[Samba] Problems with Windows XP pro after initial login to Samba 3.0 server

[Robert Galter]

Question: Does anybody have a solution for this problem?
Problem: Windows XP creates a new user with same name after initial machine
login to Samba domain.  E.G. under Documents and settings the user name:
gilbert existed as a subdirectory with additional subdirectories such as
desktop, startup, MyDocuments, etc.  The following procedure was used in
Windows XP to log the machine into the Samba server:
1. Open System Properties dialog
2. Click Computer Name tab
3  Click command button:  Change.
4. Click Member of Domain radio button
5. Fill domain name of edit field with Samba domain name
6. Click OK - User name/password appears
7. Fill in "root" as user name and "rootspassword" as the password
8. Wait
9. Process completes and then reboot.

At this point a new user has been created:  gilbert.000 .  This new user has
not inherited any of the settings from the original user, i.e.  Desktop is
blank, applications do not launch at startup, installed programs are not in
start menu.  The same set of subdirectories exist off of gilbert.000 but
they are empty.  The original gilbert subdirectory still exists but
gilbert.000 has no access rights to gilbert.  The original gilbert is an
admin user and the new gilbert.000 has no admin rights.  As the new user
without rights, gilbert.000 cannot be changed back to admin.

How do you keep this behavior from happening on Windows XP pro?
How do you correct the problem after it has happened?
