   As M. Plyler said, it looks like the proper subject line for your    
   message should have been "My DHCP server is handing out the same IP    
   address to two different machines.".   
      
   Perhaps your DHCP server cannot tell them apart.  Do they erroneously    
   have the same MAC addresses and names or something?   
      
   Perhaps you misconfigured your DHCP server.  Did you erroneously tell it    
   to map two clients to a single static IP address?   
      
   If your router is your DHCP server, its WWW configuration interface    
   (which you should be able to access from the machine whose network    
   connectivity is working, after all) will tell you what MAC addresses    
   each of its DHCP clients has.
