netsh Command

NetSh. exe is a configuration tool that now adds the basic network diagnostic features provided by older NetDiag. exe sh is a command-line scripting utility that permits administrators to display or modify the network configuration of a computer that is currently sh provides a scripting feature that allows you to run a group of commands in batch mode against a specified sh can also save a configuration script in a text file for archival purposes or to help you configure other *****n the netsh command from the Cmd. exe prompt and change to the context that contains the command you want to use. The contexts that are available depend on which networking components you have installed.

openfiles Command

Openfiles. exe is used to view the list of connected users and files in use per share on a computer. The openfiles command permits the administrator to make queries, and displays or disconnects open files or files opened by network users. This command also enables or disables the system's Maintain Objects List global flag. This can be done on a local, query, and disconnected basis.

pagefileconfig Command

Pagefileconfig. vbs retrieves the current page file's size or sets a new page file size. The pagefileconfig command enables an administrator to display and configure a system's paging file Virtual Memory settings. The optional settings permit the administrator to create, change, delete, and query related page file sizes.

powercfg Command

PowerCfg. exe enables power management. The powercfg command enables an administrator to control the power settings on a system. The syntax is

[View full width]

Powercfg [/list | /query name | /create name | /delete name | /setactive name | /change

settings | /hibernate [on|off] | /export name [/file file name] | /import name [/file

file name] | /?]

Table A.13. powercfg Command Options
Option	Qualifier	Description
/list or /l		Lists the names of existing power schemes.
/query or /q		Displays the configuration of the specified power scheme. If no name is specified, the configuration of the currently active power scheme is displayed.
/create or /c		Creates the specified power scheme. The new scheme is created with the properties of the currently active scheme.
/delete or /d		Deletes the specified power scheme.
/setactive or /s		Activates the specified power scheme.
/change or /x		Changes settings of the specified power scheme. Additional switches specify the changes as follows: /monitor-timeout-ac minutes turns the monitor off after the specified number of minutes when the system is operating on AC power. A value of 0 will disable the timeout. /monitor-timeout-dc minutes turns the monitor off after the specified number of minutes when the system is operating on DC (battery) power. A value of 0 will disable the timeout. /disk-timeout-ac minutes turns the hard disks off after the specified number of minutes when the system is operating on AC power. A value of 0 will disable the timeout. /disk-timeout-dc minutes turns the hard disks off after the specified number of minutes when the system is operating on DC (battery) power. A value of 0 will disable the timeout. /standby-timeout-ac minutes puts the computer in standby mode after the specified number of minutes when the system is operating on AC power. A value of 0 will disable the timeout. /standby-timeout-dc minutes puts the computer in standby mode after the specified number of minutes when the system is operating on DC (battery) power. A value of 0 will disable the timeout. /hibernate-timeout-ac minutes saves the contents of the computer's memory to disk and turns off the computer after the specified number of minutes when the system is operating on AC power. A value of 0 will disable the timeout. /hibernate-timeout-dc minutes saves the contents of the computer's memory to disk and turns off the computer after the specified number of minutes when the system is operating on DC (battery) power. A value of 0 will disable the timeout. /processor-throttle-ac [none | constant | degrade | adaptive] selects the dynamic throttling policy to be used if your microprocessor supports processor performance state controls when the system is operating on AC power. The desired dynamic throttling policy is selected with one of four additional switches: ·  none causes the microprocessor to operate at the highest performance state at all times. ·  constant causes the microprocessor to operate at the lowest performance state at all times. ·  degrade causes the microprocessor to operate at the lowest performance state, and further reduces performance by applying stop clock throttling as the system battery drains. This option is typically used when the computer is operating on battery power and is therefore seldom used with /processor-throttle-ac. ·  adaptive modifies the performance state dynamically based on the demand the system puts on the microprocessor. /processor-throttle-dc [none | constant | degrade | adaptive] selects the dynamic throttling policy to be used if your microprocessor supports processor performance state controls when the system is operating on DC (battery) power. The desired dynamic throttling policy is selected with one of the four additional switches listed under /processor-throttle-ac.
/hibernate or /h		Turns the hibernation feature on or off. Hibernation timeout is not supported on all systems that support hibernation.
/export or /e		Exports the specified power scheme to a file. If no file name is specified, the default is scheme. pow. This parameter supports the following parameter: /file file name
/import or /i		Imports the power scheme from the specified file. If no file name is specified, the default is scheme. pow. If a scheme with that name already exists, it is replaced with the new one. This parameter supports the following parameter: /file file name
/numerical or /n	Requires you to specify the power scheme using its numeric identifier rather than its name. Use this switch in combination with the /query, /delete, /setactive, /change, /export, and /import commands.
/globalpowerflag or /g [on | off] /option: [batteryicon | multibattery | resumepassword | wakeonring | videodim]	Turns the global power flag features on or off. Use the first switch to indicate whether to turn the feature on or off.
/option:		Is mandatory, and is followed by the name of the feature you are turning on or off. There are five possibilities: batteryicon enables or disables the battery meter icon in the notification area. When this flag is cleared, the battery meter icon is not displayed. multibattery enables or disables multiple battery display in the system's Power Meter. resumepassword enables or disables the requirement that the user supply a password when the system resumes from standby or hibernate. wakeonring enables or disables Wake on Ring support. videodim enables or disables support for dimming the video display when the system changes from AC power to DC (battery) power.

Print Scripts

Print scripts manages printer services, drivers, and queues. The scripts that are most valuable to administrators include:

·  Prndrvr. vbs adds, deletes, and lists printer drivers.

·  Prnjobs. vbs pauses, resumes, cancels, and lists print jobs.

·  Prnmngr. vbs adds, deletes, and lists printers or printer connections in addition to setting and displaying the default printer.

·  Prnport. vbs creates, deletes, and lists standard TCP/IP printer ports in addition to displaying and changing port configuration.

·  Prnqctl. vbs prints a test page, pauses or resumes a printer, and clears a printer queue.

regfind Command

sc Command

SC. exe starts and stops and manages Win32 services. The sc command communicates with the Service Controller and installed services. SC. exe retrieves and sets control information about services. It is used to test and debug service programs. Administrators can use service properties stored in the registry to set the control for how service applications are started at boot time and run as background processes. Batch files can be used to call various SC. exe commands to automate the startup or shutdown sequence of services. SC. exe provides capabilities similar to Services in the Administrative Tools item in Control Panel. SC. exe options cover boot, config, continue, create, delete, description, failure, getdisplayname, getkeyname, interrogate, lock, pause, qc, qdescription, qfailure, query, queryex, querylock, sdset, sdshow, start, and stop.

setx Command

Setx. exe allows environment variables to be set with batch files. The setx command establishes the environment variables in the local or system environment without requiring programming or scripting. Setx also establishes the values of registry keys and writes them to text files. The syntax is
