Problem description

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.

CAUSE

This behavior occurs because Windows does not initialize the remote administration key at a setting of 1 if the emergency management console is enabled.

WORKAROUND

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

Now go to the "Did this fix the problem?" section.
