Windows clients not updating dns
The TCP/IP Settings window calls this the Primary Suffix.If a query using the primary suffix fails, and the Append Parent Suffixes option is checked, the resolver strips the leftmost element from the primary suffix and tries again. The TCP/IP settings for each network interface can have a unique DNS suffix, populated either statically or with DHCP.The servers use static mappings to the same external DNS servers.During the PDC upgrade, you install DNS because DCPromo tells you to.Worse still, the internal server must reach through the firewall and connect to a variety of DNS servers, some of which could have traps that play malicious games with DNS requests.
The member computers don’t know that the domain has been upgraded to AD unless they just happen to authenticate at the PDC. Users treat additional keystrokes as if they were penalties visited upon them by uncaring IT bureaucrats. The resolver obtains this DNS suffix from one of several places.Don’t forget to include the FQDN of the local domain as the first option on the list.Ordinarily, when a client confronts its DNS server with a request for a resource record in an outside domain, the DNS server searches for a name server in the target domain and submits the query to that server.This standard query resolution has a couple of problems.First, the internal server can get so preoccupied chasing down recursive queries for public hosts that it runs out of resources to handle queries for its own zones.
