Damian,
I'm no expert at all but that's a good guess, something I hadn't thought of. I checked and first of all, it reminded me
thatthe windows box is 2000 pro, not xp pro. More importantly, TCP/IP filtering is set to 'Permit All' for all ports
andprotocols. Beyond that, I am running an application server on the windows box with the httpd on the linux box and
thatis working fine.
Thanks,
Bruce
