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?

    Is system prefs > sharing > file sharing turned on? You don't have to add any folders in manually, turning it on should start the AFP server for sharing your filesystem. Accessing it using an admin password will allow access to the whole volume.

    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?

    It could be that you have internet sharing enabled on one of your Macs - system prefs > sharing > internet sharing or perhaps you have a network extender that isn't in repeater mode.



    Your ISP provides you with a single IP address. Your router uses a NAT in order to translate the single address into multiple IP addresses. If you have a repeater that also has a NAT, it is taking the IP from the first router and creating another set of IP addresses but these can conflict with each other and you don't need the NAT on the second device.



    Check the IP addresses of all your machines, they should all be something like 192.168.0.2, 192.168.0.3 etc



    If the second last number differs on some, those computers are using a different translator from the others.

    I just checked and only file sharing and screen sharing is selected on all Mac's.

    I may have an idea of what the problem is though. I have a comcast cable modem coming into the house which is connected into an Apple Airport Extreme Base Station. Both MBP's are connected to it via Wi-FI and the Mac Pro is connected to it via Ethernet.

    Then I have another ethernet cable going out of it that goes to another area of the house and through a hub it then connects to a Linksys WAPG, a Wireless Access Point.

    The Mac Mini is connected to that hub via Ethernet though and does not connect to the Linksys WAP at this time.

    I tried connecting the Mac Mini to the AEBS via Wi-Fi and the Mac Mini then showed up in the Finder on the Mac Pro but not on the MBP. I selected it and tried to select both screen sharing and file sharing but it timed out each time.

    I'm not sure if this relates to what the problem could be. I went to the System Preferences to look at IP Addresses and noticed the MBP is 10.0.01.195, the Mac Pro 10.0.1.19, and the Mac Mini 10.0.1.200.
