Read the Samba-HOWTO-Collection.pdf that ships with Samba-3. There is a
chapter on policy management and one on desktop profiles. In there you
will find the registry keys that must be manipulated so that folders like
"My Documents" can be stored on a network share. This manipulation of
registry keys can be done using an NTConfig.POL file that is stored on the

Use of Roaming Profiles without such provisions is the root cause of the
bad experience people on this list have reported. It is definitely NOT
advisable to operate with large profile capacities such as what you are
attempting to do. I have seen desktop profiles as large as 1.5GB! Transfer
of profiles that large over a 100Mb/s network is close to insanity. The
Samba-HOWTO-Collection.pdf provides information that allows you to take

The solution to long profile load times is NOT to disable roaming
profiles. You realise, of course, that by disabling roaming profiles
critical user data will end up being stored on the workstation where it
will not be backed up!

See above comments. Read the documentation. If it is not clear, or you can
not understand it, tell me. I want to make certain that the documentation
is useful and helpful. Please tell me what problems you have that are not
sufficiently addressed in the documentation so I can fix it.

You can get control of your windows network environment only by using
policies to control what users can do on their deaktops, and by using
appropriate profile configurations. MS Windows does NOT do that
automatically in any network configuration - you need to be proactive
about it.
