Using direct registry edits is an efficient way to administer remote systems in a networked environment. In the instance your network is running NetBIOS and, perhaps, dictated by security requirements, it is necessary to deactivate TCP/IP under Windows Vista, Windows 7, Windows Server 2008 or Windows Server 2008 R2. Modify the requisite registry entries that control the TCP/IP settings. Steps may be expounded to tune TCP/IP as well as disable it for both IPv4 and IPv6.

Skill level:


  1. 1

    Open the Windows registry editor by pressing and holding the "Windows" key while pressing R on your keyboard

  2. 2

    Type "regedit" in the run dialogue and press Enter

  3. 3

    Navigate to the appropriate place in the resource key for effecting IPv4 settings; namely, "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip4\Parameters."

  4. 4

    Right-click on the right side of the registry editor window and select "New" from the menu followed by "DWORD (32-bit) Value"

  5. 5

    Rename the new entry to "DisabledComponents" and then double-click on it to open the value editor where you will assign a value of FF and click the "Hexadecimal" value checkbox

  6. 6

    Disable IPv6 by navigating to the appropriate place in the resource tree; namely, "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip6\Parameters."

  7. 7

    Repeat Steps 4 and 5 for under the IPv6 parameters registry pane to add "DisabledComponents" and assign a value of FF hexadecimal.

    Restart your system to have the new settings take effect.
