"ping beagle" returns the correct IP
The name resolution is done at the /etc/hosts or DNS server level, it has
nothing to do the 'correct box' having the 'correct IP'.
Or being duplicated...
The only way to detect a duplicate IP is by capturing packets and checking
the MAC address. If you knew the MAC address of the box, you can use
'arping' to validate it. 'arping' also has a switch to detect duplicate
addresses, but I'm not familiar with the functionality.

The IP address is the same as before, so I don't think there are any
collisions. IE, the computer name is beagle, and "ping beagle" returns the
correct IP address.
I will try the live cd and mnt option to report back.

Weird that you can ping the box and not see anything at boot.
I'd try to rule out a duplicate IP address (as stupid as it sounds, been
there, done that...)
I'd boot the box with a Debian Live CD, then
.- mount the box Debian partition to /mnt
.- mount --bind /dev /mnt/dev
.- chroot /mnt
And begin typing 'apt-get update/apt-get upgrade' away as necessary.
YMMV...

I used aptitude to upgrade a headless server from Debian stable to Debian
testing. The upgrade did not generate any error messages, but when I
rebooted I could not ssh into the box (connection refused) nor do I get
any
output on a monitor I attached to the box (no signal). Apache does not
appear to be running either on the box (could not connect to the box). I
can successfully ping the box.
Any suggestions on how to fix this this server would be greatly
appreciated!
Thanks,
Mark
