Fatal Exception Error Using DHCP

 * }

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 A version of this file that also resolves this problem is included in the Windows Sockets 2.0 Update for Windows 95. For information about obtaining this update, see the following article in the Microsoft Knowledge Base:

"Q182108 Availability of Windows Sockets 2.0 for Windows 95"

STATUS
Microsoft has confirmed this to be a problem in Microsoft Windows 95 and OEM Service Release 2 (OSR2). An update to address this problem is now available, but is not fully regression tested and should be applied only to computers experiencing this specific problem. Unless you are severely impacted by this specific problem, Microsoft does not recommend implementing this update at this time. Contact Microsoft Technical Support for additional information about the availability of this update.

This issue is resolved in Microsoft Windows 98.

MORE INFORMATION
The fatal exception error typically occurs in the MAC driver, although it may also occur in NDIS itself.

This symptom may occur more frequently with Token Ring adapters using locally administered addresses (LAAs), although it has been reported to occur with Ethernet adapters and without using LAAs.
