When using the browse feature in Workgroup Manager to add to a computer list, a standard Connect to Server dialog appears. Select the Local option, which uses Bonjour to discover client computers on the network.
Clients that display their media access control (MAC) address in the list can be successfully added to the computer list.
Additional information
The search options, such as Local and AppleTalk, that appear in a Connect to Server dialog depend on which services are enabled in Directory Access (/Applications/Utilities). If AppleTalk is enabled, for example, you will see a list of all the available AppleTalk Zones. If SMB is enabled, you will see a list of all the available SMB Workgroups.
You can disable any service that you are not using to reduce the number of directory service choices in a Connect to Server dialog. Services such as AppleTalk, SLP, and SMB can appear in a Connect to Server dialog. Some other services cannot appear in a Connect to Server dialog. These include Active Directory, BSD Configuration Files, LDAPv2, LDAPv3, and NetInfo.
