You can change a dll in Windows XP with an older version plus a
registry setting to allow as many concurrent terminal service sessions
as you need. Also, remote desktop is inherently more reliable than vnc
as I have had it crash on me several inopportune times.

Goodmorning,

You are right upon the terminal services but with regards to the user
being "kicked off" this is meer configuration. There are actual RDP
lisences that you can purchase from windows. Many people in a corporate
environment do so. In a single "poor man's" setup with RDP the event you
referred to will occur. Yet again a "poor man's" setup is VNC in most
cases :P Personally I dont use windows that much and definately not RDP!
VNC has done fine for the passing years and I dont see why it wouldnt
for the upcoming years.

Many Thanks,

For the record, Remote Desktop Connection only spawns another

and, I believe, Server 2000). Windows XP runs Terminal Services Lite
and, as such, Remote Desktop Connection used on a Windows XP box will
kick off the user currently logged in. WinConnect XP Server is an
option to get multiple RDP sessions, and I'm sure others know of
better ways (or, at least, I hope so), as WinConnect is not cheap.

Remote Desktop Connection spawns another "virutal desktop" under the
account credentials you specify. This is unlike VNC which simply
connects to the active display of the user currently logged on. If
VNC is running as a system service it still means that you will be
connecting to the Administrator account. If the station is locked
(ALT CTRL DEL) then you will be looking at the same screen that the
user looks at when he looks at the monitor of the workstation.
Disregarding that simply for aesthetic purposes , what you need is a
RDP like connection.

Hey All,

After compromising Windows workstations I am able to gain a remote
GUI via

either Terminal Services, VNC, GetScreen, etc.

However, this remote access gives me access to the user's GUI, which

limits me to using the GUI when they seem to have left for lunch. ;o)

Does anyone know of any way that I can gain an independant GUI so
that I

can use and install GUI software to continue the attack, without
having to worry about whether the user is using their GUI?

All ideas are welcome.


My opinion is that the more programs you install, the more likely you
are to be detected. CLI equivalents should be used instead of trying
to
use GUI interfaces.

That aside, this hack may help you. I've never tried myself so I
cannot
report on it. Just putting it out there for you to try.
