W3K DNS,AD,XP
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?

In TCP/IP properties on the Wireless NIC clear the checkbox on the DNS tab
for Register this connections addresses in DNS.
Then the Wireless NIC won't register at all.

Sorry, I misread it thinking it's your DC. Glad Kevin helped you out.

Kevin,
here is a new wrinkle, we have software that uses Reverse DNS, so we
need the wireless registered in DNS. My problem remains having the LAN
connection being the primary connection when both connections are up.
any thoughts?

Are both the Wired and Wireless networks on the same subnet?
If so, create a Bridge between the two NICs.

No, the LAN and Wireless connections are on two differnt vlans, we
want to create two different paths out.

So you mean each one has a different Default gateway?

Kevin,
other then setting up a bridge on my WS to use both cards or
redundancy, which due to being on 2 different subnets I can't do. what
could I do to make the LAN card the preferred network for the WS on
bootup?
