For Windows NT/2000/XP/2003 workstations that use Novell Client login scripts, a map command in the login script has the same effect as using an explicit map root command. It automatically enables a mapped NetWare subdirectory as a fake root directory. Applications installed in the subdirectory serving as the fake root cannot access directories above that subdirectory.
If necessary, you can disable the map command’s automatic Map Root behavior on Windows by adding SET MAPROOTOFF="1" as the first line in the login script. To create a fake root when the MapRootOff parameter is enabled, the login script must explicitly use the map root command.
For more information, see the Novell Login Scripts Guide.
