I have 4 Mac's in my household, 2 MBP's, a Mac Pro ,and a Mac Mini. I can find the Mac Pro and both MBP's on Back to my Mac but the problem is with the Mac Mini.
I am able to see any of the computers from the Mac Mini but the Mac Mini won't show up on any of the computers. This would be the case using Back to My Mac and won't even work on the Finder within the home network. The Mac Mini simply won't show up in the Finder.
I have Leopard on the system with the latest updates and have gone through the settings and can't find anything that is turned off. Any idea what could be causing this?

I assume you know what you are doing with the usual sharing settings so have file sharing enabled in system prefs.

While you're there, check the computer name in the top most box. It's easy enough to accidentally delete your mac's name and sharing won't work without it.

I was just working with System Preferences and think I may have uncovered something.
When I looked in the Mobile Me section for Back to my Mac it said:
"Back to my Mac is turned on but not working properly. More than one device on network provides Network Address Translation (NAT). Try disabling NAT on one of the devices. Of course I have no clue which of the 4 devices this could be and exactly what this is. It also appears Back to my Mac is working on the other 3 Mac's. Any idea how I can solve this?

Check the sharing preferences for all machines. Perhaps one accidentally has Internet sharing turned on. Make sure all sharing preferences match.

I checked and the sharing preferences and everything is the same on all mac's. Any other ideas of what could be causing this?

Are you sure that computer isn't accidentally on a different wireless network?

Maybe that is the problem. The way my home network is set up is as follows:
I have a cable modem going to comcast and that's plugged into my Apple Airport Extreme Base Station. That router then is connected via ethernet to my Mac Pro and then via WiFi to both MBP's
Then I have a Linksys WAP54G WAP plugged into one of the ethernet ports on the AEBS.
I had been using the Linksys for WiFi on the Mac Mini since that was much closer than the AEBS.
After I read your post though I connected it to the AEBS via an ethernet cable. I even connected it via WiFI to the AEBS.
At that time the Mac Mini showed up in the Finder on the Mac Pro. When I tried to connect though for screen sharing or file sharing it timed out and would not connect. It never showed up on the Finder on the Macbook Pro's.
