We are relocating where our main fileshare is located as well as where user home directories are stored. Most users have a mapped-drive S that points to our main fileshare. What is the easiest (best) way to make sure that when all users login on the day after the relocation, drive S points to the new location and that their "My Documents" points to the correct location as well? We are using Active Directory with mixed Windows Server 2008, 2008 R2, 2012 R2 servers. All clients are on Windows 7.
