Please mention the Operating System and version of both computers. It is especially important to be specific if Microsoft, IBM or Sun (aka Oracle) are involved.

How big are the files? If small files work, this is very important.

Can you describe the route the data takes from one computer to another, complete with line speeds on each leg and any obstacles like firewalls?
There is a whole difference between downloading via the Internet from Australia and two computers on the same LAN.

All this might save posters asking lots of irrelevant questions.

The most common cause of these symptoms is where one or more or the computers has been set to autonegotiate line speed with a switch and has been re-plugged (or whatever) without a reboot such that the line speed has dropped to say 10 Mbits/sec Half Duplex. The fix is to always hard set LAN speeds on both the server and the network component ... and to never re-plug with the power on!

Other common causes are: cabling fault; hardware fault; WAN fault; duplicate IP address; wonky firewall; bad Name Server; flapping routing; Cisco "Jumbo Packets".

I have fixed this sort of problem and achieved dramatic performance and reliability improvement by lowering the block size to avoid multi-block transfers across mixed-manufacturer network components.

Depends on what you have on your systems.
