Lesson Review

Use the following questions to review what you have learned:

1:	What is meant by the term service discovery?
2:	What are some applications that use service discovery information?
3:	What are four protocols Mac OS X can use for service discovery? How do you enable or disable them?
4:	What is the impact of disabling a service discovery protocol? Does it mean the computer cannot use that protocol at all?
5:	Which files should you check for service directory errors?
6:	Can the computer discover SMB servers beyond the local subnet?
7:	What protocol would you use to share files with computers running Microsoft Windows?

A1:	It is the ability of a computer to find out about computers and other devices that offer services on the network.
A2:	One is the Finder, which displays a list of computers you can connect to when you select Connect to Server. Another is Printer Setup Utility, which displays a list of available printers in the Printer List window.
A3:	They are AppleTalk, Bonjour, SLP, and SMB. Use Directory Access to enable or disable the protocols the computer uses for services discovery.
A4:	If you disable a service discovery protocol, Open Directory does not use it for service discovery on the computer. However, other network services may still use the protocol.
A5:	You should check DirectoryService.error.log and DirectoryService.server.log.
A6:	No, SMB browsing in Mac OS X is limited to discovering workgroups and shared computers on the subnet.
A7:	You would use Server Message Block (SMB).
