Ok,

I found that for all of my boxen that if I connected to 'server' that
I could not connect back via dblink to the original host!

The nslookup worked fine in every case...

'server' is also my local nameserver. I took a flier and rebooted
the rascal and everything started working again :)

Thanks for the hint.
