DOCUMENT:Q126560 20-AUG-2001 [winnt] TITLE :Cannot Create NetBIOS Session Over TCP/IP PRODUCT :Microsoft Windows NT PROD/VER::3.5 OPER/SYS: KEYWORDS: ====================================================================== ------------------------------------------------------------------------------- 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, you may receive the following error message: 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.
