Volgens Betanews zit er weer eens een gat in de beveiliging van Windoos 2000. Onderstaand probleem heeft alleen betrekking op Beta 3, niet de nieuwere RC2 builds:
The latest security problem in Microsoft software stems from the popular 'autologin' feature that was first included in Beta 3. Windows creates an autologin account for all users who are not connected to a domain, which includes almost every home user. Usually, there is little security risk unless the malicious user can obtain physical access to the computer. However, if the Telnet server is enabled, a remote user could log in with full access to the computer remotely. Some reports indicate that a remote user could activate the Telnet server with a VBScript code hidden in an HTML document.
