Debian - Inside local network

I just installed debian and apache and everything is up and running on 192.168.1.102...  However, when i type my domain name inside my local network, for some reason, it keeps trying to hit 192.168.1.103, instead of 102...   Even when i try to ping my domain name inside my local network, it tries to hit .103.  I have no computers on my network assigned with an IP of .103.   When i am outside my network, such as work or some other place, i can get to my website just fine...  When i do type in .102 inside my local network in IE, it does take me to my website/server...   Anyone got any clue?
