Pack 4 (and later) with a Routing And Remote Access Service (RRAS) server that is a member of a Windows 2000 mixed-mode domain, or a Windows Server 2003 answering router that is a member of a Windows NT 4.0 domain that is accessing user account properties for a user account in a trusted Active Directory domain, use the net localgroup Pre Windows 2000 Compatible Access command to verify that the Everyone group has been added to the Pre-Windows 2000 Compatible Access group. If it is not, issue the net localgroup Pre Windows 2000 Compatible Access everyone / add command on a domain controller computer and then restart the domain controller.
For a Windows NT version 4.0 Service Pack 3 (and earlier) RRAS server that
is a member of a Windows 2000 mixed-mode domain, verify that the Everyone group has been granted list contents, read all properties, and read permissions to the root node of your domain and all sub-objects of the root domain.
For PPTP connections using Microsoft Challenge-Handshake Authentication
Protocol (MS-CHAP) and attempting to negotiate 40-bit Microsoft Point-toPoint Encryption (MPPE) encryption, verify that the user s password is not larger than 14 characters.
Verify that packet filtering on a router or firewall interface between the call
ing router and the answering router is not preventing the forwarding of tun neling protocol traffic. See Appendix B, Configuring Firewalls for VPN", for information on the types of traffic that must be allowed for PPTP and L2TP/ IPSec traffic. On a Windows Server 2003 based answering router, IP packet filtering can be separately configured in the advanced TCP/IP properties dialog box and in the properties dialog box of an interface under IP Routing in the Routing And Remote Access snap-in. Check both places for filters that might be excluding VPN connection traffic.
12 Troubleshooting Site-to-Site VPN Connections |
Verify that the Winsock Proxy client is not currently running on the calling
router. You can tell if you have the Winsock Proxy Client installed on your com puter by going to Control Panel and looking for the WSP Client icon. If it is present, go into the properties and disable it so that the VPN can operate. When the Winsock Proxy client is active, Winsock API calls such as those used to create tunnels and send tunneled data are intercepted and forwarded to a configured proxy server. Proxy servers are typically used so that private users in an organization can have access to public Internet resources as if they were directly attached to the Internet. VPN connections are typi cally used so that authorized public Internet users can gain access to private organization resources as if they were directly attached to the private network. A single computer can act as a proxy server (for private users) and an answering router (for authorized Internet users) to facilitate both exchanges of information. A proxy server based computer allows an organization to access specific types of Internet resources (typically Web and FTP) without directly connect ing that organization to the Internet. The organization can instead use pri vate IP network IDs (such as 10.0.0.0/8, 172.16.0.0/12, and 192.168.0.0/16).
L2TP/IPSec Authentication Issues
We provide a typical L2TP log on the companion CD for your use to compare to your own. The most common problems that cause site-to-site L2TP/IPSec connec tions to fail are the following:
No certificate.
By default, site-to-site L2TP/IPSec connections require that the calling and answering router exchange computer certificates for IPSec peer authentica tion. Check the Local Computer certificate stores of both the calling and answering router using the Certificates snap-in to ensure that a suitable cer tificate exists.
