    Generally by VLAN or completely physically seperate wiring only meeting at the router.

    Ours was always physically sperate until we introduced email years ago when it was changed to be separated by VLAN, now we've gont 1 big flat network split up into multiple vLANs depending on room or building. And one for printers.

    Ours are one integrated domain, so we aren't separated at all.

    Imagine two completely seperate networks - requires lots of switches and cables.
    With vlans the network can be segregated onto different ip networks, but they still use the same switches and cabling.

    Primarys all in one nice big mixture and works darned well if I do say so myself, as for my main place, 1 Domain, but most servers are shared with 2 cards, so we have 2 DHCP, 2 DNS, 2 WINS etc

    Be aware that VLANs aren't a bullet proof security measure. ARP flooding the switch will usually destroy any port tagging you have setup for the duration of the attack.

    Also the data sent within one vLAN doesn't affect the performance of the other vLANs. Theoretically if you set up a server in say, vLAN 2 and imaged all the machine in that vLAN, any computer not in vLAN 2 shouldn't be affected by the traffic.

    Re: How do you seperate your networks. Subnet / Vlan

    We kept our networks seperate until we needed to run SIMS in the classroom. Thought about using trust domain and other options as mentioned on here, but then realised that at the end of the day, the biggest security flaw was staff leaving their PCs logged in in the classroom. Long gone were the days when you could keep SIMS in the office. So we have one big domain for everyone, and we keep the permissions as tight as possible. And we shoot staff who leave themselves logged on. Saves on admin time since you only have to manage the one domain.
