hi,

users cannot join the domain due to dns issues.....the server is missing
records such as _msdcs and getting eventID error 5781 on a win2k dc
how I populate DNS with all the required srv and _msdcs records since
all there is now is one A record for the server

when You are saying server is missing entries in _msdcs zone You are
talking about DC as a server?
To register this records for DC just ensure thath DC in the TCP\IP
settings is pointing to good DNS server and restart netlogon service

If this DC is pointing to itself, ensure that the DNS zone is configured to
accept dynamic updates and ensure that the DHCP client service is running
and set to automatic (even though your DC isn't a DHCP client).

Then delete the _msdcs domain and restart netlogon.

Or you can run netdiag /fix

I created a new forward zone called " _msdcs.domainname " and cycled the
netlogon service which resolved the issue and populated all missing entries

If this DC is pointing to itself, ensure that the DNS zone is configured
to
accept dynamic updates and ensure that the DHCP client service is running
and set to automatic (even though your DC isn't a DHCP client).

Then delete the _msdcs domain and restart netlogon.

Great news!!!

Did you create any of the sub-domains yourself? If so, this is not
recommended. However, if you did restart netlogon all should be well. In
the future restarting netlogon will suffice; if you create the A records
yourself, you may accidently add invalid entries, which could cause
problems. In future, let the DHCP service worry about it...

restarting netlogon hadn't fixed the issue...I didnt add any entries just a
forward zone called _msdcs.domainname...then restarted netlogon

If restarting netlogon didn't fix this, then you need to check that the DHCP
client service is running and is set to automatically start. If it is,
restarting is all you need to do. It can take a couple of minutes to take
effect.

netdiag /fix will also do this, but netlogon should. As it checks/ does
this every twelve hours.

Delete the _msdcs domain and restart netlogn. Go make a coffee and see what
happens. If it's not re-registering then we need to address this...
