Can not Create NetBIOS Session Over TCP/IP

ID: Q126560

The information in this article applies to:

Microsoft Windows NT Workstation version 3.5
Microsoft Windows NT Server version 3.5

SYMPTOMS

When you run NET VIEW or NET USE, the following error message appears:

System error 1225 has occurred. The remote system refused the network connection.

A trace of network activity shows repeated pairs of the following messages:

workstation->server: SYN
server->workstation: ACK, RST

The following STOP message may also appear:

STOP 0xc000000A

This problem occurs on servers with very heavy NetBIOS traffic over TCP/IP.

CAUSE

When netbt receives a zero length message, it fails to update the number of bytes left in the transport. As a result, when the connection is later disconnected, it never receives disconnect indication from the transport, leaving the connection unusable. After all connections are exhausted, new connections are not accepted.

STATUS

NETBT.SYS has been modified so that it correctly handles 0 length messages.

Microsoft has confirmed this to be a problem in Windows NT version 3.5. This problem has been corrected in the latest U.S. Service Pack for Windows NT version 3.5. For information on obtaining the Service Pack, query on the following word in the Microsoft Knowledge Base (without the spaces):
