RAS Server Does Not Automatically Disconnect If Client Sends Host Announcement Packets

ID: Q240106

The information in this article applies to:

Microsoft Windows NT Server version 4.0 SP4

SYMPTOMS

When you are using TCP/IP over a Remote Access Services (RAS) connection, a Host Announcement packet from the RAS client causes the RAS server to reset the automatic disconnection timer.

On a Windows NT-based computer, the Announce parameter defaults to 720 seconds (or 12 minutes). On a Windows NT-based RAS server, the RAS automatic disconnect parameter defaults to 20 minutes. If the RAS client is also a Windows NT-based computer, the RAS automatic disconnect timer is reset every 12 minutes, and therefore, the RAS client never times out.

RESOLUTION
