niko:
i used to have the same set up that you have now. i suggest highly to convert to a server (bert arn't you proud of me now?).
The issue is that the terminal desktop that you use as your server is still doing other things as well. It is going to respond slowly. So I was having ping times between the laptop and the "main computer" of up to 30 seconds at times. It just depends on waht is being done on the other computer.
I initally thought something was wrong with my wireless and played with different routers. THe minute i switched over to the server, i instantly had a huge difference.
I would ask other docs in the area of people they used to set up the server. I did mine for very cheaP! it was very easy. the guy spent about 6 hours at my pplace from 4pm till about 10 pm and we set it up and it works great.
the other thing you can god is take that main computer and don't let anyone use it at all. but these computers arn't made to have a bunch of terminals using it at once.
later
Ideally I would like a server too, as I dont like using the AC database computer as a terminal too.
Can I dedicate ANY comptuer as a stand alone server, or do I need to purchase a server specific computer?
Also what is your server set up. I'd like it very cheap too!
