VLAN1 - 192.168.1.x - a MS windows 2000 Domain Controller(D.C.), an Exchange Mail server and Firewall Proxy (ISA) also reside here.
VLAN2 - 192.168.2.x
VLAN3 - 192.168.10.x
VLAN4 - 192.168.20.x
All users in VLAN 1-4 needs to login to the D.C. in VLAN1 and access the shared files there and also checking mails from another exchange mail server. ISA Firewall in VLAN1 allows all VLAN users to surf Internet.
Q1) So how to solve the problem of NETBIOS (domain name) in order for all the VLAN users to login to the D.C. in VLAN 1 successfully?
Q2) For inter-VLAN routing, if I have a combination of 3COM switch, Cisco Switch and router,how can I perform the ISL encapsulation ???
Q3) Can I use the same subnet for two different VLAN ?
I may be mistaken, but if you have Win2k Server and Win2k/XP clients, they don't use NETBIOS for locating the DC or resource location. These newer clients rely on DNS for resource location. If you have older NT clients or something, you could use a WINS server. Also as another poster pointed out, you can use the Cisco ip helper-address command to forward certain UDP broadcasts.
