DNS on server forwards servername to outside IP.

Server: 2003 Server Standard
Clients: 8 XP machines.

lets just say my server name is "server-name"

When I ping server-name or servername from any client the ping comes back with:
Pinging server-name.domain [8.15.7.107]

I have no idea what is at 8.15.7.107.  My local range is 192.168.4.xxx

DNS is setup on the server.
It looks to itself for DNS info.
1 forwarder is setup. The router (it gets DNS info from ISP)
 - I've tried using the ISPs DNS directly.

If I sit at the server and ping server-name my server responds.  I only have this problem from the workstations.

There is nothing in the hosts file.

I have one brand new computer as well.

Also, in my Forward lookup zones I have under _msdcs.mydomain.local then domains, then 5dcb8089....  what is this?  Can I delete it?

Do an ipconfig /all on a client and see where the clients are getting their dns info from?

from the server.

DNS and WINS.

Is your domain an internal domain or are you using an externally named domain inside the company? i.e are you using domain.local or domain.com

and when you ping the server from the server does it come back with the fqdn or a netbios name?

from the server I get a response from my server IP.  server-name.mydomain.local

from a workstation I get the wrong IP and server-name.mydomain  but no .local

I've been chasing this problem down in the DNS.  Could this be a WINS issue? Do I need WINS at all?

Can you run ipconfig /flushdns on a client and re ping if still the wrong IP
Then goto cmd from the workstation and run nslookup, it 'should' look directly to the server for it's lookup (double check that).
type set q=a
then type the servername and see what it comes back as.

when I flush DNS I get the same problem.

nslookup looks to the server for advice.

when I lookup server-name I get 8.15.7.107, 63.251.179, 65.200.200.47

I have no idea what those IPs are.

the 65.200.200.47 is a
MCI Communications Services, Inc. d/b/a Verizon Business UUNET65
the 63. address is in valid missing an octet

63.251.179.17

Oh Boy.  I looked up those IPs.  They are Rogers (my ISP).  When I have a failed DNS lookup it gets redirected there.

Ok, so I am getting a failed lookup from my workstations.  Why do you think that is?

Can I stop this lookup?

check your forwarders on the server and see where they are pointed

And you are sure that what they point to are DNS servers?

yes.

I just changed them to OpenDNS servers at:
208.67.222.222
208.67.220.220

Now when I ping my server 208.69.36.132 tries to answer the call but times out.

If I ping the word "wingbat", the same IP comes up.  Says wingbat.mydomain

NSLOOKUP:
if I lookup server-name, I get:

Server: server-name.mydomain.local
Address: 192.168.4.200 (this is correct)

Non-authoritative answer:
Name: server-name.mydomain
Address: 208.69.36.132

Huh...

I've removed WINS as a role, then removed and reinstalled DNS.

Currently I have no DNS and no WINS.

I can ping server-name.

Can't browse the network but I can ping the server.

and to continue rambling

I've now reconfigured DNS and WINS.

ping and nslookup are both good.

I can navigate to \\server-name\ with explorer

I can't browse mydomain in network hood.  

I have no forwarders setup in my DNS.  I guess it is using root hints.

Browsing error:

mydomain is not accessible.  You might not have permission to use this network resource.  Contact the Administrator of this server to find out if you have access permissions.

The network path was not found.

Well if you can ping the server thats a good thing.

For network browsing.
Go to this from the name server
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Browser\Parameters
Verify ISDOMAINMASTER is TRUE
MainainServerList is Yes

Restart browser service on the name server and it should force an election. Then wait...Shouldn't take more than about 15 mins but you should be able to browse from the name server after that. Then try from a workstation.

Strange..Browser service doesn't rely on wins so it shouldn't have an impact on it.
In the support tools there is an app called browstat, run that(from the server) and it should tell you whats going wrong. Also look for browser announcements in the event log to make sure there isn't another server/workstation that thinks it should be the master.

The whole server started acting up.  It locked, other applications hung etc.. It was old.  I put in a new one.
