Remote Desktop, encryption?

Archived from groups: microsoft.public.windowsxp.work_remotely (More info?)

When I connect via Remote Desktop to a Windows XP machine, what kind of
encryption is used and where can I find documentation on this?

    RC4, 128 bit keystrength.

    128 bit RC4 - it is enough safe

    The reference below states:

    "Beginning with Windows 2000, administrators can choose to encrypt data
    using a 56- or 128-bit key."

    I can't find any administrative GUI to control encryption when connecting TO
    a Windows XP machine. I know how to do this on a Windows Server 2003
    machine, but not for connections to the Windows XP desktop.

    Can anyone clarify?

    Hey Olav,

    Thanks for your posting here.

    By default, Windows XP Remote Desktop use high (128-bit) encryption to
    encrypt most data transmissions in both the client-to-server direction and
    the server-to-client direction.

    For more information, you may take a look at the following article:

    275727 High Encryption on a Remote Desktop or Terminal Services Session Does
    http://support.microsoft.com/?id=275727

    Hope this helps! If anything is unclear or you need further help, just post
    back to let me know. Have a nice day!

    Thanks & Regards

    Thanks - that's a very useful reference, and gives some additional
    information about why a VPN connection adds to the security of Remote
    Desktop.

    Here's a reference that a great many folks in this group will find
    enlightening:

    http://www.microsoft.com/resources/documentation/WindowsServ/2003/all/techref/en-us/Default.asp?url=/Resources/Documentation/windowsserv/2003/all/techref/en-us/W2K3TR_ts_how.asp

    It is oriented towards Windows Server 2003, which is a more complex case of
    Terminal Services implementation, but the greater part of it is just as
    relevant to XP.

    I'm not coming up immediately with the reference you need about what
    controls encryption levels in the XP client. Part of this relates to server
    settings--if the server is set to require high (128) bit key strength, then
    the client can't contravene that and connect successfullly. There are
    client settings controlled by Group Policy however, and those settings
    should be found in this document, for XP Service Pack 2.
