Hi guysI attach a graphic where you can see my network structure. There are 3 LANs in different cities and they're joined by a VPN. Some switches are attached to others switches. Every LAN have 50 workstation more less. The IP ranges are showed in the graphic. My questions are:I decided to use a PDC samba server. Where should I put it? Will I need more than one samba server? Maybe you can send me some links with a similar problem.If I open my network environment (in windows) I only can see workstations in one LAN. How can I see all workstations? Thanks in advance and sorry for my large email and my english.Juan Chipoco --------------------------------- Internet GRATIS es Yahoo! Conexi?n.
