I can see that now, thanks.  Now to go heckle the opendns guys...

But I doubt it will do any good to heckle the verizon techs.  Trained (insert 
laugh track here) MSCIE's probably, us peons can't even tell them the time of 
day.

But I'll switch back to the vz servers just for grins:
[root@coyote ~]# time /usr/bin/smbclient '//not.a.host.zywx/notashare' -U 
nosuchuser -N -Tx /dev/null
Connection to not.a.host.zywx failed (Error NT_STATUS_BAD_NETWORK_NAME)

real    0m0.925s
user    0m0.025s
sys     0m0.002s

And that is more like it.  But I swear it did do it, using the vz servers, at 
least twice before I switched to opendns.

So that settles it, opendns is likely miss-configured.  Not me.  Trouble 
ticket opened.

Everybody can go back to sleep now, sorry I disturbed your naps. :)
