Windows dhcp not updating dns records
The DHCP server in this case is NOT a windows server. The only thing I had to do after this was, flush the dns entries on the clients with: ipconfig /flushdns After this they have poped up in my reverse lookup zone. The fix of adding the DHCP server to DNSupdateproxy group solved my issues.
Dynamic updates are enabled for both the forward and reverse zones. This could be due to a couple of different things: 1) Are your clients obtaining IPs via a Windows DHCP Server?If they are in the forward zone but not the reverse, then something else is going on...3) If the issue is that your reverse zones are mismatched between domain controllers (meaning a host was able to register with one of the DCs, but the registration did not get replicated to the others) it could mean the zones themselves aren't replicating between domain controllers.If so, your DHCP server may not be configured to auto-register their IP with the DNS server.To check, right-click your DHCP scope and go to properties.
On the DNS tab enable DNS dynamic updates and set to "Always dynamically update..." Also enable Dynamic Update for clients that do not request updates.
