I have recently installed 3.0.10-1.fc3 on a FC 3 server. I am trying to set up a small homenet work with a windows box and a linux/winXP laptop. The network is on a wireless router (though the windows box and server are wired). I seemed to have everything working and was able to mount drives of any of the computers on both of my FC 3 computers. I was also able to map shares onto the windows box. Explorer on the windows box was also seeing the shares from both of the other computers. The only thing that I know I changed was the smb.conf files on both linux systems. I added the following lines: hosts allow = 127.0.0.1 192.168.0.0/24 hosts deny = 0.0.0.0/0 valid users = username1, username2 After doing this, I was no longer able to browse shares on either FC 3 system using explorer on the win box. I was however, still able to use net use x: \\server\share to map drives on windows. The drive access seems to work fine this way. However, it only works for mapping the server and not the FC3 laptop. smbclient //computername/share still works fine both ways between the linux computers. However, I no longer can mount windows shares on the either linux computer or use smbclient //windowscomputer/share or smbclient -L //windowscomputer All of these give me a "protocol negotiation failed" error. I commented out the above lines in smb.conf but still have not be able to get the network functioning as it was before. To add another piece to the puzzle, I booted my laptop in XP and set up a share on it. I can also map drives on the server (though not on the other windows box (error 58 The specified server cannot perform the requested operation) from the laptop in XP. The FC3 server is capable of accessing and mounting shares from the XP laptop, but again the laptop doesn't see the network shares in explore. It tells me: WORKGROUP is not accessible. etc.. The network name cannot be found. Many thanks to anyone who can help me figure this out. Matt
