Symptom
When using the browse feature in Workgroup Manager to add computers to a computer list, some clients display their Media Access Control (MAC) address, while others do not.
Solution
MAC address information appears for clients that identify themselves via Rendezvous, supplying information such as the MAC address of the built-in Ethernet port and the computer name. You can successfully add these clients to the computer list when browsing.
To see only clients broadcasting via Rendezvous, select the Local option when browsing. This is discussed further in technical document 107674, "
Workgroup Manager: Select Local When Browsing Computers to Add to a List".
Clients that do not display their MAC address information are using another directory service protocol, such as AppleTalk or SMB. These clients cannot be added to the computer list when browsing.
Additional information
Disabling Rendezvous in Directory Access only prevents the ability to discover services via Rendezvous. It does not prevent broadcast via Rendezvous. This means clients with Rendezvous disabled in Directory Access will still appear in the list when browsing to select a computer.
