I think it will.
A printer connection from one PC is counted as 1 connection and a mapped network drive from the same machine is counted as another connection.
I suspect you are busting your 5 connections limit for XP home.
Get one of those server boxes they really are a piece of piss to install and you won't need to worry about number of connections again or have to fiddle around getting account details right. If you want to print to it remotely just set up a queue on your main machine and share it. You shouldn't have any problems with the number of connections after all the other devices are printing direct.
I am sure if you ask nicely someone will have used one recently and can advise which current one is the best for what you want.
They are all of a muchness so if you struggle setting it up post on here and we will talk you through it.
