NCB_CALL Using Group Names Fails on TCP/IP-32

 Last reviewed: September 9, 1996
Article ID: Q121532
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

When certain applications (for example, ICL TeamOFFICE, a groupware communications application) run on a Windows for Workgroups 3.11 workstation, connections with a Windows NT version 3.5 or Windows NT version 3.1 server cannot be created when the 32-bit stack is in use. With the older 16-bit TCP/IP stack, connections with both Windows NT version 3.5 and Windows NT version 3.1 are possible.

CAUSE

The problem only occurs if the applications attempting to communicate with each other are using NetBIOS group names. If unique NetBIOS names are used, the problem cannot be reproduced.

STATUS

Microsoft has confirmed this to be a problem in TCP/IP-32. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.

ICL TeamOFFICE is manufactured by a vendor independent of Microsoft; we make no warranty, implied or otherwise, regarding this product's performance or reliability.
