Second DNS server showing up with DHCP

[xevious2k]

Greetings All,

I have a small problem and am a little lost. We have 4 W2K servers 2 file servers, 1 mail and a VPN server. One of the file servers is the big kahuna of the group and takes care of DNS and DHCP. My DHCP scope is setup to have only 1 DNS server, (200.200.200.6), but when the clients get their DHCP config, our ISP DNS server is listed in addition to the one above and I can't find out where it's coming from. The DNS server is setup with forwarders to the ISP's DNS servers. Here is what the ipconfig shows...

H:\>ipconfig /all

Can anyone tell me where the DHCP client is getting the 205.247.216.2 address from so I can get rid of it?

Thanks,

Is the ISP DNS server listed in your DHCP scope options? If it is, then clients will have this when they obtain an IP address. The ISP DNS server should only be listed under the Forwarders tab and not in the scope options.

Only 1 server is listed in the DHCP scope, (200.200.200.6)

sorry, it did say in your first post that you had only one DNS server in your scope. i blasted through it and did not catch that, sorry. that is rather odd, i have not heard of this happening before. i can't think of anything else off hand that would/could be causing this. i tried doing a google search and nothing is comin up with regards to this. i'll see what else i can turn up and if you resolve it in the meantime please post back here as i am sure this will happen to someone else.
