Just an update.
I have other problems that I'm going to have to get smart on before I can figure out what's going on.
I uninstalled ZAP from the desktop (and there is no ZA on
either laptop, never has been).
But afterward, even with the winxp firewall disabled, I still could not see the desktop computer
from the laptop.
Actually, I can't see it with either laptop.
I can connect to the wireless router, no problem, and connect to the internet, no problem.
Just cannot access the shared folder and shared printer, or even see the desktop in my workgroup on the laptops.
While playing around, I was able to see the desktop on the laptop at some point in my workgroup; but clicking on the desktop icon resulted in an error message about permissions.
Whereas before when I clicked on the desktop computer icon, it would show the shared folder and shared printer, I now get the error message.
As I said above, this all started with the ZAP upgrade last week.
Before, all I had to do to be able to access the desktop from the laptops was add the laptop IP addresses to the trusted zone in ZAP on the desktop (again, no ZA on the laptops).
My problems could be coincidence, and I won't be surprised if it is.
My plan this weekend is to power everything down, including the router, then power on again, and see if it works.
If it doesn't, then I'll have dig in and try and learn enough to have a clue what could be the problem.
If anyone has other ideas in addition
to what's been posted by the others in this thread, I'll be grateful.
