Source: NetBT - Event ID: 4319

Since I enabled the second NIC on a W2K3 server and gave it a static IP, I am getting an error in System as follow:

Source: NetBT
Category: None
Event ID: 4319
Description: A duplicate name has been detected on the TCP network. The IP address of the machine that sent the message is in the data. Use nbtstat -n in a command window to see which name is in the Conflict state.

There is no other system with the same name or IP. What am I missing?

Thanks.

More info please:
Second NIC on same subnet?
Setting up ISA?
Setting up NLB?

 

[julesNDC]

No NLB
No ISA
and yes, same subnet.

Well the system is seeing itself through the other card that is on the same subnet so it does see another machine with the same name.

 

[julesNDC]

What's the fix, do I even need to fix it?

 

[porkchopexpress]

Why have you got two cards on the same subnet?

Porkchop has a vaild question.

I have seen two nics for redundancy, NIC teaming.

Other problems could occur. If both nics are configured with a defualt gateway, you will have routing issues. Your servers routing table will not no which Interface to use as its default route (0.0.0.0).

Ok, I am using on nic for my Intranet and the other is used for FTP access from outside.

So do I need to remove the gateway on one and change the subnet on the other?

Question - is the Intranet and FTP on seperate subnets (networks) or the same network? That question still needs to be answered. I would like to see the Intranet subnet and FTP(outside) on separate networks. Eg. Intranet (10.0.0.20) private network, FTP Outside (27.25.36.97) or whatever IP your ISP has assinged for your public address.

So do I need to remove the gateway on one and change the subnet on the other?

Depending on how your subnets are configured, you can do one of two things. You can turn the server into a router by using RRAS or you can remove the gateway of the Public NIC (FTP) and manually configure your routing table using the "route" command to do a "route add."

The best solution, which may not describe your environment, is to have a DMZ built and place an FTP server there. But you have not supplied enough information to make that determination.

So...
What is the requirement, what do you want the server to do?
Describe your environment; large, small, or test env.
Describe how your Internet access is set up; Network team using CISCO, DSL, Cable modem, or dial-up?

Just need more to go on...
