Windows dhcp not updating dns sochi dating

We have multiple hosts as of late that sucessfully pull a DHCP address and are domain machines that there is no A record being created for the host.

I can do a reverse lookup on the IP and that works but not name to IP.

If you are working with, well almost anything network intensive these days, like Antivirus or management tools, your Reverse DNS (r DNS) lookups need to be in good shape.

If you find that you can not resolve IP’s back to a name on your network check your DNS REVERSE LOOKUP ZONE.

Clients with dynamically-set network connections (DHCP clients) will communicate with both the authoritative DNS server and the DHCP server for updating A and PTR records.

The DHCP client will communicate with the authoritative DNS server directly for updating its A record, but the DHCP server updates the DNS server with the client’s PTR record In some cases, a DHCP server may update a client's A record on its behalf, even if the client did not specifically request this.

From there, the client continues communicating with the primary DNS server that accepted the A record update.

Please see For a static client, the client will communicate directly with the authoritative DNS server to update its PTR record.

It is an issue on Server 2000, 2003, 2008, 2008R2, Server 2012, Server 2012 R2 and will likely be an issue in the newer builds.

Any suggestions would be greatly appreciated, Thanks.

If you check your servers event viewer you will see EVENT ID 1056: The DHCP service has detected that it is running on a DC and has no credentials configured for use with Dynamic DNS registrations initiated by the DHCP service. Credentials for Dynamic DNS registrations may be configured using the command line “netsh dhcp server set dnscredentials” or via the DHCP Administrative tool.
