      check the permission settings on the share or the home directory,

        Check your global settings:
    logon home = \\%L\%U\.profile
    logon drive = H:
  and the permissions on the share:
    comment = Home Directories
    valid users = %U
    writeable = yes
    browseable = no
    read only = no
    guest ok = no
    printable = no

  and it can only be mapped automatically if your PC is the domain 
member else you have to go to run and type "\\samba server name" and see 
whether you are able to see your home directory.
  I used to have this error if the smbpassword is different from the 
Linux Local user password.
