old DNS address hanging around

I've rebuit my network and am having a strange problem. Although DHCP
works fine on the clients and all the new data is being read, a few
utilities still see a very old DNS server address as the primary DNS
server. Things like winipcfg shows the old DNS server, for example,
even though the command-line ipconfig utility shows the current one.
The WildPacket inet utilities see the old one too. This is very
annoying since I have to manually change the address whenever I use
one of these tools.

I looked for the old address in the registry and it ain't there.
Anybody got any ideas where to look? Is it encoded into some other
form?

Thanks for any help.
 
Must be configured IN THE tools.

Changing the DNS addresses on a machine is effective
for all programs that don't save their own settings.

As long as IPConfig shows the right address you have
it correct. (I would never have expected WinIpCfg to
show an "old one" -- at least not the one from Microsoft.)

Since WinIPCfg doesn't come with Win2000+, my guess
is that you have a 3rd party version?

It's not; they use the system settings but can't find it.

It's part of the reskit.
 
Output "Ipconfig /all" to a text file and post the
names of the desired and undesirable servers with
that text file appended.

first, ipconfig shows the correct server:

Z:\>ipconfig /all

but wntipcfg.exe (the winipcfg util from the reskit) and iptools still
shows the old primary DNS server address:

I can't find any reference to this address in the registry, so if it's
in there it is encoded or something.
