How to disable 'save password' field in Microsoft ××× client

I need to disable the 'save pasword' field in the Microsoft PPTP ××× client running on XP.  The ××× client was genereated from the Connection Manager Kit on Server 2003.  I simply want the 'save password' option always grayed out.  I have searched the net and tried what everybody says:
                      HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\RasMan\Parameters
                      Value Name: DisableSavePassword
                      Value Type: REG_DWORD
                      Value Data: 1
                   That works great for my DUN connections, but it DOES NOT affect the ××× client.  A regedit would be fine, but I would prefer a group policy fix, I've already looked with no success, if its available that would be great

                   Suggestions?
                   thx

The approach you're using is *supposed* to apply to native MS ××× connectoids created in "Network Connections" in XP.  Here's what I've seen documented:
                                 - You may need to restart Windows or log off and back on for this change to take effect.
                                 - Now when you open a dial-up connection, the dialog, "Save this user name and password for the following users" is grayed out, and you must manually enter both username and password each time you try to connect.

                                 Dumb question: are you *sure* you created the Value as specified, and the value type as REG_DWORD?  Just checking to be sure, since this *should* work.  If you go to the registry and export the Parameters key to a file, the relevant entry should look like this:

                                 [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\RasMan\Parameters]
                                 "DisableSavePassword"=dword:00000001

                                 However, if it's still not working even after these gyrations, here's another approach to try:

                                 CMAK: After you create the Connection Manager Administration Kit (CMAK) package, use flags to modify the .cms file, and then rebuild the package so that the new file is included in the .exe file.

                                 You can use the following flags to hide the checkbox for "save password" for various connections:
                                 [Connection Manager]
                                 HideRememberInternetPassword=1
                                 HideRememberPassword=1

                                 [From the documentation, it looks like the "HideRememberInternetPassword" is the value that applies to the ××× connections -
