Tips when changing license server

If you have to move or transfer your AutoCAD Network License Manager to another server the users have to be pointed to this server as well.
Instead of having to manually update all users LICPATH.LIC file I have a VBScript that runs when the user logs in that solves this.
Example:
On Error Resume Next
Set WshShell = Wscript.CreateObject("Wscript.Shell")
Set WshSysEnv = WshShell.Environment("SYSTEM")
WshSysEnv.item("ADSKFLEX_LICENSE_FILE") = "@SERVER1;@SERVER2;@SERVER3"
