To switch from "pass_security=LANMAN" to "pass_security=NTLMSSP" method 
on the LINUX server.

1) You should be using FacetWin Version 40u (Build 513) or later on the LINUX server.

2) Add or uncommit the "pass_security=NTLMSSP" and comment out "pass_security=LANMAN" 
in the "/usr/facetwin/facetwin.cfg" file.  All of the other pass_security lines should be commented out. 

3) You can use the available NTLMSSP.reg file to set the Windows registry settings.

on their Windows computer.

Run the  "$env:homepath" in a PowerShell window to get the user's home directory path 
to save the file.

powershell.exe -noprofile -executionpolicy bypass -file "$env:homepath\fw_smb_clues.ps1"

4) Reboot the Windows computer.
