SUMMARY

You can use Group Policies to lock down a Terminal Server session on a Microsoft Windows Server 2003-based or Microsoft Windows 2000-based computer. With the following settings, even the administrator account will have restricted access. It is highly recommended that you create a new organizational unit instead of modifying the policies on an existing one.

Note The use of these policies does not guarantee a secure computer, and you should use them only as a guideline.

MORE INFORMATION

Use Active Directory Users and Computers to create a new organizational unit (OU). Right-click the OU, click Properties, and then on the Group Policy tab, click New Policy. Edit this policy with the following settings:
  • [Computer Configuration\Admin Templates\System\Group Policy]

    Enable the following setting:
    User Group Policy loopback processing mode
  • [Computer Configuration\Windows Settings\Security Settings\Local Policies\Security Options]

    Enable the following settings:
    Do not display last user name in logon screen
    Restrict CD-ROM access to locally logged-on user only
    Restrict floppy access to locally logged-on user only
  • [Computer Configuration\Administrative Templates\Windows Components\Windows Installer]

    Enable the following setting, and set it to Always:
    Disable Windows Installer


    Note The default setting for Disable Windows Installer prevents any non-managed applications from being installed by a non-administrator. Setting Disable Windows Installer to Always may prevent some of the newer updates from Windows Update from being applied. Therefore, we recommend that you only set Disable Windows Installer to Always if there is a specific need or an identified threat that you must address.

The Dsacls.exe tool
