Server 2016 r2 dns not updating - error crashed while validating asset
The following list illustrates a typical example of how a private DNS update leaks out to the global Internet. The DHCP client first sends a query to its local domain name server (LDNS) and asks for the authoritative server for the zone of its domain name (step 3).Once the DHCP client receives a response (step 4), it sends the update to the indicated server (step 5).
If you're waiting on DNS scavenging, there's no fast way to do it.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. I guess that the forward lookup records are created by the host, but the reverse records are created by the 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.The reverse lookup zone exists, and I can add entries to it manually, but it doesn't automatically populate.
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?
``So what if my host leaks a few packets to the global Internet? '' The reason is that inconsistent configuration between your home hosts and your local DNS servers can, and often does, cause leakage of DNS updates for private IP addresses to the global Internet.
This leakage causes the following problems: Unfortunately, most users have no knowledge of their own misbehaving hosts broadcasting private information to the world.
This article covers the default security settings for DNS zones: the settings are jacked up (or even if they are fine), you might try just blowing away the reverse zone and recreating it since you basically have a non-functioning reverse zone as it is...
Try running an "ipconfig /registerdns" on one of the clients and see if it adds a record to the reverse zone.
Changing the timeouts is only going to help clients the next time they check in, which is usually after half the existing lease time, or sometimes during boot.
