Event ID 20262 — RAS Connection

Updated: December 16, 2008

Applies To: Windows Server 2008 R2

red

A server running Routing and Remote Access provides two different types of remote access connectivity: virtual private networking (VPN) and dial-up networking. VPN is the creation of secured, point-to-point connections across a private network or a public network, such as the Internet. A VPN client uses special TCP/IP-based protocols called tunneling protocols to make a virtual call to a virtual port on a VPN server. In dial-up networking, a remote access client makes a nonpermanent, dial-up connection to a physical port on a remote access server by using the service of a telecommunications provider, such as analog phone or ISDN. In contrast to dial-up networking, VPN is always a logical, indirect connection between the VPN client and the VPN server over a public network, such as the Internet.

Event Details

Product: Windows Operating System
ID: 20262
Source: RemoteAccess
Version: 6.1
Symbolic Name: ROUTERLOG_UNRECOGNIZABLE_FRAME_RECVD_COID
Message: Cannot recognize initial frame received on port: %1. The line has been disconnected.

Diagnose

The remote access connection must have permissions through dial-in properties of the user account and remote access policies. In addition, the credentials of the remote access client (user name, password, and domain name) must be validated by the remote access server.

This error might be caused by the incorrect configuration of one of the following:

  • Connection settings
  • Credentials of the remote access client

Check connection settings

  • Match all of the conditions of at least one remote access policy.
  • Grant remote access permission through the local user account (set to Allow access). Or, you can grant remote access permission through the domain user account (set to Control access through NPS Network Policy) and the remote access permission of the matching remote access policy (set to Grant access).
  • Match all of the settings of the profile.
  • Match all of the settings of the dial-in properties of the user account.

Check the credentials of the remote access client in Windows or RADIUS

  • If Windows is used as the authentication and accounting provider, the remote access server uses native Windows functions to validate the security credentials of the remote access client (typically, the remote access user's user name and password) and access the remote access client's user account dial-in properties.
  • If RADIUS is used as the authentication and accounting provider, the remote access server acts as a RADIUS client and sends the user's credentials and other connection settings to a RADIUS server. The RADIUS server validates the credentials of the remote access client, authorizes the connection attempt, and stores remote access connection accounting information.

 

Resolve

Configure remote access dial-in

To perform these procedures, you must be a member of the Administrators group, or you must have been delegated the appropriate authority.

Follow these procedures in the order in which they appear until the problem is resolved.

Configure remote access user properties

To configure remote access user properties:

If the remote access server is part of a Windows Server 2008 or Windows Server 2003 domain:

  1. Click Start, click Administrative Tools, and then double-click Active Directory Users and Computers.
  2. In the console tree, click Users (console tree location: Active Directory Users and Computers/domain name/Users).
  3. In the details pane, right-click a user name, and then click Properties.
  4. On the Dial-in tab, under Remote Access Permission (Dial-in or VPN), click Allow access, Deny access, or Control access through NPS Network Policy, and then click OK.

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\RasMan\PPP\Parameters\NegotiateTime

Note:  The default value is 150 seconds. Changes to the registry setting will not take effect until the Routing and Remote Access service or Internet Authentication Service (IAS) are restarted.

Caution:  Incorrectly editing the registry might severely damage your system. Before making changes to the registry, you should back up any valued data on the computer.

Review the remote access service error code

There is not enough information available in the Routing and Remote Access service event message to provide a recommendation for resolution of the problem. If you continue to get this error, contact Microsoft Product Support Services. For more information, see http://go.microsoft.com/fwlink/?LinkId=52267.

For more information about remote access service error codes, see article 163111 in the Microsoft Knowledge Base (http://go.microsoft.com/fwlink/?LinkID=91455).

Correct the mismatch in client and server configuration parameters

Possible resolution:

Check that the remote access client connection is configured with the same connection parameters as the remote access server. For example, Microsoft Challenge Handshake Authentication Protocol (MS-CHAP) version 1 is not supported in the Windows Vista operating system. MS-CHAP version 2 should be used instead because it provides better security. However, Network Policy Server (NPS) supports and can be configured to use MS-CHAPv1 or MS-CHAPv2. There is a potential mismatch in this case with authentication protocols in the client and server configuration parameters. In this case, on the client computer running Windows Vista, change the authentication protocol configuration parameter from MSCHAPv1 to MSCHAPv2, and attempt to re-establish the connection.

Check the authentication protocols

To perform this procedure, you must have membership in Administrators, or you must have been delegated the appropriate authority.

To check authentication protocols:

  1. Open Routing and Remote Access. Click Start, click Run, type rrasmgmt.msc, and then press ENTER.
  2. Right-click the server name for which you want to check authentication protocols, and then click Properties.
  3. On the Security tab, click Authentication Methods.
  4. In the Authentication Methods dialog box, select the check boxes for the authentication protocols that the remote access server will use to authenticate remote clients, and then click OK.

Check for packet corruption
