IMPORTANT: This article contains information about editing the registry.Before you edit the registry, make sure you understand how to restore itif a problem occurs. For information on how to do this, view the "Restoringthe Registry" or the "Restoring a Registry Key" online Help topics inRegistry Editor.
The Windows NT Resource Kit provides two utilities that allow you to createa Windows NT user-defined service for Windows NT applications and some16-bit applications (but not for batch files).

Instrsrv.exe installs and removes system services from Windows NT andSrvany.exe allows any Windows NT application to run as a service.
To create a Windows NT user-defined service, perform the following steps:
  1. At a MS-DOS command prompt(running CMD.EXE), type the following command:

    path\INSTSRV.EXE My Service path\SRVANY.EXE

    where path is the drive and directory of the Windows NT Resource Kit (i.e., C:\RESKIT) and My Service is the name of the service you are creating.

    C:\Program Files\Resource Kit\Instsrv.exe Notepad C:\Program Files\Resource Kit\Srvany.exe
    NOTE: To verify that the service was created correctly, check the registry to verify that the ImagePath value under
    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\service name
    is set to point to SRVANY.EXE. If this is not set correctly, the service will stop shortly after it starts and return an Event ID 7000 "The service name failed to start."

    WARNING: Using Registry Editor incorrectly can cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk.

    For information about how to edit the registry, view the "Changing Keys And Values" online Help topic or the "Add and Delete Information in the Registry" and "Edit Registry Data" online Help topics in Registry Editor.

    NOTE: You should back up the registry before you edit it.
  2. Run Registry Editor (Regedt32.exe)and locate the following subkey:

    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\<My Service>
  3. From the Edit menu, click Add Key. Type the following and click OK:

    Key Name: Parameters
    Class : <leave blank>
  4. Select the Parameters key.
  5. From the Edit menu, click Add Value. Type the following and click OK:

    Value Name: Application
    Data Type : REG_SZ
    String : <path>\<application.ext>

    where <path>\<application.ext> is the drive and full path to the application executable including the extension (i.e., C:\WinNT\Notepad.exe)
  6. Close Registry Editor.
By default, a newly created service it configured to run Automatically whenthe system is restarted. To change this setting to Manual, run the Servicesapplet from Control Panel and change the Startup value to Manual. A serviceset to Manual can be started in one of several ways:
- From the Services applet in Control Panel

- From a MS-DOS command prompt, type the following:

NET START <My Service>

- Use the Sc.exe utility from the Resource Kit. Type the following from a MS-DOS command prompt:

<path>\Sc.exe start <My Service>

where <path> is the drive and directory of the Windows NT Resource Kit (i.e., C:\Reskit).

For more information on installing and removing a user-defined service,please see the Srvany.wri document provided with the Windows NT ResourceKit utilities (i.e., C:\Reskit\Srvany.wri). This document can also be foundon the Windows NT Resource Kit CD in the Common\Config directory.
