You're much more likely to be able to ping an IP address than you are pinging a 
hostname. After all, /someone/ has to resolve that hostname into an IP address 
for the ping to work at all!

The resolving can be done either (or both) of two ways: You either have an 
/etc/hosts file in the machine that needs to do the resolving or someone on your 
internal network has a DNS resolver. This last is usually your router or 
firewall. If you are all on the same box (a combined BE/FE) then a hosts file is 
usually enough.

192.168.1.101 is either: powered off, disconnected from the network, bad cable, 
bad network configuration so that it's not listening, not mapped (see above) or 
firewalled. Pick one.
