xhost: unable to open display

Hi! On my new box installed with SuSE 9.2 prof. I got a really critical problem. When I say xhost + in a local shell I get the message: xhost: unable to open display "<name-of-box>:0.0" I also tried to do "xhost <name-of-remote-box>" with the same result. The display name is set correctly (as printenv says). This is very urgent, for we need to open windows from other, remote boxes on this machine. Without that, it can't be used. :-( Any ideas?
