Multiple-Processor Server Hangs When Receiving a Connection Request from a RAS Client

ID: Q242594

The information in this article applies to:

Microsoft Windows NT Server version 4.0
Microsoft Windows NT Server, Enterprise Edition version 4.0

SYMPTOMS

A multiple-processor server may stop responding (hang) when it receives a connection request from a Remote Access Services (RAS) client. This behavior may occur with Microsoft Windows 95 Dial-Up Networking (DUN) 1.3 and Windows NT 4.0 Workstation clients.

CAUSE

This behavior occurs because the Routing and Remote Access Services (RRAS) server locks and is unresponsive after a period of time. The Microsoft Virtual Private Networking Adapter (NDISWAN) requests a spin lock, but the lock is already held.

RESOLUTION

To resolve this problem, obtain the latest service pack for Windows NT 4.0. For additional information, please see the following article in the Microsoft Knowledge Base:
