Using Sc.exe and Netsvc.exe to Control Services Remotely

• Microsoft Windows NT Workstation version 4.0
• Microsoft Windows NT Server version 4.0
• Microsoft Windows 2000 Professional
• Microsoft Windows 2000 Server
• Microsoft Windows 2000 Advanced Server

SUMMARY

Windows NT Server 4.0 Resource Kit Supplement 1, comes with two new administrative utilities to work remotely with Windows NT services.

The new utilities are:

• Sc.exe: This tool provides a way to communicate with Service Controller (Services.exe) from the command prompt, to retrieve information about services.



• Netsvc.exe: This tool provides a way to remotely start, stop, and query the status of services from the command line.

MORE INFORMATION

It is possible to use Sc.exe and Netsvc.exe to switch the start value of a service, and to remotely start and stop a service.

Using these resource kit utilities provides the ability to accomplish the registry change and ensure that the change is registered with the Services Control Manager. The Services Control Manager database is updated dynamically when using these utilities, allowing you to change the start values and stop and restart services remotely. Otherwise, the remote modification to the registry will require you to restart the remote computer or to make the change in the Services tool in Control Panel at the remote computer.

For a detailed explanation of the working of Service Control Manager, and the API set used, consult the Windows NT 4.0 Device Driver Kit (DDK), and the Windows NT 4.0 Software Development Kit (SDK).

An example of how to remotely change the start value of the Schedule service to disabled, test it for the disabled option, reset to manual, and then start the services follows.

In the example, the computer running the commands is MYMACHINE. The remote computer is REMOTE1. Administrative rights are required to perform the following commands on the remote computer:

C:\>sc \\REMOTE1 config Schedule start= disabled
[SC] ChangeServiceConfig SUCCESS

C:\>netsvc /start \\REMOTE1 "Schedule"
Error code 1058

C:\net helpmsg 1058

C:\>sc \\REMOTE1 config Schedule start= demand [SC] ChangeServiceConfig SUCCESS

C:\>netsvc /start \\REMOTE1 "Schedule" Service is pending start on \\REMOTE1

C:\>sc \\REMOTE1 qc Schedule [SC] GetServiceConfig SUCCESS
