Hi. I'm running a Samba server on Ubuntu 6.06, which is the browse master for the LAN. It has some shares, and a Windows XP box on the network also has some shares. Everything worked perfectly with the Ubuntu and XP boxes appearing in the OS X network section, and all public shares being mounted on a Geexbox (Linux-based media player) system. Then I clean re-installed Windows XP. Now when the XP system is turned on, for around 20 minutes the other systems can see it, then it stops appearing in the browse master list. It can be accessed by name or IP, but is not found either via the browse master or broadcast. I found some mention of similar problems online, but no solution. Some of these posts suggest that as of SP2, XP no longer sends announcements to the network, resulting in the browse master dropping it from the list. The XP firewall is disabled, and I'm completely out of ideas. Any help would be much appreciated. Nick.
