NetBT Event ID 4319 2

[rphips]

I keep getting the 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 the name that is in conflict."

The error seems to be generating from the fact that I dual NIC cards running in my server.

Microsoft says to fix this error run the latest patch - Already did

Both NICS are set with a static IP, a subnet mask, default gateway, and DNS lookups

Should I be setting them up differently? I can't unplug one cause them Exchange will not load and AD will not replicate.

Any suggestions.

Duplicate name issue

Symptoms: Event viewer may show Event ID 4320, Event ID: 4319. You may get system error 52 and a duplicate name has been detected on the TCP network.
Resolutions:
1. If two computers on the Network with the same name, use the nbtstat -n command to find out these two computers, for example, using nbtstat -n to check the name and ip of the local computer, and then using nbtstat -a command with the IP address to get the another computer name.
2. If identical username is logging on to multiple computers, the usernames will register with a <03h>, and that may cause the name conflict in the network. Ask the user to log off of all computers and log back on to just one computer.
3. This may be occurred because of inactive or duplicate names in the WINS Database. Go to the WINS server, check the database and delete the inactive or duplicated names.
4. This my be occurred because of a possibly corrupted DHCP database. To clear DHCP related entries or clean out old settings in the registry, delete any .mib files, and then reinstall DHCP.
5. This may be occurred because of conflicting NICs in a Multihomed Computer. To fix this problem, you may want to stop Computer Browser service or uncheck one of Client for MS Network.
6. This may be ocurred because IPCONFIG /ALL returns incorrect host name. To change computer name in the TCP/IP parameters section, run regedit.exe, and locate the HOSTNAME value in the HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip \Parameters, and then edit the string data.

If you do ipconfig /all on the computer, What does it say?
Make sure only one nic is pointing to a primary dns server and default gateway ......

I removed the default gateway and the primary DNS server from the second NIC cards TCP\IP roperties. This seem to work on the Windows 2000 Server but not my 2003 server.
