With debugging on, I get the following message in log.nmb: Samba is now a local master browser for workgroup WORKGROUP001 on subnet 10.1.255.255 This message lets you think it is allowed to run several LMB's on one subnet when you have different workgroups. I thought you should only run one LMB on one subnet. I am confused now. What is the correct answer? Regards Ruud Huynen
