That was my first thought.  We ended up getting a new hub out of the van
and hooking the server up to that hub on the table which went nowhere. 
Rebooting the server yielded the same results - dhcpd still found the
address already in use.  We then put the server back into the building
network and reset the IP address.  After a reboot dhcpd worked fine.  We
pinged the original IP.  Nothing was there.  I don't know what this was
but it definitely appeared to be something in the server itself to me.

The only thing we changed was the server IP address.  It appears the
last day the server really worked right was three (now four) days ago. 
At least that was when the complaints started and it coincided with when
the log files started to show syslog restarts every 15 seconds or so. 
We haven't changed anything on the server for almost a month and even
then the work was only to install some new software (math blaster or
something) in a shared folder.  I'll look into the underlying network
when I next get out there - we did have a switch go down a couple of
weeks ago in another building.  Possibility I guess.

Thanks for the response.
