If a PS/2 keyboard or a PS/2 mouse is not connected to a Windows Server 2008-based computer or to a Windows Server 2003-based computer when the computer starts, the following event is logged in the System log:
Event ID: 7026 The following boot-start or system-start driver(s) failed to load: i8042prt
Additionally, the remote console keyboard and mouse are recognized by the server as USB devices. In Device Manager, a black exclamation point (!) on a yellow field appears next to these devices.
This behavior occurs because Windows does not initialize the remote administration key at a setting of 1 if the emergency management console is enabled.
You can safely ignore this event. However, you can work around this behavior. To do this, disable the PS2 service. To have us disable the PS2 service for you, go to the "Fix it for me" section. If you would rather do this yourself, go to the "Let me fix it myself" section.
Fix it for me
To disable the PS2 service automatically, click the Fix this problem link. Then click Run in the File Download dialog box, and follow the steps in this wizard.
Note this wizard may be in English only; however, the automatic fix also works for other language versions of Windows.
Note If you are not on the computer that has the problem, you can save the automatic fix to a flash drive or to a CD, and then you can run the fix on the computer that has the problem.
