ARC4 Plugin w/o key + MS-Logon

[egerlach]

I'm trying to run UltraVNC with the ARC4 plugin without specifying a key, and the server is using MS-Logon. However, I'm not getting the MS-Logon prompt, just the prompt for a vanilla VNC password.

Is what I'm trying to do impossible? Thanks!

did you enter a classical password as well you need to have both a classical and mslogon??

I just tried that, and it doesn't seem to work. Have you got it working this way?

I remember, Scovel do not test dsmplugin with mslogon

If you can wait, friday at evening swiss time 23h30
I would try to test between dmsplugin ARC4Plugin.dsm without key and MS-Logon
my test would be realized only between XP pro SP2 and XP Pro SP2
and UltraVNC 1.0.2 at both side.

hope you can wait.

LAN 100 Mbit/s <---> LAN 100 Mbit/s same subnet (internal)
XP SP2 uvnc server 1.0.2 as service and XP SP2 uvnc viewer 1.0.2
ARC4Plugin100.dsm without key at both side


VNC password need authenticate at max 8 caracters (if you added more, authentication always fail) if you have not set VNC password, authentication fail, arc4plugin need to hash VNC password for continue authentication.
then VNC password success, authentication should continue with "Require MS Logon" prompt.

"New MS Logon" require some modification to UltraVNC server side
regedit
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa
change value of ForceGuest=1 --> 0

That work for me.
