Re: DHCP assinged DNS servers don't work

Hello,

I've posted this issue in other newsgroups with little success. Hopefully
someone here can help me.

I have 75 WinXP machines on a Win2K3 domain using DHCP for address
assignment. I have found that for some machines, using the DHCP-provided DNS
servers fails to resolve all internal host names. If I use DHCP for the IP
address only and manually add the DNS servers, name resolution works every
time.

In more detail, if I use DHCP to assign the name servers, the ping command
will fail on certain internal hosts. However, nslookup works every time. If
I manually assign the name servers (using the same addresses provided by
DHCP) ping works and so does nslookup.

Any thoughts or ideas are greatly appreciated. This problem is preventing
me from taking a new system live because a number of machines can't resolve
the name.

I have seen a similar behaviour only with the Windows Live One Care Firewall on my laptop. That blocked DHCP and DNS traffic by default.
What is the output of ipconfig /all on the affected clients?
Are the client PCs "multihomed" (multiple network interfaces)?
Best greetings from Germany
