Symptoms

You try to join a Windows Server 2008 R2 or a Windows 7 machine to an Active Directory domain using Computer Name/Domain Changes under System Properties.
The destination domain has either Windows 2000, Windows Server 2003, or Windows Server 2008 domain controllers and may have Windows NT 4.0 domain controllers present.When trying to join the Windows Server 2008 R2 machine to the domain by specifying the fully qualified domain name (FQDN) in the domain join UI, the operation fails and you receive the error:

An Active Directory Domain Controller (AD DC) for the domain <target DNS domain name> couldn't be contacted
Ensure that the domain name is typed correctly

In the %windir%debugNetsetup.log on the client you see the following sequence:

When trying to join the Windows Server 2008 R2 computer to the domain by specifying the NetBIOS name in the domain join UI, you receive a different error:

Domain joins by Windows Server 2003 computers to the same target domain succeed by specifying the NetBIOS domain name in the domain join UI. Domain joins using the FQDN also fail.
You can also successfully join the same Windows Server 2008 R2 machine to a different Active Directory domain in the same forest specifying the FQDN domain name.

Cause

The errors occur if NT4Emulator is set to 0x1 in the following registry subkey of the helper domain controller used to join the target domain:
HKEY_LOCAL_MACHINESystemCurrentControlSetServicesNetlogonParameters
Value Name: NT4Emulator
Value Type: REG_DWORD
Value Data: 1

Resolution

To resolve this issue either delete the NT4Emulator registry value on the Active Directory domain controllers in the destination domain if Windows NT 4.0 domain controllers are no longer present or can be retired. Otherwise, set the following registry value on the Windows 7 or Windows Server 2008 R2 client before attempting to join the domain:
