Telnet and FTP sluggish problem

Hi:

I have connected a computer and the labtop with a hub. The computer is
running on win2000 and the labtop is running QNX 4.25. When the comptuer
accessing labtop, it runs just fine. But when it wants to access telnet and
FTP, it is sluggish and I need to wait for minutes in order for it to
connect. Can you suggest a way to fix this? Thanks.
