It's windows, yes.
DHCP is not in use. Suffice it to say, while it might be a good idea, it's not in use.
No idea about wifi at home, but it is wired at the office (it probably could be wifi, but there would still be the separate network issues without DHCP).
I did consider a simple batch file, but automatic detection to trigger a batch file is less simple. So it would be a manual process.
I might look at this - http://www.eusing.com/ipswitch/free_ip_switcher.htm
It too might be a manual process, but will have a look and see.
