Sorry for the confusion. It seems that I do not have a McAfee firewall.
I have the windows firewall AND the firewall in my Belkin router.
When I try to access laptop #1 from the desktop (even by typing the info in my start box) I get the error code 0x80070035.
In July I moved. Prior to that I had 2 laptops and a desktop computer networked so I could print wirelessly from the laptops to the printer that was connected by USB to the desktop. After I moved, I reconnected all of the components and only 1 laptop could print to the printer.
When I tried to connect to the printer, I would get he error 0x80070035. I have spent a great deal of time trying to figure out the issue.
Finally, after setting a static IP address for laptop #1 and opening a port in the firewall on the router, I am able to wirelessly print again. However, I am unable to access files on the laptop from the desktop. Additionally, the network map (which previously had the laptop connected via a dashed line) now no longer has it connected that way. It sits at the bottom of the page with all of the other devices that the computer doesn't know how to categorize.
Really, all I want is for all of my devices to talk to one another like they used to. I don't understand why this has to be so difficult. Gah. One thing to note, prior to the move, my PS3 could access the internet through the router. After the move, I had to do some complicated port opening for it as well. I don't understand why.
