Quote from C99:
I've set up synergy a few times now without any troubles. Are your computers setup to share files and printers? Do they all show up in (depending on OS) network neighborhood or network places>view worgroup computers? This is usually all the set-up you need. If you can double click another computer and see its shared resources there you should be good to go. Then install synergy on all computers, pick one as the server and follow the instructions. I don't mind helping too if you need it.
Ok, now you have me thinking. I don't have them on a network, XP netorking that is. I just have them on a 4 port router. I believe I have file and printer sharing enabled. So you are saying I need to create a workgroup on XP, one is XP home the other is XP Pro, do I need XP pro on both, and create a work group?
