Netlogon event 5781 - SBS 2008 _msdcs zone
Posted on 2011-03-12
I'm currently troubleshooting a SBS 2008 box we have recently been asked to take a look at - there are a host of issues, and I'm tackling them one by one.
I can see that there are periodic NETLOGON event 5781 which state that dynamic registration or deletion of DNS records fail associated with DNS domain 'myserver.local'

Doing initial required tests
Testing server: Default-First-Site-Name\SERVER01
Starting test: Connectivity
not be resolved to an IP address. Check the DNS server, DHCP, server
......................... SERVER01 failed test Connectivity
In my DNS manager I have the following forward lookup zones;
Underneath the first lookup zone, is the following;
However, comparing this with another sbs 2008 box, I can see that the forward lookup zones are as follows;
So I'm thinking I need to delete the delegated _msdcs entry and create a new zone labelled _msdcs.mydomain.local.
I'm seeking guidance, that this is the correct approach to take, and preferably some further advice as how to go about doing this.
