Back before Bring your Own Device was a thing, I was onboarding home computers onto the school network that I was working at.
ROAMER is a utility that aides devices like Laptops to move between 2 networks like home and work. It will detect if you are at work by trying to make a connection to the nominated file server. If it can, it will then map relevant drives, adjust proxy server, home pages and run post logon scripts. If it cannot make a connection to the nominated network server it will assume it is away from the network and then unmap those drives, restore orginal proxy server settings and home page as well as run any away post logon scripts.
