Question : User drive mapping shows all user folders

I have mapped each users home directory as servername/users/userand  this mapping allowed for the user just to see their own user directory. it worked for several months but now when users click on their u drive they get a whole listing of all the user directories. I have not changed anything. The share permissions are full control for everyone and ntfs permission for user and domain admin only

Any ideas

Answer : User drive mapping shows all user folders

Could you post the command or path, how you mapped the drives?
Are there spaces? Then set the path between quotes
