Windows XP - Vista Network

I have a home network consisting of a desktop computer with Windows XP SP3
and a laptop with Vista Premium SP2 (Hebrew version).
There is no problem to transfer files from the laptop (Vista) to the
desktop computer (XP) but when I try to transfer files from the desktop
(XP) to the laptop (Vista), I receive the following message:
.....the PC is not accessible, you might not have permission to use this
network resource...etc.etc."
Any help will be greatly appreciated.

I have no problems doing it. But you have to do it insecurely. Just
export as a wide open share and map a drive.

It is also slow, Vista is slow over the network. Don't expect to
utilize 100BT to it's max, Vista throttles network traffic internally,
not allowing one process to fully utilize the bandwidth. The TCP/IP
stack is brain dead. They do this as if Vista could use it all,
everything else suffers. You can show nicely how Vista/Win 7 does this
by switching between 100BT and 1000BT and monitoring the network
utilization. Vista will always keep it 25 ot 50% of the available
resources.

I suspect disk copy works this way, and why it is so damned slow. It
isn't like Linux or UNIX that will allow 100% use of resources and load
share when two operations need the sam resource. I suspect Microsoft
did this as message passing kernals suck in contention situations. 100%
pre-emptive is where it is at which needs a Mac, Linux or UNIX.
