Syntax

sc [<ServerName>] lock

Parameters

Parameter

Description

<ServerName>

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.

/?

Displays help at the command prompt.

Remarks

  • Locking the Service Control Manager's database prevents any services from starting. Use this command if you want to make sure that a service will not be started after it has been stopped. This will enable you to perform an action (for example, deleting the service) without interference.

  • Using the lock operation locks the Service Control Manager database and then enables you to unlock the database by typing u. You can also stop the process from which you locked the database.

Examples

To lock the Server Control Manager database on the local computer, type:

sc lock
