DOCUMENT:Q244982 10-AUG-2001 [winnt] TITLE :Radius Authentication Provider Name Limited to 14 Characters PRODUCT :Microsoft Windows NT PROD/VER::4.0 OPER/SYS: KEYWORDS:kberrmsg ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Windows NT Server version 4.0 - Microsoft Windows NT Server, Enterprise Edition version 4.0 ------------------------------------------------------------------------------- SYMPTOMS ======== After you configure a Remote Authentication Dial-In User Service (RADIUS) authentication provider in Microsoft Management Console (MMC), the Internet Authentication service (IAS) may not start and you may receive the following error message: The service failed to start. Please use the NT Event Viewer to examine the application event log for details. The System log in Event Viewer may contain the following entry: The Radius Server / Proxy service terminated with the following error: The parameter is incorrect", and application log is said "An error occurred while processing column 47 of line 5 of file USERS: Address Expected. CAUSE ===== This behavior can occur if the authentication provider name is longer than 14 characters; the configuration utility cannot handle longer names. RESOLUTION ========== To work around this issue, do not use the fully qualified domain name (FQDN) for the authentication provider. Use either the actual server name without including the domain name, or use the TCP/IP address of the authentication provider in the DNS Name box when you configure the RADIUS server in MMC. STATUS ====== Microsoft has confirmed this to be a problem in the Microsoft products that are listed at the beginning of this article.
