You know the IP address of your computer? yes? (if not then ipconfig)

That IP address may refer to two different names. Firstly there is the netbios name - which is what you have when you use explorer to find other computers in your workgroup. Secondly there is the domain name, which is what your computer is called when people try to use standard IP and DNS to find it.

It sounds like you want the second one. You can find this name by doing a reverse DNS lookup of your ip address on your local DNS Server. The dig program is a good way to do this and there exists a script called perldig if you don't have a real dig.

Actually in your case the DHCP/DNS name appears to be 'dhcp-offices8-'.$ip_address where $ip_address is your IP address so why bother doing anything more complex?
