I have 2 PC's connected via ethernet crossover cable. The same 2 PCs connect to my wireless network (for internet access) - each PC has it's own wireless network card. Now the problem I'm having is when copying large files from one PC to the other. The LAN connection is about 4 times faster (and more stable) than the wireless connection, so when copying files I always want windows to use that connection. However it doesn't always do this. Sometimes it will use LAN and othertimes wireless. The only way I've found to stop this is to disable "Client for Microsoft Networks" on one of the PCs. Then windows has no choice but to use the LAN connection for local networking.
Is there another option?
