Slow file transfer between PCs

[Guest]

Hello,

I have two PCs connectied via a router (which is btw also connected to the
Internet) and I have the following problem: when I transfer files between the
two PCs, the "network utilization" stays at extremely low levels (sometimes
under 1%). However, ping shows perfect connection (<1mS, 0% packet lost).
What could be the problem?

Thanks,
Petros

Copying files with drag and drop or cut and paste is not the most
bandwidth-efficient way to do so, and seeing utilization as you do is not at
all unusual. One would be "ROBOCOPY" (Robust File Copy Utility) from the
Windows Server 2003 Resource Kit. Others can be found via Google.

Thanks for the answer... however the problem is not only related to drag and
drop... it also exists in other cases, for example when a user from the PC-1
plays an mp3 file which is on the PC-2, or when I try to do live streaming
(where you can imagine that the results are terrible).

I am sure that there IS a problem somewhere, because in the past the network
utilization was normally around 60%-70%... If this helps you, the problem
occured after I upgraded my PC and re-installed XP.

Thanks again anyway,
Petros

Cut'n'paste/drag'n'drop aren't all that bad. On my home 100 Mb/s LAN,
I get 70-80% efficiency (i.e., >9MB/s) with XP PCs at each end.

In a mixed (XP/W9x) environment, I get far worse (2-6 MB/s, depending on
which end is XP and which end is executing the copy command).

After you reinstalled Windows, did you also install all the drivers for your
hardware - motherboard, NIC, etc.? If not, you need to do so.

Never get drivers from Windows Update. Get them from:

1. The device mftr.'s website; OR
2. The motherboard mftr.'s website if hardware is onboard; OR
3. The OEM's website for your specific machine if you have an OEM computer
(HP, Dell, Sony, etc.).

Read the installation instructions on the website where you get the drivers.

To find out what hardware is in your computer:

1. Read any documentation you got when you bought the computer.
2. If the computer is OEM, go to the OEM's website for your specific model
machine and look at the specs (you'll be there to get the drivers anyway)
3. Download, install and run a free system inventory program like Belarc
Advisor. The older Aida32 is good for this, too.

If you have installed drivers from Windows Update, you can roll them back:
