    Question One machine out of 5 inacessible

    I have 4 PC's:

    1. Ubuntu 9.10 with wireless.
    2. Windows 7 Machine 1
    3. Windows 7 Machine 2
    4. Windows Vista
    5. Windows Server 2003

    All machines can ping each other by ip and hostname except for the fact that the Ubuntu machine cannot ping or connect in any useful way to one of the Windows 7 machines.

    An attempt to ping it by name:
    Code:
    therms@tc4200:~$ ping -c 5 Sampson
    PING Sampson (192.168.1.3) 56(84) bytes of data.
    From tc4200 (192.168.1.117) icmp_seq=1 Destination Host Unreachable
    From tc4200 (192.168.1.117) icmp_seq=2 Destination Host Unreachable
    From tc4200 (192.168.1.117) icmp_seq=3 Destination Host Unreachable
    From tc4200 (192.168.1.117) icmp_seq=4 Destination Host Unreachable
    From tc4200 (192.168.1.117) icmp_seq=5 Destination Host Unreachable
    As you can see, it knows the correct IP address of Sampson.

    If I attempt to browse it's network share with Nautilus I get a dialog that says:

    Code:
    Unable to mount location
    Failed to retrieve share list from server
    The machine DOES show up when I open the Network file browser, I just can't access it. I can browse all my other windows machines just fine.

    Suggestions for troubleshooting?

    I doubt route -n will provide any earth-shattering information - but verify the Ubuntu machine knows how to get to the W7 box (you mentioned that it can ping all the others...). You hinted that tc4200 cannot ping 192.168.1.3 either?

    192.168.1.117 is tc4200's own IP, but yeah it can ping itself. It can't ping Sampson by name or IP (192.168.1.3).
