Additional Information
Home Directory Feature
A special share name, HOME, is reserved for the home directory. The following restrictions apply. If you have:
- Created a share called HOME, you cannot enable the home directory feature.
- When the home directory feature is enabled, you cannot create a share called HOME.
The home directory feature, which can be provided by the Home Directory snap-in, lets you create a single share, called HOME, to which all users connect. You do not have to create individual shares for each user.
The home directory feature simplifies the administration of personal shares and the process of connecting to them by letting you associate a username with a directory that then acts as the user's home directory. The home directory is mapped in a user's profile so that upon login, the home directory is automatically connected to a network drive.
