Re: clients using DHCP cannot resolve names after a while

absolutely, they are our AD DNS servers. I need to clarify something, I
forgot to mention that we can resolve anything that is either in the cache or
on the AD network, but when this happens it's another domain that we can't
resolve names to. It's weird because when the issue arises we can get a
response from whatever is in the DNS server cache but it won't forward to the
the other domains DNS server unless the nic's are configured statically for
DNS or the DHCP server is restarted. I know it sounds strange, that's cause
it is VERY strange. What we did was this: after not being able to resolve
names we statically configured the nics and flushed resolver, it works fine,
go back to DHCP assigned DNS flush the resolver cache and nothing resolves(if
it isn't in the DNS server cache). Restart the DHCP server and everything
works right away. Thanks for the reply.
