DOCUMENT:Q238198 10-AUG-2001 [winnt] TITLE :RAS Callback to a Hunt Group Does Not Work PRODUCT :Microsoft Windows NT PROD/VER:winnt:3.5,3.51,4.0 OPER/SYS: KEYWORDS:kberrmsg kbtool ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Windows NT Server versions 3.5, 3.51, 4.0 ------------------------------------------------------------------------------- SYMPTOMS ======== If you use the Callback feature on a Windows NT Remote Access Services (RAS) server to perform a callback to a hunt group number, the callback authentication does not succeed and the connection may be terminated with the following error message: Event ID: 20077 Description: The PPP negotiation is not converging. CAUSE ===== The RAS server uses only one port for a callback (when the Callback Security feature is enabled), and that callback must occur on the same client port that performed the dial-out connection. STATUS ====== This behavior is by design. MORE INFORMATION ================ A hunt group is a group of phone lines in which you are connected to the first number available when you dial, or you receive a busy signal. If you receive a busy signal, you try one of the other hunt groups.
