Hello! Is it nessesary to have a CAL for each user even if they are just accessing a share on the server through windows explorer. They are not actually logging on to the domain at boot but obviously would need to enter a username and password to view the share. This is basically to get over the 10 user share restriction on Windows XP. The clarify, we need say 20 people to access a file share on the network, but do they all need a cal for the server, even if the machine isnt part of the domain (domain wont exist, it wont be a controller)?.
