Step 6: Distribute the profile to remote users

Windows Server 2003's Network Access Quarantine Control (NAQC) prevents remote users from connecting to your network with machines that aren't secure.

The profile you just created is made into an executable file that you can distribute to your remote users so that they can run it on their systems automatically, creating a profile without any intervention after that. You have several options for actually getting that executable file to your users.

You can transmit the executable file as an attachment to an e-mail message, or better yet, as a link to the executable file hosted on a web server somewhere. In the e-mail message, you can include instructions to run the file and use the new connectoids for all future remote access. You also can have the executable run as part of a logon or logoff script, but to do that, you need to either have your users log on through a dial-up connection, or wait until the mobile users return to the home network and are connected at the corporate campus to the network.

Regardless of which method you choose to initially transmit the profile installer to your users, you always should place the latest version of the profile installer on a quarantined resource somewhere, so client computers that don't pass your baselining script's compliancy checks can surf to a web site and download the latest version without compromising further the integrity of your network.
