I have WS A with LAN and Wireless connection to different subnets. LAN
is primary connection. I ping WS A from from WS B and it resolves to
primary LAN IP, if the LAN connection goes down , I flush my DNS on WS
A and ping WS B and it now picks up the Wireless IP. What in DNS tells
my workstation that the Wireless IP is up and not the LAN? Because WS
A has 2 NIC's, when I do a ping, does it do a round robin for which IP
is up and running?

thanks

Yep, it performs a Round Robin. More reason to never multihome a DC. It
recks havoc with DNS registration and causes inconsistent results and other
numerous issues. You've only experienced some of them. If you need to
multihome a DC, you must pick the primary NIC and disable NetBIOS, DNS reg,
GcIpAddress, and the LdapIpAddress on the NIC. How? There are numerous steps
involved including multiple registry changes to alter a DC functionality. If
I were you, I would simply team the NICs and get a cheapo or more expensive
router if you are offering NAT. If simply trying to offer services on two
subnets, allow the infrastructure routers to route traffic.

If you would like to see the steps and what's involved in detail, I can post
them.

Ace,
it's actually the Workstations that have dual NIC's in them. What
seems to be happening now is when the Workstation boots up, since the
wireless NIC registers last , all traffic is passed through it. I need
to find a way for the workstation to bootup and register the LAN NIC
last, any ideas?
