問題

After you upgrade to or directly install VSE 8.8, the McAfee McShield and McAfee Validation Trust Protection services are stopped. When you try to start them through the services console, you receive a dependency error.

The services appear normal until the system is restarted.

The Event log displays the following:

The McAfee McShield service depends on the McAfee Validation Trust Protection Service service which failed to start because of the following error:

The operation completed successfully.

原因

In some rare cases, the Start DWORD value is missing from the registry keys that control the McShield and the Validation Trust Protection services.

This issue can also occur when mfevtps.exe is cached as untrusted under certain conditions. This action results in the MFEVTPS service and the dependant McShield service being stopped.

解決策

This issue is resolved in VSE 8.8 Patch 8.

VSE 8.8 Patch 16 is the latest patch available from the Downloads tab on the ServicePortal at https://support.mcafee.com/downloads.

NOTE: VSE 8.8 Patch 16 supports all supported Windows operating systems.

回避策

Create the Start DWORD value for each of the required McAfee processes:

CAUTION: This article contains information about opening or modifying the registry.

The following information is intended for System Administrators. Registry modifications are irreversible and could cause system failure if done incorrectly.
Before proceeding, Technical Support strongly recommends that you back up your registry and understand the restore process. For more information, see: http://support.microsoft.com/kb/256986.
Do not run a REG file that is not confirmed to be a genuine registry import file.

Press Windows+R, type regedit, and click OK.
Navigate to the following registry key:

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\
For each of the following sub keys, verify that the Start value exists within the key, and contains the data shown:
- McShield
  Start=2
- mfevtp
  Start=2
- mfehidk
  Start=0
If there is no Start value, right-click a blank space, select New, DWORD value, and name it Start.
Right-click the new Start value, click Modify, and ensure that the Value data is set to the appropriate number shown in step 3.
Restart the system.

回避策

Uninstall VSE 8.8 using Windows Programs and Features or Apps & features (depending on your version of Windows).
Restart the system.
Reinstall VSE 8.8. For details about this process, see the VirusScan Enterprise 8.8 Installation Guide.
