Frustrated

I have WinXP pro (desktop) and WinXP home (laptop) in LAN.

If I transfer data from laptop to desktop, all is fine and system uses >75%
of 100mbit LAN bandwidth.

When I transfer anything from desktop to LAPTOP problems begin,
bandwidth usage is varying between like 0.5 - 2.5% of LAN bandwidth only.

If I set up FTP server on laptop and download/upload data, transfer speeds
are just fine and using >75% network bandwidth.

What might cause these slow transfers to one direction? And how to possibly
fix it?

I've installed latest drivers for network cards without any help for
situation. Any ideas are welcome, thanks in advance.
 
Sounds like an SMB protocol problem. Make sure both cards are set to 100
Full, not auto-sense or auto-negotiate. On the desktop make sure both
"Network Client Digitally Sign Communications" options are set to disabled
in Local Security Policy/Security Options. You can also reset the TCP/IP
stack from the command line by typing "netsh int ip reset resetlog.txt". And
if you are running SP2 try a winsock reset by typing "netsh winsock reset"
from the comand line. Other than that get the latest Windows updates/patches
for both PC's.

WinXP home is patched up to date. XP PRO is not totally (no SP2) because
after installing SP 2 it really do not work at all (not sure what it is, but
I've installed sofar SP2 twice and both time there were problems) :/ So I
have to use SP1 + patches only currently on XP pro.

I reseted TCP/IP stack and WINSOCKs but that didn't help. Also set both NICs
to 100 full-duplex.

I set "Network Client Digitally Sign Communications" disabled from winXP PRO
(desktop) throigh gpedit.msc. IS there way to tweak those settings on XP
home too?

Anyway, I tried what you suggested without any help :/

Weird is that I had other laptop previously networked. It's network for
sending/recieving for BOTH, my desktop and current laptop, worked full speed
without any problems. Only problem seem to be Desktop => (new) Laptop and I
really can't think anything what might cause this. If I transfer data
through FTP, all is fine, if through network, it works dog slow (estimate of
3 minutes for 4.5mb file transfer just few moments ago I tried to check)...

Any further ideas how to fix things are apreciated.
