DNS Setting Issue

[PreviousPoster]

As part of our default Domain Policy, which is enforced, I have a setting under
Computer Confi >> Admin Templates >> Network/DNS Client
We have
-DNS Servers Enabled, with two IP's, space delimited as it calls for
-Dynamic Update enabled
-Primary DNS Suffix enabled

However, some of our PC's, which are part of the domain, are not getting this particular part of this policy, while the rest of the policy's options work fine.

Single Domain. 2 DC's running W2k3 R2. Workstations are all XP.

Anyone have any ideas where I could start with this one?

Why are you using Group Policy to do this when DHCP is far more efficient and meant to handle this task?
