Service Controller Query Command??
] qc [ ] [ ]
|Specifies the name of the remote server on which the service is located. The name must use the Universal Naming Convention (UNC) format (for example, \\myserver). To run SC.exe locally, omit this parameter.|
|Specifies the service name returned by the getkeyname operation.|
|Specifies the size (in bytes) of the buffer. The default buffer size is 1,024 bytes.|
|/?||Displays help at the command prompt.|
- The qc command displays the following information about a service: SERVICE_NAME (service's registry subkey name), TYPE, ERROR_CONTROL, BINARY_PATH_NAME, LOAD_ORDER_GROUP, TAG, DISPLAY_NAME, DEPENDENCIES, and SERVICE_START_NAME.
Administrators can use Sc commands to determine the
binary name of any service and find out whether it shares a process with
other services. They do this by typing the following at the command
prompt (where ServiceName is an actual service name):
sc qc ServiceName
The Services.exe program starts all services. To conserve system resources, several Win32 services developed for Windows are written to share the Services.exe process. These services are not listed as separate processes in System Monitor or Task Manager. The same is true of Svchost.exe, a service host process that is shared by many operating services.
There might not be a process for every Win32 service because third-party Win32 services can also be configured to share processes. You can use Sc to get configuration information about these services. If a service does not share its process with other services, however, there will be a process for it in System Monitor when the service is running.
commands can be useful for developers of services because it provides
more detailed and accurate information about services than does
Services.exe, which is included with Windows. Services.exe can determine
whether a service is running, stopped, or paused. Although these tools
are adequate for a debugged application that is running smoothly, the
information they provide about a service being developed can be
misleading. For example, a service that is starting is shown as started
whether it is actually running or not.
Note that Sc implements calls to all Windows service control application programming interface (API) functions. Set the parameters to these functions by specifying them at the command prompt.
Using Sc commands, you can query the service status and retrieve the values stored in the status structure fields. Services.exe cannot provide you with the complete status of a service, but Sc shows the exact state of the service, as well as the last checkpoint number and wait hint. You can use the checkpoint as a debugging tool because it indicates how far the initialization progressed before the program stopped responding. In addition, Sc enables you to specify the name of a remote computer so that you can call the service API functions or view the service status structures on a remote computer.
