Assigning Permissions to Domain Members

When you're a member of a domain, the process is the same, except that you can select people and groups from the domain as well.

When you open the Properties dialog box for a file or folder, click the Security tab, then click Edit and then Add, you don't get the same dialog box that you'd see on a workgroup network. On a domain, it's called the Select Users, Computers, or Groups dialog box. You'll also see this dialog box if you right-click on a folder, click Share, and then select Find from the drop-down menu to the left of the Add button.

Note that the standard location for the objects is your current domain. You can still click the Locations button and select your computer's name (to specify local user and group accounts), or even choose another domain on the network, if others are available.
