5. September 18, 2002 Event Viewer The Event Viewer gathers information about hardware, software, and system problems and monitor Windows 2000 security events Application Log –Events logged by applications or programs. Security Log –Records security events such as valid and invalid logon attempts, as well as events related to resource use, such as creating, opening, or deleting files. System Log –Events logged by the Windows 2000 system components.

Can record data about hardware usage and the activity of system services from local or remote computers. Logging can occur manually on demand, or automatically based on a user-defined schedule

7. September 18, 2002 Shared Folders Create, view, and set permissions for shares, including shares on computers running Windows NT 4.0. View a list of all users who are connected to the computer over a network and disconnect one or all of them. View a list of files opened by remote users and close one or all of the open files. Configure Services for Macintosh. This enables personal computer users and Macintosh users to share files and other resources, such as printing devices, through a computer running Windows 2000 Server.

8. September 18, 2002 Services Using Services, you can start, stop, pause, or resume services on remote and local computers, and configure startup and recovery options. You can also enable or disable services for a particular hardware profile. With Services, you can: –Manage services on local and remote computers, including remote computers running Windows NT 4.0. –Set up recovery actions to take place if a service fails, such as restarting the service automatically or restarting the computer (on computers running Windows 2000 only). –Create custom names and descriptions for services so that you can easily identify them (on computers running Windows 2000 only).

17. September 18, 2002 Groups Types (cont.) Points to keep in mind… Local groups on domain controllers have rights only on the domain where they were created. Local groups on Windows 2000 Workstation computers and member servers (non-Domain Controllers) have rights on the computer where they were created. Local groups cannot contain other local groups; they can contain only user accounts or global groups from the same domain or other domains. Global groups contain user accounts from only one domain. They cannot contain local groups or other global groups. Universal groups contain user accounts from any domain. They can contain universal accounts, global groups, local groups, and user accounts.

35. September 18, 2002 Kerberos in W2K Windows 2000 uses Kerberos V for authenticating computers and users between domains The domain controller acts as the KDC (a trusted third party) in mutually authenticating clients to servers in inter- and intra domain communication Secret-key tickets are given to communicating parties
