Fatal Exception Error Using DHCP

ID: Q158713

The information in this article applies to:

Microsoft Windows 95

SYMPTOMS

When you use Winipcfg.exe to release or renew IP addresses obtained using DHCP, or when you start Windows 95 with the network adapter configured to obtain IP addresses using DHCP, you may receive an error message similar to the following message on a blue screen:

Fatal exception 0E at 0028:C433442B in VXD octk16.sys (01) + 0000342B. This was called from 0028:C003C47C in VXD NDIS (01) + 00000D7C. It may be possible to continue normally.

CAUSE

When you are using the Windows 95 DHCP client, a buffer in memory used to send a DHCP message may be freed before the message has been completely sent. The error occurs when the network adapter driver attempts to access this buffer to send the information on the wire.

RESOLUTION

This issue is resolved by the following updated file for Windows 95 and OSR2, and later versions of this file:


   VDHCP.386  version 4.00.953  dated 11/19/96  27,973 bytes

STATUS
