This is an issue with network management.
Static IPs should be in a range outside the DHCP served IPs.  If yours 
is static and the other is DHCP that should be fixed.

If both were DHCP assigned then the server is having a problem ( may be 
timing out the lease too soon) or is handing out the same IP to 
different machines at the same time. :-(

Also recently noted on this list, in the network config scripts ( 
/etc/sysconfig/network-scripts/ifcfg-eth0 ) it is possible to assign a 
(specified) MAC address for your adapter that may not be its physical 
address.

If different machines are using the same MAC address they will conflict 
and compete since the DHCP server keeps track of the MAC/IP pairs.
