I don't even know the correct vocabulary to use to ask this question, so I'll try to describe it as best I can.
A previous system admin set up our intranet so that you only have to type one word into the browser and it will correctly send you to the correct server.
For example, on Server 1 we have several IIS 6 sites, we'll call them Site1 and Site2. As long as I am logged into the intranet, either by being in the office or using VPN, I can just type 'dev-Site1' or 'dev-Site2' rather than the whole address.
I have now added a third site, but I don't know how to set it up so that typing 'dev-Site3' into the browser will send me to the correct server.
I know how to do this on a local machine by using the hosts file, but I don't know how to do this so everyone on the intranet can also do it.
