Hi, My Samba server worked fine for over 1 year. But after I updated the OS from RH 6.0 to 7.1, I can only see the server in Network Neighborhood (From my Windows 98 client) after I reboot the Linux machine. And I only lasted 10-30 minutes. Then disappeared. I checked the smbd and nmbd, they both run good. using \\server-name, I can see all the shares. So the question is: why I can not see in the Network Neighborhood while the server still running? Please help. Thank you very much in advance. Zhiping
