I did it in my last job, called a database (SQL/Server) update job from an HPUX box. I've also called windows executables from AIX and Solaris boxes.
Open a cmd window on XP and type 'rexec', that explains a litte as well.
The limitations, as far as I know them, are:
[li]The windows box has be running the REXEC service[/li]
[li]You can only call console progams, text based programs, on the windows box and they must be able to run without user intervention[/li]
[li]You have to get the .rhosts file entries correct (and don't ask me how to do that because I have to look it up every time

)[/li]
