The problem is apparently in your DNS resolution. Basically the master browser says that "UPSTAIRS" exists. But when you browse it tries to resolve UPSTAIRS to an IP address...
With the default resolve order, it tries DNS resolution before broadcast. For some reason (I suspect a DNS that answers something where it shouldn't, like OpenDNS) your DNS resolves UPSTAIRS -> 67.63.55.3. That timeouts and fails. If you switch to bcast before hosts then it asks locally on your LAN "who is UPSTAIRS" et gets the right answer. Setting as invalid as your DNS should not answer 67.63.55.3 when you ask for UPSTAIRS. It should either fail to answer or return the IP address of the UPSTAIRS machine. Try "ping UPSTAIRS" to double-check... ** Changed in: samba (Ubuntu) Status: Incomplete => Invalid -- cannot browse samba shares without editing smb.conf https://bugs.launchpad.net/bugs/375593 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to samba in ubuntu. -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
