Hi.
I have Debian Lenny with Virtual Box. Debian has 2 Displays as one big desktop (not clone or 2x Xserver).
It is possible to run VirtualBox in FullScreen on this 2 Displays with use both of it. Current if i try to Start VirtualBox in fullscreen, it starts only at one display, second display show me the debian desktop wallpaper.

Thank you for answering.

Check the manual, there is a section there that describes how to use more than one monitor for the VM. You do need to use VRDP, the normal GUI won't work with it.

I have the connection with VRDP, my problem is that i cant run both RDP clients in Fullscreen. If i start the first connection in fullscreen, then is the second display black and i cant run other session, or douing anythink in Linux

Then you have to find something to work with that. I'm sorry, but I don't have experience with RDP on Linux like this, or VRDP and multiple displays. Check the man page of rdesktop, maybe there is some setting to get a toolbar or something in fullscreen, or escape fullscreen somehow.
As for the second display to be black, are you sure you did what the manual said?

yes, i think if i start the RDP programm in fullscreen, it start in fullscreen on both display, because if i change the display resolution for example 2560x1024 i get the desktop on both displays.
