My organization is having an issue with GPO application which is possibly caused by DNS. Most Directory activity seems to be working fine but group policy is failing to apply on some machines and I have also seen a few other oddities (ADFS 2.0 webpage is not accessible.) The issue was first noticed on our Terminal Servers when ever a policy refresh was attempted. I have run DCDiag on each machine and repadmin /showrepl and have found no problems. All SRV records are in place. Below is an example of one of the events recorded on a Terminal Server:
<ProviderName="Microsoft-Windows-GroupPolicy" Guid="{AEA1B4FA-97D1-45F2-A64C-4D69FFFD92C9}" />

Any ideas as to why this can occur and why only on certain computers?
