no _udp SRV in DNS

[Ryan Birkenholz]

I am having problems with my active directory (Win2k server) and everything
is pointing to the DNS. I have a server acting as a DC and running DHCP and
DNS. Someone told me that under the forward lookup zone I should have
certain folders listed one of them being _udp. I have several folders
(_tcp, _mscsd, _sites) but no _udp. Is this a problem and how might I
resolve it. I have recreated the zone a couple of times with no luck.
Other problems I am having that might be related are that I cannot ping my
default gateway to the internet although the internet works fine. I also
cannot ping this server, which has a public IP from any remote network.

My main problem I am trying to fix is that when I try to start up AD, it
says that no authority could be contacted. I have a feeling if I fix this
other stuff then my AD will work again. I also understand that the DNS
forward zone must be identical to the AD domain name. Where can I find out
on the server what the AD domain was named? I am almost positive I have
them set the same, but I didn't knwo where to check to see what the AD
domain name was.

Thanks!

I would try a couple of things:

Try installing the Support Tools from the Service Pack CD or from the MS Web
Site and run netdiag /fix from a command prompt. This could resolve the
issue.

Another way is to run the following from the command prompt:

net stop netlogon
ipconfig /flushdns
ipconfig /registerdns
net start netlogon

I have tried all of these commands as per a tech guide on microsoft.com and
none of it seemed to help. I still don't have the _udp folder in my forward
lookup zone.. Correction on my first message though...I can ping my gateway
from the server. I cannot, however, ping this server's public IP from a
remote network.

Ryan,

My post to you has not shown up in my newsgroup reader in the microsoft
Active Directory for WIN2000 news group....so, I can not check what I
wrote.....

I think that I might told you that the location of both netlogon.dns and
netlogon.dnb is c:\winnt\config. That would be one directory short of
correct! ;-)

The correct location would be c:\winnt\system32\config. Naturally, I am
assuming the default installation.

Sorry for *almost* correct information the first time around.......
