DNS Suffix Search List and Netbios Name - Where did they get configured?

On our workstations, we have three DNS Suffix Search List entries when you do an IPCONFIG /ALL.  The systems are not DHCP enabled, that have static IPs.  Yet, there are no suffixes entered for the properties of the TCP/IP settings for the network connection.  Nothing found in the registry either... So, where are these machines getting these suffixes from?

Also, we have a DC that when you do an nslookup by IP, it returns the wrong name.  It doesn't match it's host name.  We don't have reverse-lookup zones setup yet, but I presume this is a netbios name that was originally configured for the machine before it was dcpromo'd as a DC.  How do we change it's netbios name... Again I could not find it in the registry of computer name settings.

I looked at all the group policies, and I could not find anything there.  I even ran the rsop wizard... nothing.

I tried the debug command... New-dc-5 is not the hostname of the dc.  So I don't get where it gets that from?

Server:  new-dc-5.lan.com
Address:  192.168.224.10

Got answer:
    HEADER:
        opcode = QUERY, id = 2, rcode = NOERROR
        header flags:  response, want recursion, recursion avail.
        questions = 1,  answers = 1,  authority records = 0,  additional = 0

    QUESTIONS:
        10.224.168.192.in-addr.arpa, type = PTR, class = IN
    ANSWERS:
    ->  10.224.168.192.in-addr.arpa
        name = new-dc-5.lan.com
        ttl = 10258 (2 hours 50 mins 58 secs)

Have you checked under the TCP/IP->Advanced->DNS tab to see if they are listed there ?

Yes, I have checked in the advanced section and they are not there... That's what's puzzling...

FYI... The part about the netbios names, is no longer an issue
