You can use a lister layout to open a window with a special size, folder, etc.
There isn't currently any way to turn off the toolbars in a particular window, though. (You can add temporary toolbars to just one window, but you cannot take away the normal toolbars without removing them from all windows.)
If you are just using this window to select an RDP link, creating a menu out of the directory may be a better option. The Go FOLDERCONTENT command can do that. There's an example here.
