    My knowledge of networking is limited. I've been asked by a friend to help get DSL working on a small office network. Currently, each of 5 PC's are networked via a hub and have static IP addresses assigned to them. These are the only PCs on the network.

    Question 1: Why would someone set up a network this way? Is there a benefit to assigning each PC its own IP?

    I ask because I have all my PC's at home connected using a common WORKGROUP name and everything works great. I didn't have to assign IPs.

    The DSL tech said that the office is set up as a peer-to-peer (?) and all he could do was run the lines and set up the router, but he couldn't touch the PC's.

    Question 2: Depending on the answer to question 1, can't I just set up the office network using a workgroup name and let the router assign IP addresses via its internal DHCP - just like my home network?

    Question 3: If yes to number 2, how do I change the existing PC setups to go from assigned IP's to on-the-fly DHCP via the router?

    Sorry fo so many question, but I don't want to screw up her office network. At least now all the computers can talk to each other. I need to be sure I can set things back in case of trouble. Thanks in advance!

    Unless you can change stuff like the default gateway and DNS servers, you will not get the Internet access to be functional. You can leave the IP addresses static if they like, but you'll have to change the other parameters.

    FWIW, all of your machines in your network also have a unique IP address, you just let DHCP do the work and assign them.

    If you are allowed to change the IP scheme, my advice would be to set all the machines to automatically obtain the IP and DNS addresses after connecting the router's LAN port to a port on the hub.
