Driver under Windows 98 Second Edition: Windows 98 Second Edition Problems with NDIS Intermediate Drivers SYMPTOMS ======== On a computer that is running Windows 98 Second Edition and using networking software that is implemented as a Network Driver Interface Specification (NDIS) intermediate driver, one of the following symptoms may occur: The computer may stop responding (hang) while starting up or shutting down. Your network throughput and overall network performance may gradually decrease, sometimes to the point that the computer hangs or becomes completely unresponsive to network requests. CAUSE ===== This problem can occur if the NDIS intermediate driver code is preempted by the operating system when it is not safe to do so. As a result, a "race" or "deadlock" condition may occur, causing the operating system to hang. RESOLUTION ========== A supported fix that corrects this problem is now available from Microsoft, but it has not been fully regression tested and should be applied only to systems experiencing this specific problem. To resolve this problem immediately, download the fix from WWW.MICROSOFT.COM. Search for "Q243199" and follow the link to the downloadpage. 2.3.
