Windows 7 DNS Group Policy not applying

active-directorygroup-policywindows

I've created a group policy in my GPO editor, under default domain policy -> Computer Configuration -> ADministrative Templates -> Network -> DNS Client -> DNS Servers, and put in my couple of DNS servers. I forced the update on my client with gpupdate /force, and then checked my results with gpresult /z >c:\outfile.txt. There, I see my configuration:

        GPO: Default Domain Policy
            KeyName:     Software\Policies\Microsoft\Windows NT\DNSClient\NameServer
            Value:       49, 0, 48, 0, 46, 0, 50, 0, 51, 0, 52, 0, 46, 0, 50, 0, 48, 0, 49, 0, 46, 0, 49, 0, 48, 0, 32, 0, 49, 0, 48, 0, 46, 0, 50, 0, 51, 0, 51, 0, 46, 0, 56, 0, 54, 0, 46, 0, 49, 0, 49, 0, 0, 0

…I have looked at the value and it appears correct, looking up the decimal values in an ASCII table.

The problem is, the workstation does not seem to obey the group policy. I can do into the network card configuration and muck with the DNS, set it to whatever server I want, break it how I like.

I also set the DNS Suffix Search List and that looks correct, AND it's greyed out and I can't edit it.

How come my DNS server settings aren't sticking? …If they were, I wouldn't be able to break my DNS but I can by hardcoding an incorrect IP address.

I have a Windows 7 workstation and a Windows Server 2003 Domain Controller (obsolete I know, but anyway the gpresult output looks fine to me).

That GPO setting is supported only for Windows XP Professional clients.

As an aside, why are you setting the DNS servers with Group Policy rather than assigning them via DHCP?
