Can't access desktop--ZA Problem

Howdy. For years I've had my desktop and then a wireless laptop which was
able to access some files on my desktop.

All of a sudden, it can't find the network path.

When I disable Zone Alarm from the laptop, it works fine. I probably did do
a ZA upgrade recently but I'm not sure.

I still seem to have addresses listed in the Trusted Zone, but I'm not sure
if they are correct. It's been many years since I set it up.

Any suggestions/guidance would be appreciated.
