This option specifies the drive letter on an NT client to which the home directory specified with the
logon
home
option will be mapped. Note that this option will work with Windows NT clients only. For example:
logon home = I:
You should always use drive letters that will not conflict with fixed drives on the client machine. The default is Z:, which is a good choice because it is as far away from A:, C:, and D: as possible.
