SYMPTOMS
A problem in Windows NT enables someone with physical access to the console of a Windows NT system where a user is currently logged on and the console is locked to retrieve the first line of text from the logged on user's clipboard. This is done by pasting (pressing CTRL+V) the clipboard contents into the User name field of the Unlock Workstation dialog box. Microsoft has not received any reports of adverse effects as a result of this issue.

Terminal Server connections are not affected by this bug, although the Terminal Server console would be.
