I would just like to add that I had this exact problem... both machines having Windows XP Prof SP2 and all patches. I spent about 10 hours total trying to fix it, and low and behold my WIFE found this thread!! Thanks to all... Here was my problem: -The HOST computer had the files/folders that I wanted to see. -The REMOTE computer could not see certain random folders on the host machine when a drive was mapped, regardless of the drive letter, whether or not NETBEUI was installed, or if I used IP address or hostname. The SOLUTION, as found on this site, was: -To uninstall the hotfix 885250 from the REMOTE computer. Uninstalling this hotfix from the HOST computer did nothing. Thanks again to all for this thread... you really helped me out. Best Regards, Jdogg
