question about xwindows

[Robert Falanga]

First let me say that I am quite new at freebsd or any other unix type  
system.
My son helped me set up the xwindows (KDE) on this system. It has worked  
OK for quite a while and then yesterday I was trying to install a printer.  
Evidently I messed something up and now I get the following:
hostname: not found
dd: not found
Couldn't create cookie

I haven't a clue as to what is wrong, would someone help PLEASE?

Thank you,
Bob
