Err Msg: STOP 0x0000000A Corrupted Data Packet Causes PPTP to Hang in Ndiswan.sys

ID: Q230177

The information in this article applies to:

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

SYMPTOMS

It is possible for a corrupted IP packet received over PPTP to cause your system to bugcheck. This problem only occurs when you run PPTP.

CAUSE

This problem is caused by a corrupted datapacket, where the Frame Length given in the packet header was longer than expected. This caused the code that read that frame to be confused and to corrupt memory, which in turn lead the computer to stop responding (hang). The fix verifies that the Frame Length provided in a packet is not larger than the system expects. Microsoft believes this error to be rare, and the fix to be safe.

RESOLUTION

To resolve this problem, obtain the latest service pack for Windows NT 4.0 or the individual fix. For information on obtaining the latest service pack, please go to:
