It is sparatic at these sites as well, that's why I think it's on their end.

Didn't help I know:)

It shouldn't. This is where the forwarders statement works.

Well, I'm in GT?'s address block and GT? configured it... so if this is true
then I'd better put a call in :)
https://www.pcbanking.washingtonmutual.com is the culprit in question. Our
nameserver can't seem to query theirs, ifns.washingtonmutual.com if my
memory is good. And this is the nameserver holding the afforemetioned
If I use an identical machine in the same address block but outside the
firewall it works fine. So routing is not an issue. Firewall is number one
