I have a strange issue. Out of no where one of my machines stopped receiving the computer policy. This system is a sysprepped clone. All other PC's in the OU are receiving GPO's as they should. Otherwise they are identical in configuration. This one was working fine up until a few days ago. Zero changes have been made to machines in almost two months. So to resolve this, I ran RSoP on the machine and it in fact shows a red x for computer GPO's. I removed it from the domain then deleted it from it's OU. I then renamed it and joined it back to the domain and placed it back in the OU and rebooted several times. It still does not receiving computer GPO's, but it does receive User based GPO's just fine. I checked event viewer and it gives a Group Policy error saying the name can not be resolved to our DNS server. All other PC's in the OU are receiving the GPO's. I don't think this is a configuration issue since it worked up until a day or two ago. On the DNS server I checked the AD integrated zone and I see the Host A record for the computer name and it's IP. It's identical to all of the other records. I have DNS scavenging enabled. What else should I try? For a side question, I notice that when I ping host names from the server, I get no response from any workstation. When I ping IP's I do though. How can AD even be functioning if the server cannot see the PC's based on host name?
