Article ID: Q168747 
Creation Date: 20-MAY-1997
Revision Date: 24-MAY-1997 

The information in this article applies to: 

Microsoft Windows 95 
Microsoft Windows 95 OEM Service Release versions 1, 2, 2.1 

SYMPTOMS 
On a computer running Microsoft Windows 95 (all releases) 
using the Microsoft TCP/IP protocol, the following error message 
may occur when certain data is received over the network: 

   Fatal exception 0E at 0028:<address> in VxD MSTCP(01) + 000041AE.
   This was called from 0028:<address> in VxD NDIS(01) + 00000D7C.

After this error message occurs, the computer may not receive further
network data until Windows is restarted. 

CAUSE 
This error message can occur if certain, very specific, 
"out-of-band" data packets are deliberately sent to the 
server during a TCP/IP session.

This issue is resolved by the following updated files for 
Windows 95 (all releases): 

Vtcp.386 version 4.00.0954 (dated 05/20/97) and later 
Vnbt.386 version 4.00.0959 (dated 05/15/97) and later
