network won't work @ 100 mbps

Hi

I have a network of 3 pc's.
2 work @ 100 mbps, the third (of course the most used) only works at 10
mbps.
If i switch the network adaptor to 100 mbps and recieve a large file the
network stalls and corrupts the file.
Tried all the hardware; is ok. Must be XP.

Anyone?

Different brand of network cards sometime have problems communicating
with each other. I have two 3Com 905c cards that work great with each other
but if you take one out and put a Linksys in the 3Com will not communicate
at 100Mbps full duplex very efficiently. Transferring large files actually
slows down. The Linksys seems un effected. If I set the 3Com card back to
half duplex transfer speed increases.
My suggestion is try different settings on the card you are having
trouble with. Start with "Hardware Default". There should be an autosense
setting also. If neither are satisfactory try setting it to 100Mbps half
duplex. There are also settings for 10Mbps full and half duplex. Test
with a large file, at least 5MB and see how each setting handles the
transfer. Use Performance monitor and set it to monitor the network
interface, and select Bytes Sent/sec and Bytes Received/sec. You can see
Min-Max and Average speed. The highest average speed is what you are
looking for.

2 things:

1) ensure you have the latest XP compatable drivers for the network card;

2) A common reason for a network to work OK at 10 MBit but become flakey or
fail at 100MBit is an incorrectly wired cable. Is there ANY home-made
cabling between the faulty machine and the switch?

It is essential to wire the cable with a twisted pair for pins 1+2, and
another twisted pair for 3+6.

I tried the cables; even switched them.
Tried more then one networkcard; the built-in (Dell I8100) and an E-tech.
Tried the newest drivers........

I really think it's XP thats bogging me
