I have been analyzing a problem and I wanted another opinion.
VLAN A - group policy replication works fine. There are no ACLs between here and the server.
VLAN B - group policy replication does not work. There are ACLs between here and the server.
I have analyzed the syslog messages for a computer in VLAN A and VLAN B. There are no denies in any of the syslog messages. The only thing I can find which is "odd" is a TCP RESET-O setting for the /88 (Kerberos) quite often with the traffic in both VLANS. There is NATing going on in the environment. I wanted to find out if any of you have run across this issue and had any advice. If there was deny traffic, it would be an open and shut case. There isn't so it seems that something is related to network side of things, but I'm not seeing immediate issues. Thanks for your suggestions.
TCP Reset-O means that the computer sent a query to a server in specific protocol and that server was not listening for this protocol, port 88 is the standard port that is being used by kereberos.
