I renamed a Windows Server 2012 R2 Standard computer from NAME1 to NAME2 using netdom, and then I rebooted the computer:
netdom renamecomputer NAME1 /NewName:NAME2
In DNS, I had an A record for NAME1. To support the rename operation, I reconfigured DNS as follows:
- create A record for NAME2
- delete A record for NAME1
- create CNAME for NAME1 pointing to NAME2
Now when I try and RDP to NAME1 from a Windows 8 Enterprise x64 computer, I get the following error dialog from Remote Desktop Connection:
An authentication error has occurred. The specified target is unknown or unreachable Remote computer: NAME1
When I RDP to NAME2, it connects with no problems.
I thought the CNAME might be to blame so I decided to test things with a different computer, TEST1. I created a CNAME for TEST2 pointing to TEST1, then tried RDP to the TEST1 CNAME, which worked. TEST1 has the same OS version as NAME1.
So I think the netdom renamecomputer operation broke things, not the CNAME.
How can I make it so that I can RDP to NAME1 again?

Maybe not the error, but check if LANMAN is configured to use the alternative's name.
Value name: DisableStrictNameChecking = 1 (DWORD - DECIMAL)
nb. The strictnamechecking value is there to refuse a access to it by a different netbios's name.
