Sbs 2016 dhcp not updating dns

Rated 3.93/5 based on 937 customer reviews

Is this just a "bug" in SBS 2008 in that it will only DNS register Windows-only DHCP clients?If so, I guess I'll live with the DHCP reservation solution.

Please see this: and this: Sorry for the delay - this question fell off my radar.

Technet says something about setting option 81 but I don't even have an option 81. I assume this is set, but on the client network adapter under your ipv4 or 6 properties and then advanced, under the dns tab you have the option "Register this connections address in DNS" checked correct? We are experiencing the same thing in our environment. It seems to occur once every couple of days and only on our 2012 R2 DC not on the other 2003 DCs in the forest.

On the server that has a 'missing' DNS record - if I do ipconfig /registerdns - then it is put back in. Obviously that only band-aids that one server and doesn't fix the root problem.

This one does *not* have the hostname set, but appears to work propertly anyway.
