I am using Parallels 5, running Windows XP SP2 as a guest OS. When I try to access a network shared folder on another Windows machine, I can view files but when I try to copy something I get the message "Cannot copy filename: Access is denied. Make sure that the disk is not full or write-protected and that the file is not currently in use". I have made sure I'm ok on all of those issues (disk is not full, I can write to it, and the file is not currently in use). Read access on the shared folder is enabled, and I can copy the file with no problem to a 3rd windows computer. This happens if I am in the guest OS trying to access the network share, or if I try to use Mac network to copy to the Windows C drive. I have tried this with and without the virus protection installed, with the same result. Any help would be appreciated.
