Windows 2000 DNS server is misconfigured after upgrading from NT 4.0
My Windows 2000 DNS Server has a major problem (this was an upgrade from NT). Netlogon gives me a message that it "cannot register or deregister because there is no DNS server". Here's roughly what my DNS screen looks like:
-------------------------- ---------- ----
DNS
Computer-name
Cached Lookups
Forward Lookups
Reverse Lookups
-------------------------- ---------- ----
Here's what I see under cached lookups:
-------------------------- ---------- ---------
Cached Lookups
(.)
Net
.........other stuff
-------------------------- ---------- ---------
I have done an extensive amount of research and still don't know what the "Cached Lookups" domain is. Many articles I have read warn against the (.) root domain but they all say it would be under the "Forward lookup" zone, not under Cached Lookups. I don't get the option to delete "Cached Lookups". The server gives me the option to delete the "Net" folder but when I press delete it says: domain cannot be deleted - the zone doesnt exist.
I definitely feel I have to get rid of the "cached Lookups" folder to fix my problem, but I can't ( I have tried everything).
Here's my question:
My zone is Active Directory Integrated, what would happen if I deleted the "Computer Name" from DNS and started building the DNS over again? Will I get into real trouble with the Active Directory. I don't think it knows where the DNS is anyway. Or better yet, what if I removed DNS entirely and then added it back.
Or aternativelty is this something that "netdiag.exe /fix" would take care of?
Please do not point me to online documents - I have read all of them. And remember that I can't delete the (.) root folder. It doesnt let me (unless there is a tricky way to do it).

I follwed your directions and here's what I have
Make sure in the TCP/IP that the server is pointing to itself for DNS (once again assuming DNS is installed on this machine)
This is the case
Make sure "Append primary and connection specific DNS suffixes" are selected.
These radio buttons are selected
Check "Append parent suffixes of the primary DNS suffix"
This is the case
Check "Register this connection's addresses in DNS"
This is selected
Enter your AD DNS name in "DNS suffix for this connection"
The name was there
On the DNS server, make sure you have a zone that matches your AD DNS name. If not create it.
I did have a zone that matched the AD DNS name
I typed in the following command as you suggested:
c:\ipconfig /registerdns
I got a message: Registraion of resource records has started. Any error will be reported in the event viewer in 15 minutes. No error were reported
I ran the follwing command as well
c:\ipconfig /flushdns it did it's job
I stopped the DNS service and restarted it and then stopped and restarted Netlogon. Netlogon again gave me the follwoing message:
Dynamic registration and deregistration of one or more DNS records failed because no DNS servers are available.
Here's some extra info - (assume that my domain name is "mydomain", and computer name is "compname"):
Under my forward lookup zone:
Forward Lookup
SOA
NS compname.mydomain.
NS compname.mydomain.loc
A compname IP
I don't know why I have 2 NS records but I havent been able to delete one.
Also, I don't have any SRV records, which I think should be appearing automatically under the Forward Lookup - I am assuming that's what netlogon is trying to do and can't.
I think the machine, or the domain doesnt understand there is a DNS on the same machine. As a result I cannot add a new DC to this domain. When I try to do that I get a message saying "no domain found" or something like that. I can add workstations to this domain though without any problems.
I think I am hosed. What kind of troubles could I get into if I just delete the computer name from my DNS and start rebuilding it. Of course that's no guarantee that would work either. At the moment users can log into the machine and do their work and I don't want to jeopardize that.
I think I will add another 100 points for your trouble.

Well your setup looks good.
As far as deleting the Name server. Select the Name server, right click. Select properties, under the Name server tab, you should be able to remove the other entry.
It seems like the DCpromo didn't take (probably due to DNS). Look at the DCpromo.log file in c:\winnt\debug and look for errors.
Does NSlookup query the DNS? Make sure the server can atleast query itself.
Is the DNS server allowing Dynamic updates? This is needed for the records to be updated.
Is there a file in c:\winnt\system32\config called netlogon.dns This file will have the srv records in it.
What events are you getting in the Event logs?
If you are hosed, I wouldn't worry about deleting the zone. Recreate as a primary and try to have the DC recreate the records (Start Netlogon). I hosed my AD once and I entered in all the SRV records manually and AD came back.

Thanks for hanging in there. I should be able to take it from here.
Glad to help. I spent ALOT of time dealing with DNS issues when we setup AD. You don't learn unless you break something... and I learned alot.
(:
Good luck
(:
Good luck
I've broken AD many times and it usually always because of DNS. Removing the Computer name from DNS doesn't actually remove DNS, it just removes the ability to administer DNS on that computer. I wouldn't worry about the cached lookup zone, I have the structure you have and mine works fine.
What do you see under your forward lookup zone?
Anyhow, you should be able to remove DNS and reinstall. AD will be down, so I would do this after hours. I still wouldn't recommend it.
But first try this...
Make sure in the TCP/IP that the server is pointing to itself for DNS (once again assuming DNS is installed on this machine)
Make sure "Append primary and connection specific DNS suffixes" are selected.
Check "Append parent suffixes of the primary DNS suffix"
Check "Register this connection's addresses in DNS"
Enter your AD DNS name in "DNS suffix for this connection"
On the DNS server, make sure you have a zone that matches your AD DNS name. If not create it.
You may want to turn off Secure dynamic updates until DNS it working.
At a command prompt try:
c:\ipconfig /registerdns
This should register this server into DNS. I've had problems with not having the DHCP client enabled while using NIC Teaming.
c:\ipconfig /flushdns
This will flush the DNS cache. The server will look into cache before it query's DNS. This forces it to look at the DNS server.
If you are using NetBIOS, you might want to try:
c:\nbtstat -R
This is similar to /flushdns but for NetBIOS
c:\nslookup
This will allow you to query the DNS server to see if you can resolve things.
Also in the Windows 2000 support tools there a tool called Active Directory Replication monitor. This tool is good for checking replication problems.
What kind of events are you getting in the Directory Service, DNS, Replication event logs?
Let me know what happens
