SUMMARY
In Windows 2000, you can use a certificate server to authenticate Layer 2 Tunneling Protocol (L2TP) virtual private network (VPN) connections. If you have a server that has Routing and Remote Access Services (RRAS) configured and has active L2TP ports, you may receive the following error messages in the System event log:

Source: RemoteAccess

Event ID: 20192

Type: Warning

Description: A certificate could not be found. Connections that use the L2TP protocol over IPSec require the installation of a machine certificate, also known as a computer certificate. No L2TP calls will be accepted.



MORE INFORMATION
If you do not intend to use L2TP-type connections, you can eliminate this error message by following these steps:
 * 1) Open the Routing and Remote Access snap-in in Microsoft Management Console (MMC) by clicking Start, pointing to Programs, pointing to Administrative Tools, and then clicking Routing and Remote Access.
 * 2) Expand the appropriate server, right-click Ports and then click Properties.
 * 3) Click WAN Miniport (L2TP), and then click Configure.
 * 4) In the Maximum Ports box, click 0 (zero), and then click OK.
 * 5) When you receive a warning dialog box, click Yes. Then, click OK in the Ports Properties dialog box.
 * 6) Close the Routing and Remote Access snap-in.

Event ID 20192 does not occur on subsequent reboots.
