Nope try again... Its NOT a DNS issue. I hate to say your clueless... But
you DID insinuate that I am, I kinda resent that... Especially when I've
actually taken the time to look into the problem.... If I was clueless, well
thats another story :)

I've actually rebooted my PC into un*x & NT and I see two different results,
NT doesn't work un*x does. I'd say that its a fairly clear cut case of
Livingston and M$ not playing together like nice little children in this
particular instance... I personally can't blame either one, because it
only happens when the two meet... NT can see other routers, and other
traceroutes can see livingston... where oh where to point the finger...

<sarcasm>
I actually looked for an example, with no reverse, but couldn't find one
reall quick... Its getting harder to look down on people as clueless
idiots for no reverse nowdays... My moral superiority complex is being
hurt.
