TCP Connection May Drop When Transferring Large Amounts of Data

• Microsoft Windows NT Workstation version 4.0
• Microsoft Windows NT Server version 4.0
• Microsoft Windows NT Server, Enterprise Edition version 4.0
• Microsoft Windows NT Server version 4.0, Terminal Server Edition

SYMPTOMS

When transferring large amounts of TCP data between two computers, the connection may be aborted. This has been observed primarily in multiple vendor networks when interoperating with other operating systems and TCP stacks.

CAUSE

The Windows NT 4.0 TCP stack may get out of sequence. Examination of a network trace shows TCP sequencing and windowing problems. After sequencing is lost, the TCP connection is reset.

RESOLUTION

To resolve this problem, obtain the latest service pack for Windows NT 4.0 or Windows NT Server 4.0, Terminal Server Edition. For additional information, please see the following article in the Microsoft Knowledge Base:

STATUS

Microsoft has confirmed this to be a problem in Windows NT 4.0 and Windows NT Server 4.0, Terminal Server Edition. This problem was first corrected in Windows NT 4.0 Service Pack 4.0 and Windows NT Server 4.0, Terminal Server Edition Service Pack 4.
