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: 20252
Source: RemoteAccess
Version: 6.0
Symbolic Name: ROUTERLOG_AUTH_TIMEOUT_COID
Message: The user connected to port: %1 has been disconnected because the authentication process did not complete within the required amount of time.

Resolve

Reconnect to port or increase the PPP negotiation time

Try to connect to port again. If the problem persists, increase the PPP negotiation time.

In the registry, change the time for the PPP negotiation process to time out. You set the NegotiateTime entry in the following registry subkey:

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.
