I have 3 machines networked; 2 run Vista Ultimate and the third runs 2K. I often copy files from the 2K machine to the Vista machines using a batch file and Xcopy. After installing SP1 on my Vista machines, I get an "Invalid Drive" error on my batch file when it tries to copy from 2K to Vista. If I reboot the Vista machines, everything works OK for about an hour or so and then the "Invalid Drive" error returns. Any thoughts?
