

If this doesn't change anything then a demote of the new server would be quick and easy.

Yes, the 2003 DC's were renamed to "nameold".
Already ran ipconfig /flushdns - didn't make changes.
Will follow your recommendations.

Thanks.

Yeah demote it and run metadata cleanup to remove bad objects

Most likely will need to do a dcpromo /forceremoval

Yeah I don't think the GUI works unless you are running Windows 2008 Server domain level
