How to uninstall L2TP/IPSec NAT-T Update?

  1. I'm having a problem with a computer here...

    It looses connection with the Novell servers quite often and gives the message: "The Reference (handle) is invalid" (loosley translated from Swedish) when I try to access the mapped volumes...

    This computer amongst the others that have problems sit in a separate VLAN on another subnet; going through a firewall to reach the Netware server...

    And I just realized it has the unfamous "NAT-T" update applied (I never put those on any systems due to my bad experience with that update)

    So, I wanna remove this update... OS is WinXPSP1, how do I go about doing this?

    (Note, I've looked for more than an hour via Google now...)

    If the update doesn't create new registry values and/or other configuration files, I guess you could just overwrite the following files manually (from SP1 or whatever might work):

    L2TP/IPSec NAT-T Update for Windows XP and Windows 2000
    The English version of this fix has the file attributes (or later) that are listed in the following table. The dates and times for these files are listed in coordinated universal time (UTC). When you view the file information, it is converted to local time. To find the difference between UTC and local time, use the Time Zone tab in the Date and Time tool in Control Panel.
    Code:
       Date         Time   Version            Size    File name
