Vpn sous windows 2003

Solution : Verify that the settings of the remote access policy profile aren't in conflict with properties of the VPN server. Cause : The answering router can't validate the credentials of the calling router user name, password, and domain name. Solution : Verify that the credentials of the VPN client user name, password, and domain name are correct and can be validated by the VPN server. Solution : If the VPN server is configured with a static IP address pool, verify that there are enough addresses in the pool.

If all of the addresses in the static pool have been allocated to connected VPN clients, the VPN server can't allocate an IP address, and the connection attempt is rejected. If all of the addresses in the static pool have been allocated, modify the pool.

Solution : Verify the configuration of the authentication provider. Solution : For a VPN server that is a member server in a mixed-mode or native-mode Windows Server domain that is configured for Windows Server authentication, verify that:. If not, create the group and set the group type to Security and the group scope to Domain local. You can use the netsh ras show registeredserver command to view the current registration.

You can use the netsh ras add registeredserver command to register the server in a specified domain. To immediately effect this change, restart the VPN server computer. For more information about how to add a group, how to verify permissions for the RAS and IAS security group, and about netsh commands for remote access, see the Windows Server Help and Support Center. If not, type the following command at a command prompt on a domain controller computer, and then restart the domain controller computer:.

Cause : The appropriate demand-dial interface hasn't been added to the protocol being routed. Solution : Add the appropriate demand-dial interface to the protocol being routed.

For more information about how to add a routing interface, see the Windows Server Help and Support Center. Cause : There are no routes on both sides of the router-to-router VPN connection that support the two-way exchange of traffic. Create routes on both sides of the router-to-router VPN connection so that traffic can be routed to and from the other side of the router-to-router VPN connection.

You can manually add static routes to the routing table, or you can add static routes through routing protocols. For more information about how to add an IP routing protocol, how to add a static route, and how to perform auto-static updates, see Windows Server online Help.

Cause : A two-way initiated, the answering router as a remote access connection is interpreting router-to-router VPN connection. Solution : If the user name in the credentials of the calling router appears under Dial-In Clients in Routing and Remote Access, the answering router may interpret the calling router as a remote access client.

Verify that the user name in the credentials of the calling router matches the name of a demand-dial interface on the answering router. If the incoming caller is a router, the port on which the call was received shows a status of Active and the corresponding demand-dial interface is in a Connected state. For more information about how to check the status of the port on the answering router, and how to check the status of the demand-dial interface, see Windows Server online Help.

Cause : Packet filters on the demand-dial interfaces of the calling router and answering router are preventing the flow of traffic. Solution : Verify that there are no packet filters on the demand-dial interfaces of the calling router and answering router that prevent the sending or receiving of traffic.

For more information about how to manage packet filters, see Windows Server online Help. Cause : Packet filters on the remote access policy profile are preventing the flow of IP traffic. Skip to main content.
