multiple network cards

Microsoft Windows 2000 professional upgr...

Specs: Windows XP
I have a HP Proliant 510 computer with windows 2000 professional. I have 2 network cards, one with IP 10.10.10.1, which is connected directly to another computer with IP 10.10.10.2. The other network 172.16.X.X, both cards indicate that they are enable, but what happens is when the 10.10.10.2 computer comes up his ethernet bridge sees the IP 172.16.x.x, instead of the network card he is directly connected to (10.10.10.1). How is this possible, the reason is I am trying to send messages from 10.10.10.2 to 10.10.10.1, but it can't because he sees the 172 IP address instead, by the way the 172 IP is DHCP. Do I need to configure the routing table? If you have an answer please email

What's about the output of an ipconfig /all of the machine that has the ip address 10.10.10.2 ?
The whole configuration like ip, netmask, dhcp, dns and default gateway is necessary for us to help you.

"the IP is 10.10.10.1 "

kazumi68 it helps if you supply ACCURATE information.

I wrote
"post an ipconfig /all from the 10.10.10.2 pc"

see the difference? I want to understand how 10.10.10.2 can see 172.16.X.X. We start with what 10.10.10.2 lists for interfaces and ips

the proliant pc has 10.10.10.1 with subnet 255.255.0.0 it also has an fibre ethernet card with IP 172.16.X.X subnet 255.255.0.0

the power pc (which i called as another pc) has IP 10.10.10.2 and subnet 255.255.0.0 and has no default gateway

No DNS, no default gateway, no static route, no second network interface?

Why don't you simply post the ipconfig /all output.
All the IPs are from private network ranges.
So nothing to worry about when posting it.

no it doesn't have default gateway or static route and no second network interface, it is just the power PC and the proliant, the network card with172.16.X.X. has DHCP in which is connected to another network. the funny thing is if I remove the fiber cable, the card has no connectivity and then messages start going to our application in which collects messages over the 10.10.10.1. I reconnect the fiber and the fiber messages come acrosss also, and that is what we want, both message traffic, its just the 10.10.10.2 seems to connect to the 172.X.X first before the 10.10.10.1. should I do a netstat, is it possible that the routing table is screwed up? Is it better to disable the DHCP and put it as a static IP

The 10.10.10.2 can not connect to 172.16.x.x network.
Try to ping from the machine (10.10.10.2) to the machine (10.10.10.1) but try to ping its 172.x.x.x ip address.
You should get only timeouts.

power pc is a processor with a real time OS, it can't be access too do a ping, what i did do is disconnect the 10.10.10.1 which is a point to point to 10.10.10.2, and did a ping from 172.X.X and it did timeo

As you wrote, these two machines are hard wired.
So a LAN cable runs from NIC 10.10.10.1 directly to NIC 10.10.10.2.
So how should it be possible to first see the other NIC (172.x.x.x)?

Are the network cards at the machine (172.x.x.x and 10.10.10.1) in bridged mode?

That's, why we told you to post ipconfig /all.
So that you can't post ipconfig /all for the 10.10.10.2 machine, you should now post it for the windows 2000 machine.
This will show all the network cards in that machine and it's settings.

i told you it is 10.10.10.2 subnet 255.255.0.0, not gateway no dns setup. Do you know what a real time OS is? it is on an power pc chip which has an internal bus connected to a chip which is a ethernet controller. the IP and subnet is the only thing off the processor board. It is a single board,

I do know, what a real time os is.
Do read my last posting again.
I told you, to post the ipconfig /all of the other machine which has 2 NICs inside, to see whether it runs in bridge mode a.s.o.

@wanderer

Yep just right.
The internal network seems much to secure, to post a simple ipconfig /all.

I can't do the support in this way.
There may be another one here, who has the patience and the knowledge to help on this.

As I have stated you cannot do an IPconfig /all on a real time OS, you do a command called NC, this tells you all the IP information IP, subnet default gateway and DNS as I stated the 10.10.10.2 REAL TIme OS has a subnet of 255.255.0.0, no gateway and no DNS.

the computer that has the 10.10.10.1 and the 172.X.X.X for IP Config all has the following

10.10.10.1 has subnet of 255.255.0.0 not default gateway and no default DNS

172.X.X.X is set to DHCP in which has a subnet 255.255.0.0 and no gateway and no DNS, the IP gets pulled of another server.

So when you state it's like pulling teeth, the above information was giving to you. I asked you how to tell if it is in bridge mode, you have yet answered that question
