Then something happened, and the network link is broken. I can still see the desktop from the netbook when I view workgroup computers, but when I doubleclick the desktop icon I get the dreaded "Desktop is not accessible. You might not have permission ..." error message.
The desktop is running Norton's firewall, but disabling that does not help the problem. As far as I know, I have done nothing that would break this link, and I'm wondering if an os upgrade might have changed things so that the old method doesn't work.
I'm mystified, and would greatly appreciate any help that might be out there.
