What is a Multihomed DC?

A Multihomed DC is a domain controller with more than one NIC and/or IP address, and/or RRAS installed on it (for VPN, routing, dialup, etc), or with a PPPoE adapter from your ISP's ADSL line.

Multihomed DCs wiill cause numerous issues. The only exception to the rule are SBS servers, but that is a completely different topic which I will not address in this blog, but I can add that even the SBS gurus recommend to single-home it.

It's highly recommended to single-home all DCs and use a non-DC for multihoming purposes. If it's the internet gateway, such as using the DC as a NAT device, not only will the multihomed DC cause AD problems, but you're also exposing the DC directly on the internet. To overcome both of these issues, I recommend disabling the outer NIC and purchasing an inexpensive cable/DSL firewall/router or other type of firewall/NAT device for this purpose. My preference is a Cisco ASA device. There are also less expensive options, such as a Linksys wireless N router for less than USD $150, and there are less expensive models under it. If the hardware device is compromised by an internet attacker remotely, it can't further compromise the rest of the internal network, nor your DC.

If you have a PPPoE adapter installed (such as the WinPoet software from Verizon for ADSL lines), it will cause the same problems, for after all, they are additional interfaces.

network interface controller - сетевая плата короче...

так и в чем проблема с терминами?
