Some NE2000 Adapters on Windows 95 Cause Disk or Network Error

ID: Q154697

The information in this article applies to:

Microsoft Windows NT Server versions 3.5, 3.51
Microsoft Windows 95

SYMPTOMS

Windows 95 clients accessing data on a computer running Windows NT Server may receive a "Disk or Network error".

CAUSE

Windows 95 clients using certain uncertified NE2000 adapters may drop incoming packets, resulting in session termination.

RESOLUTION

Contact the manufacturer for an updated BIOS or driver. If the problem persists, replace the adapter with one that is certified.

MORE INFORMATION

The network trace given below shows that the client is not responding to LLC Receive Ready Poll frames from the server. Although the server sent the data frames requested by the client, the redirector did not receive them because the network interface card (NIC) dropped the frames. In this instance, the client redirector terminates the connection after 45 seconds (the session timeout value). In other instances, when there are no responses to the LLC RR frames, the server would issue a DISC frame and terminate the connection.
