I am now getting a message saying that McAfee is unable to display a map of the PCs and other devices on the network when I attempt to go Manage Network on the machine I used the cleanup tool with. This is intermitten, but when the network map does come up I only see the machine, router, and internet. The two other machines display the network map, and they have two entries for the machine I ran the cleanup on, both gray, one with the McAfee "M" on the monitor.
The two wired machines can still ping the wireless laptop. Neither of the three machines can connect/share however.
I made some progress last night. I realized after my last post that the duplicate computers displaying on the network map was due to the dynamic IP address being changed. From there, I went ahead and trusted those single IPs of each machine on all three machines. I did see a lot of incoming requests that were being denied on the error logs. From there I went ahead and followed the "setup a home or small office network link" and now I have all three machines displaying on the workgroup. The Windows 7 laptop and one of the XP wired desktops are able to share now. Unfortunately I am not able to connect the third machine, where I want to share my printer, as I get the computer is not accessible error message. I still cannot ping the machine either. I have gone back to trying to manage the machine on the manage network screen, but when I try to make the request I do not receive any prompts on either of the machine. It's like I never even make a request. Should I try to reinstall/cleanup McAfee on the machine I am still having problems with (again)?
Not being able to "ping" from the event logs, I started a "command prompt" (Start ---> Run ---> cmd), and issued a "ping" command to both an IP-address and the URL ("www.yahoo.com" and others).
This was done through a Linksys router, connected via cable modem. All nodes were tracked, although the "ping" command is a line-mode function, so no maps produced.
On the Manage Network screen on the two machines that are unable to connect to the wired XP, the machine that they cannot connect to does not have a green check mark.
This is the same machine is the one that I connected to the network first and at the top of the Manage Network screen it does say <computer name's> Network. For the computers that are unable to connect, it does give an "Unknown" status under Last scan, Last update, and Subscription Expiry, but it does list under Permissions that "this computer can manage other computers on this managed network." It does have a Red M on the monitor screen.
