DOCUMENT:Q125916 18-MAR-2000 [crossnet] TITLE :NetBIOS CALL to a Group Name Fails with TCP/IP-32 PRODUCT :Windows for Workgroups and Windows NT Networking Issues PROD/VER::3.11; WINDOWS:3.11 OPER/SYS: KEYWORDS: ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft TCP/IP-32 for Windows for Workgroups, version 3.11 - Microsoft Windows for Workgroups version 3.11 ------------------------------------------------------------------------------- SYMPTOMS ======== After converting a Windows for Workgroups workstation from TCP/IP-16 to TCP/IP-32 for Windows for Workgroups, some NetBIOS based client-server and peer-to-peer applications may stop working. Error messages indicate that the server or partner can not be found on the network. CAUSE ===== NetBIOS applications use names to identify themselves and to address their partners and servers. To establish a connection with a partner, the application makes a NetBIOS CALL request to a particular name, and the protocol resolves the name to a specific machine. When resolving NetBIOS names for CALL requests, VNBT.386 ignores responses from group names. STATUS ====== Microsoft has confirmed this to be a problem in TCP/IP-32 for Windows for Workgroups version 3.11. A fix to this problem is in development, but has not been regression-tested and may be destabilizing in production environments. Microsoft does not recommend implementing this fix at this time. Contact Microsoft Product Support Services for more information on the availability of this fix.
