IMPORTANT: This article contains information about editing the registry. Before you edit the registry, make sure you understand how to restore it if a problem occurs.

SYMPTOMS

After installing Windows NT 4.0 Service Pack 4, some third-party services may fail to start.


CAUSE

This problem occurs because Windows NT 4.0 Service Pack 4 changes the Services startup order.


RESOLUTION

To correct this problem, contact the third-party software vendor for help in determining which Windows NT services need to be started before the specific third-party service must be started. After these services have been identified, proceed with the following registry modifications.

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" Help topic in Registry Editor (Regedit.exe) or the "Add and Delete Information in the Registry" and "Edit Registry Data" Help topics in Regedt32.exe. Note that you should back up the registry before you edit it. If you are running Windows NT, you should also update your Emergency Repair Disk (ERD).

  1. Run Registry Editor (Regedt32.exe).


  2. From the HKEY_LOCAL_MACHINE hive, go to the following key: 
    
      \SYSTEM\CurrentControlSet\Services\<third-party service>


  3. From the Edit menu, select Add Value.


  4. Add the following: 
    
      Value Name: DependOnService
      Data Type:  REG_MULTI_SZ
      Data:       <svc_name>


    NOTE: <svc_name> Indicates the NT service that is needed to have already been started for this service to start.


  5. Click OK and quit Registry Editor.


  6. Shut down and restart Windows NT.
