Error message when you try to access a mapped drive that is mapped to a Windows XP-based computer from a Windows Vista-based computer: “System error 5 has occurred”
Consider the following scenario. You map a drive to a Windows XP-based computer from a Windows Vista-based computer. When you try to access the mapped drive from the Windows XP-based computer, you receive the following error message:
System error 5 has occurred.
Access is denied.
This problem occurs if the following conditions are true:
- Both computers are members of a workgroup.
- You do not give the Full Control shared permission to the Everyone group.
- You give the Full Control shared permission to the Administrators group.
Note: This access failure occurs regardless of the NTFS file system permissions that are assigned to the mapped drive.
