Duplicate name detected on TCP Network

I have a Windows 2003 Server acting as an application server for 2 programs.  It has 2 NICs built in.  When I go to the event viewer I keep seeing  this error:

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.

For more information, see Help and Support Center at http://go.microsoft.com/fwlink/events.asp.

So I run the nbtstat -n and this is what I see:

Local Area Connection:
Node IpAddress: [192.1.1.190] Scope Id: []

                NetBIOS Local Name Table

       Name               Type         Status
    ---------------------------------------------
    SERVERNAME    <00>  UNIQUE      Registered
    DOMAINNAME  <00>  GROUP       Registered
    SERVERNAME   <20>  UNIQUE      Registered
    DOMAINNAME  <1E>  GROUP       Registered

Local Area Connection 2:
Node IpAddress: [192.1.1.43] Scope Id: []

                NetBIOS Local Name Table

       Name               Type         Status
    ---------------------------------------------
    SERVERNAME     <00>  UNIQUE      Registered
    DOMAINNAME  <00>  GROUP       Registered
    SERVERNAME      <20>  UNIQUE      Registered
    DOMAINNAME  <1E>  GROUP       Registered

Both IP's are valid and I don't see a conflict.  How do I get rid of the error?  I first searched and found several similar problems but none of the solutions appear to work.  We are not running WINS on this domain.

You have the two nics on the same network.  You need to make sure that the nics are not on the same network or you will get the duplicate name error.  

If you want to place the server using multiple nics on the same network, you should enable nic teaming.  In nic teaming the two nics will work together under a virtual ip address.

or you can disable one of these nics.  If you disable one of these nics, you problem will go away.
