What is the method you use to map drives in XP Mode?
Have you tried to map drive by Use the Net Use command?
You could have a try:
1. Click Start, and then click Run.
2. In the Open box, type cmd.
3. Type net use x:\\computer
name\share name, where x: is the drive letter you want to assign to the shared resource.
If there are any errors in the process, please let us know.
Hope it helps.
