Tell the firewalls on the desktop AND the notebook the range of IP addresses that they need to permit (trust) in order for the two computers to communicate. It's the same idea, but different security suites/firewall programs use different terms for it.
I have a home network with a desktop and notebook sharing a printer and internet. Everything worked fine until recently when I couldn't print from my notebook. So I decided to reinstall my printer from my notebook. In the Add Printer Wizard, where I am suppose to browse for my printer, the hour glass symbol stays on forever obviously not able to find my printer. What can I do? (The printer works fine from my desktop and the internet works fine from my notebook.)
