sc: Service Control

SC.exe (Resource Kit) Service Control - Create, Start, Stop, Query or Delete any Windows SERVICE. The command options for SC are case sensitive. Syntax SC [\\server] [command] [service_name] [Options] Key server : The machine where the service is running service_name : The KeyName of the service, this is often but not always the same as the DisplayName shown in Control Panel, Services. You can get the KeyName by running: SC GetKeyName <DisplayName> commands: query [qryOpt] Show status queryEx [qryOpt] Show extended info - pid, flags GetDisplayName Show the DisplayName GetKeyName Show the ServiceKeyName EnumDepend Show Dependencies qc Show config - dependencies, full path etc start START a service. stop STOP a service pause PAUSE a service. continue CONTINUE a service. create Create a service. (add it to the registry) config permanently change the service configuration delete Delete a service (from the registry) control Send a control to a service interrogate Send an INTERROGATE control request to a service Qdescription Query the description of a service description Change the description of a service Qfailure Query the actions taken by a service upon failure failure Change the actions taken by a service upon failure sdShow Display a service's security descriptor using SDDL SdSet Sets a service's security descriptor using SDDL qryOpt: type= driver|service|all Query specific types of service state= active|inactive|all Query services in a particular state only bufsize= bytes ri= resume_index_number (default=0) group= groupname Query services in a particular group Misc commands that don't require a service name: SC QueryLock Query the LockStatus for the ServiceManager Database. this will show if a service request is running SC Lock Lock the Service Database SC BOOT Values are {ok | bad} Indicates whether to save the last restart configuration as the `last-known-good` restart configuration Options The CREATE and CONFIG commands allow additional options to be set see the build-in help: 'SC create' and 'SC config' Note the qryOpt options above are case sensitive - they must be entered in lower case, also the position of spaces and = must be exactly as shown. The SC command duplicates some aspects of the NET command but adds the ability to create a service. SC query will display if a service is running, giving output like this: SERVICE_NAME : messenger TYPE : 20 WIN32_SHARE_PROCESS STATE : 4 RUNNING (STOPPABLE,NOT_PAUSABLE,ACCEPTS_SHUTDOWN) WIN32_EXIT_CODE : 0 (0x0) SERVICE_EXIT_CODE : 0 (0x0) CHECKPOINT : 0x0 WAIT_HINT : 0x0 To retrieve specific information from SC's output, pipe into FIND or FindStr e.g. SC query messenger | FIND "STATE" SC QUERY state= all |FINDSTR "DISPLAY_NAME STATE" In the statement above the FIND command will set the ERRORLEVEL as follows ERRORLEVEL 0 = Running ERRORLEVEL 1 = Stopped or Paused The NET START command can be used in a similar way to check if a service is running: NET START | FIND "Service name" > nul IF errorlevel 1 GOTO :s_not_running The service control manager will normally wait up to 30 seconds to allow a service to start - you can modify this time (30,000 milliseconds) in the registry HKLM\SYSTEM\CurrentControlSet\Control ServicesPipeTimeout (REG_DWORD) Some options only take effect at the point when the service is started e.g. the SC config command allows the executable of a service to be changed. When the service next starts up it will run the new executable. Config changes requires the current user to have “permission to configure the service”. Examples: SC GetKeyName "task scheduler" SC GetDisplayName schedule SC start schedule SC QUERY schedule SC QUERY type= driver SC QUERY state= all |findstr "DISPLAY_NAME STATE" >svc_installed.txt SC \\myServer CONFIG myService obj= LocalSystem password= mypassword SC CONFIG MyService binPath=c:\myprogram.exe obj=".\LocalSystem" password="" Watch out for extra spaces: SC QUERY state= all Works SC QUERY sTate =all Fails!
