Hi I was wondering if it is possible to migrate from a server-less network to one with a server.
So, what do you want to do with your 'server'? Are you going to try and upgrade on of the current clients to a server? (That won't work BTW)
You should just have to install ther server, set it up with what you want it to do (web, file sharing, FTP, telnet, printer sharing, etc.), and then begin to connect your client machines to it... Depending on the size of your enetwork, there shouldn't be too much planning involved. More details...
