For those who are willing to add it directly to the registry, save the following content in a *.reg file:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINESOFTWAREPoliciesMicrosoftWindowsCredentialsDelegation]
“AllowDefCredentialsWhenNTLMOnly”=dword:00000001
“ConcatenateDefaults_AllowDefNTLMOnly”=dword:00000001

I got it by doing it manually and then searching the registry for TERMSRV.
