DOCUMENT:Q120752 08-AUG-2001 [winnt] TITLE :How to Diagnose Event ID 4320 or 4319 PRODUCT :Microsoft Windows NT PROD/VER:winnt:3.5,3.51,4.0 OPER/SYS: KEYWORDS:kberrmsg kbnetwork ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Windows NT Workstation versions 3.5, 3.51, 4.0 - Microsoft Windows NT Server versions 3.5, 3.51, 4.0 ------------------------------------------------------------------------------- SYMPTOMS ======== On your Windows NT-based computer, you may receive one of the following event log messages in Event Viewer: Event ID: 4320 Source: NetBT Type: Error Description: Another machine has sent a name release message to this machine probably because a duplicate name has been detected on the TCP network. The IP address of the node that sent the message is in the data. Use nbtstat -n in a command window to see which name is in the Conflict state. -or- Event ID: 4319 Source: NetBT Type: Error 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 check which name is in the conflict state. CAUSE ===== This message is caused when another computer sends a name release message to your computer. The most likely reason for this is that a duplicate name has been detected on the network. MORE INFORMATION ================ Use the NBTSTAT -N command to see the name of the computer in the conflict state. The IP address of the node that sent the message is in the data returned by this command. The following example shows what the data may look like in one of these events: 0000: 00 00 04 00 01 00 54 00 0008: 00 00 00 00 e0 10 00 c0 0010: 00 00 00 00 00 00 00 00 0018: 00 00 00 00 00 00 00 00 0020: 00 00 00 00 00 00 00 00 0028: e7 1a 65 16 Offset 28 is the IP address of the computer requesting name release. To determine the decimal IP address, invert the four hexadecimal numbers and convert them to decimal numbers separated by periods. Using this method, the IP address of E7 1A 65 16 becomes 22.101.26.231. The status column of the NBTSTAT output for the computer in conflict should contain either "Conflict" or "Released." You can run the NBTSTAT -A command with the IP address to get the computer name. NOTE: This error message is generated in many cases due to normal circumstances, and should not be cause for alarm.
