DOCUMENT:Q136458 23-MAR-2000 [winnt] TITLE :NetBIOS Datagrams Sent to Group Names Are Not Broadcast PRODUCT :Microsoft Windows NT PROD/VER:: OPER/SYS: KEYWORDS: ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft TCP/IP-32 for Windows for Workgroups ------------------------------------------------------------------------------- SYMPTOMS ======== NetBIOS applications that send datagrams to group names may fail to work correctly with the TCPIP-32 version 3.11b release. CAUSE ===== When a NetBIOS application sends a datagram to a group name over the TCP/IP protocol stack, it is normally sent to a broadcast address. In version 3.11b of the TCPIP-32 stack, datagrams sent to group names are sent to a specific host address rather than a broadcast address. STATUS ====== Microsoft has confirmed this to be a problem in TCP/IP-32 for Windows for A supported fix is now available, but is not fully regression-tested and should be applied only to systems experiencing this specific problem. Unless you are severely impacted by this specific problem, Microsoft recommends that you wait for the service pack release containing this fix. Contact Microsoft Product Support Services for more information. Microsoft does not recommend implementing this fix at this time. Contact Microsoft Product Support Services for more information on the availability of this fix.
