I received an email from our T1 provider telling me that they were
discontinuing services on some of their DNS servers. We were given a
list of their new local DNS servers.

Our T1 comes in via their Netopia router. Then it travels to our
router. We run DHCP and DNS off of a Windows server.

When I changed the DNS settings on our router I can no longer ping. It
just times out. Everything else seems to work fine, though. When I
change back to the old DNS servers (which weren't even the ones they
mentioned) I can ping again.

Any ideas?

Hi there !
How the nslookup works after that change ? Also did u try flush dns ?

I tried everything! I finally called the T1 provider, and asked them
what DNS servers I should have in there. They gave me the correct
information, and everything is normal now.
