RAS Server Does Not Support the Full NetBIOS 3.0 Specification

• Microsoft Windows NT Advanced Server versions 3.5, 3.51, 4.0
• Microsoft Windows NT Workstation versions 3.5, 3.51, 4.0
• Microsoft Win32 Software Development Kit (SDK), versions 3.5, 3.51, 4.0

SUMMARY

Windows NT Remote Access Server (RAS) supports most NetBIOS 3.0 commands with a few exceptions. Three features are not supported:

• Sessions can only be established with a unique name, not a group name.



• The NCBFINDNAME command is unsupported.



• The first byte of a NetBIOS name must be a non-zero value.

MORE INFORMATION

The NetBIOS support in RAS was designed to support Windows NT redirector over NetBIOS, not to be fully compliant with the NetBIOS specification. A secondary goal was to support the majority of existing NetBIOS applications (like Lotus Notes).

All widely used NetBIOS commands are supported, and the few that are not supported are both uncommon and complex to implement in a RAS context.
