i recently installed rhl7.1 on a comp in my college lab. samba was installed by default. then i downloaded xsmbrowser which is a GUI for accessing other comps on the lan using samba. i installed it and it ran perfectly on the first day. from then on whenever i run "#samba start" as the root, it gives me the following error: "/usr/sbin/samba: box: command not found Starting SMB services: [OK] Starting NMB services: [OK]" then when i run xsmbrowser, and click on Samba Config, it gives me the following error: "Unable to find Domain Master" so it is not possible to access the lan

any help will be highly appreciated
