The clients are not getting a software update from a GPO because they aren’t getting the server’s records from DNS. Authentication IS occurring as normal via Kerberos (which requires DNS), and network shares are accessible. If ping the FQDN of the DC from the client immediately after logon it resolves, after flushing the dns cache on the client it no longer resolves the FQDN. Ping to the server’s IP gets a response. After an undetermined time period the client will resolve the FQDN even after flushing the cache. I rebooted the server to no effect. My XP workstation eventually installed from the GPO although it is the only one so far. What is going on!!! The SOA NS and glue records of the DC look OK in the DNS server console.
