Update to Windows 95 TCP/IP to Address Out-of-Band Issue
The information in this article applies to:
- Microsoft Windows 95
- Microsoft Windows 95 OEM Service Release, versions 1, 2, 2.1
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.
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
To install these updated files, follow these steps:
- Download the Vtcpupd.exe file to an empty folder.
- In My Computer or Windows Explorer, double-click the Vtcpupd.exe file you downloaded in step 1.
- Follow the instructions on the screen.
The following file is available for download from the Microsoft Download Center:
