SYMPTOMS

If your computer runs Windows 95 or Windows 98 for use as a network workstation, it may be possible for a malicious user to acquire your network password. This attack would require that the malicious user have physical access to your computer at some point after you log on to a server or domain, but before the machine had been rebooted. While a program can be used to read the cached password, doing so requires physical access to your computer when it is not protected by a screen saver password and you must be running the Microsoft Client for Microsoft Networks.
