Networking delay

I have a series of computers connected to one of my
customers office and all running windows xp professional.
They are all networked and saving information to the main
computer in which is the server. It seems to have short
to a few second pauses everyonce in a while when working
on the server and other computers that are connected to
this network. Is this a problem with Windows XP
Professional, or how can I fix this? I found an article
that is #811169 which resembles the problems that I have.
Is this related? Please contact me at your earliest
convenience.

Thanks,
Kyle Powning
