DOCUMENT:Q184832 10-AUG-2001 [winnt] TITLE :Intermittent Name Conflicts with WINS Server PRODUCT :Microsoft Windows NT PROD/VER:WinNT:3.51,4.0 OPER/SYS: KEYWORDS:kbWinNT400sp4fix ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Windows NT Server versions 3.51, 4.0 - Microsoft Windows NT Server version 4.0, Terminal Server Edition ------------------------------------------------------------------------------- SYMPTOMS ======== Your multihomed Windows NT computers may experience name conflicts intermittently and Event Viewer may log the following event: Event ID : 4320 Source : NetBT 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. CAUSE ===== The server service on your multihomed Windows NT computers is not releasing its registered NetBIOS name from your Windows Internet Name Service (WINS) server properly.
