Re: XP clients not updating DNS via DHCP

Kevin,
It was a DC with DNS, when I demoted it to a member server, I stopped
the
DNS server service and changed DNS server settings on all my dhcp
servers to only point to the one dns server I have left running which
is (MS-SVR - a win2k (dc) it is ad integrated).

This was one of the scenarios I gave.

I hope this helps.
I noticed something interesting. I setup a pc on the same subnet with
the DNS server. I get an ip address with all the right settings. when
I do a nslookup -da ipaddress of pc, I got a list of three reverse
entries, only one of which was the correct pc name. if I do a
nslookup -da pcname of pc, I get an IP address of some other pc. I
guess I am really confused as to how removing one dns server (I had
two, now have 1) would make it so my dhcp servers stop updating dns
correctly.

Really beginning to worry, (should I panic yet?)
Robert

When DHCP runs on a Win2k DC, it uses the DC's permissions to update DNS,
which is why you shouldn't run DHCP on a Win2k DC.
When you demoted to a member, it no longer had permission to update DNS, you
would have to add DHCP servers on Member server to the DnsUpdateProxy group.
But, I still wouldn't recommend that. Win2k3 DHCP will work much better as a
DHCP server.
