RDP login issue on Server 2008 R2

[subitt32]

Dear All,

I am having problem with my domain controller. I have one domain controller server 2008 R2 named previously dc.ABC.com

I have changed the domain name to dc.XYZ.com with NETDOM command and followed the document which is available on many websites.

Now on end user side, I have no problem but on the domain itself, I am able to login through RDC with new domain name like, XYZ\administrator, which is absolutely fine but I am still able to login with my old domain name like ABC\administrator with the same password. There are no traces of any kind in DNS regarding old domain name e.g.: ABC.com after migration.

Any help would be highly appreciated.

TIA
