Problem with multi-homed system

Hi,

I've extended my server machine (W2k Server, computer name "Serv") by
implementing a second NIC in order to utilize a second computer as print
server. But the new configuration kills me: Ping only works on x.x.x.1, DHCP
service shows a fix IP of x.x.x.2, DNS service only reacts on x.x.x.1, I
can't login to my server from the second computer (W2k Pro, computer name
"Cli"). Whenever I want to login to the server's domain at Cli login dialog
I get an error message saying that the domain either is invalid or not
available. On the other hand, if I want to access Cli from Serv's Windows
Explorer using \\Cli\ I get an error message saying that the "login server"
is not available at the moment...

Please, can someone help me? I wasn't aware that multi-homing is that
difficult.

I want to decide which NIC to use for my LAN. The other NIC is supposed to
connect to the Internet using Dial-Up. Accordingly, I want to configure
DHCP/DNS to work on the first NIC only ("Binding..." in DHCP/DNS don't
actually seem to have any effect). I'm using Active Directory.

Thanks for any help!!

Multihoming isn't difficult.

With only partial IP information, I can only give a generic comment. The
IP addresses on each card must be on a seperate subnet.

Hello Rob,

the addresses are: 192.168.190.1, 192.168.190.2

For my testing I've only connected the inbound cable to the server. But Ping
only works if I put the cable into NIC #1. If I plug it into NIC #2, the
destination host is unreachable.

I assume there is no hardware error so far.

TIA,
Axel Dahmen

They should be in different subnets, right now they are not.

Hi Marina and Rob,

just for the sake of my curiosity: Why do they have to be different? What's
the reason Ping doesn't work on my second NIC when they are on the same
subnet? And the others? I'm very keen to know to avoid further configuration
problems.

Thanks for enlightening me!

Regards,
Axel Dahmen

Because you're using the 2nd nic to connect to the external world. That's
why they have to be on a different subnet.

????????? 8-0
Sorry, but I don't understand, I'm afraid... Internal/External connection is
supposed to be my concept, yes, but I haven't implemented any of this yet.
So far, both NICs are not dedicated at all. I'm going to use Dial-Up (ADSL)
which uses a different IP address on the NIC anyway for the time of
connection. I didn't create a dial-up connection yet. I just have two
sibling NICs, and when I plug the cross-link cable from my second computer
into one NIC, Ping works, but if I plug it into the second NIC, Ping doesn't
work. What if I'd connect a third computer, let's say a notebook, to this
second NIC. It shouldn't route, but it should still connect.

I'm baffled. Thanks for enlightening me.

TIA,
Axel Dahmen
