I'm new to this list . So first all I will express my appreciation for your help. recently I setup samba server on my sun sparc 4 for using as a document center. What I need is a place to put our file , and all of my group could create file of his own , and have the read permission to all file and write permission to the only file he created . Other people out of my group should have only the read permission to all the file. all our client environment is Win95 and I'd like all people can browse my samba server , so I run sambd and nmbd on my samba server . Now it's the question: If I want everyone visit my sabma server through the network neighbor function on the Win95 , I guess I must set up the guest account parameter as pcguest in my sam.conf file , and the write list parameter point to my group. So everyone of the world can visit the samba server , and so do my group , but when my group visit the sabma server through the network neighbor function , he can't get the write permission, because the samba server recognize him as pcguest user , so it doesn't think this user is belonging to my group. This is the problem. How can I let the samba server partition my group from the pcguest user ? So I was using the driver map function to visit the samba server , but after I first mapped a driver to the samba server , the next time starting up the Win95 and visited the mapped driver , I got "permission denied" prompt . So I must unmap then remap the driver to the samba server, it's so bother . Is there a way through it ? another problem is when I open my network neighbor function , usually I can see all the machine , about 200 , in our network , but now sometime I can see the samba server , and sometime I can't see the samba server , sometime I can only see the samba server , other machine on our network all disappear . So strange ! do you have any hints ? thank you for your help again. likun@asiainf.com
