GUI console are also available using the headless console. This includes starting the system and performing system-recovery tasks. Emergency Management Services consists of components that are standard features of Windows Server 2003, and to which console redirection functionality has been added. Emergency Management Services also includes a management console that is unique to it: Special Administration Console (SAC). You access this console from a headless system using terminal emulation software such as telnet, PuTTY, and HyperTerminal. When SAC is active, it displays the SAC prompt: SAC>. SAC provides a set of commands you can use to perform a number of management tasks that help return the system to a normally functioning state: • restart - Restarts the server. • shutdown - Shuts down the server. Do not use this command unless you can be physically present at the computer when you are ready to restart it. • T - Lists the processes and threads that are currently running. • K - Ends the given process. PID is the process identification number you specify. • L - Lowers the priority of a process (and any associated child processes) to the lowest possible level. • M - Limits the memory usage of a process (and any associated child processes) to a specified number of megabytes. MB is the number of megabytes you specify. Lowers the priority of a process (and any associated child processes) to the lowest possible level. • lock - Restricts access to Emergency Management Services command-prompt channels. • I - Sets or views the IP address of the server. If no parameters are passed, this command lists IP information. You can display or set the IP address, subnet mask, and gateway of a given network interface device by providing the network number, IP address, and subnet information. To do so, use the following format: I • crashdump - Manually generates a stop error message and forces a memory dump file to be created. A stop error is a serious error that affects the operating system and that could place data at risk. The operating system generates an obvious message, a screen with the stop error, rather than continuing on and possibly corrupting data. Also called a fatal system error. • cmd - Creates Windows command-prompt channels. To use a command-prompt channel, you must provide valid login credentials. You must log in to each command-prompt instance. Press ESC+TAB to switch back and forth between the command prompt channels and SAC. If a command prompt channel becomes unresponsive, use the K (end) command to close it. You can then open another command-prompt channel. • D - Dumps the kernel log. • ch - Lists all channels. • F - Switches between showing processes only or processes and threads in output from the t-list command. • T - Lists the processes and threads currently running. • P - Pauses t-list command output at a full screen of output. • R - Raises the priority of a process and associated child processes. • reg_add - Allows registry edits from the SAC. TIP: To list all available SAC commands, enter ? or help at the SAC prompt. To list the subset of SAC commands available for managing command channels, enter: SAC> ch -? SAC also provides access to the setup logs during GUI-mode setup. Press ESC+TAB to switch between the setup logs and SAC.
