We have a Windows 2003 domain with several machines (all of these machines are Windows 2003 machines). These machines have each several network interfaces. Each network interface is part of a VLAN. The idea is to split the network trafic in order to improve security and to not merge all the traffic. These machines share directories. For example : MachineA have @IP 10.0.0.1(mask 255.255.255.0), 10.0.1.1(mask 255.255.255.0), 10.0.2.1(mask 255.255.255.0) and this machine shares directories DataShared1, DataShared2, DataShared3 MachineB have @IP 10.0.0.2(mask 255.255.255.0), 10.0.1.2(mask 255.255.255.0), 10.0.2.2(mask 255.255.255.0). From this MachineB, when we type : net use \\10.0.2.1\DataShared3 are we sure that the network traffic goes throught the VLAN 10.0.2.0(mask 255.255.255.0)? If yes : if we can divide the network traffic by this way, can we do the same thing by using a name instead of @IP? And finally, if we can use name, how can we map name and @IP, without using lmhost, or WINS server (we have tried to use DNS server but it doesnt work : we have an error 52)? Thanks for your help.
