Problem with 2 networks cards and duplicated machine name in netwo

[Guest]

Hi:

My computer have 2 networks card and Windows is detecting duplicate name in
network, duplicate name is between network cards.

I run nbtstat -n and show me that the conflict is between 192.168.0.2 and
192.168.0.11 (ip address of the network cards).

How can I fix this?

If your network mask has them both on the same LAN, that's the reason for
the error. You can have multiple IP addresses on a single card, just use the
Advanced button in the TCP/IP properties. Use of multiple cards is normally
for connecting to 2 LANs (if on the same physical equipment, you would use 2
different netmasks or IP ranges).

Is there any reason why you're using 2 network cards to connect to the same
LAN?

Hi Daniel:

Thanks for your help. Yes I am a reason to use 2 networks cards in same
network. Card 192.168.0.2 provide mail and access to users data. Card
192.168.0.11 provide internet connection for this computer without affect
performance in mail and access to users data. Exist any form to fix without
change mask?

What speed cards are these? Most cards and onboard chipsets created in the
past few years are capable of 100Mbps, so there should be no reason why
you'd have performance issues using just one. As this is an XP newsgroup I
can only assume you're running XP, and therefore you have a 10 connection
limit for file sharing and MS applications, so the chances of getting
anywhere near 100Mbps are remote, especially if the connection these users
access your machine on is over the internet.

If the internet connection doesn't need to be on the same subnet, can you
change the netmask and IP on your internet connection equipment (I'm
guessing it's a router as you're using a non-routable IP address on the NIC)
to a different address range and the second card to match? That's how it
should be setup if you're connecting to 2 networks.
