Nortel VPN Router Troubleshooting
• DHCP Server assigns IP addresses to clients
• WINS Server provides a translation of the NetBIOS domain name to the IP
address
• DNS Server provides a translation of the IP Host name to the IP address
• Master Browser is an elected host that maintains lists of all NetBIOS
resources
• Domain Controller maintains a list of all clients in the NetBIOS domain and
manages administrative requests such as logins
• VPN Router terminates tunnels and routes Microsoft networking requests
The following questions and answers are particularly directed toward the WINS
server and browsing issues. These questions and answers can help verify whether
you correctly set up these components.
What needs to be configured on the VPN Router for network
browsing?
In the group profiles, set the values of the DNS server and the WINS server.
Remember that these are inherited values, so that if all subgroups of a given group
use the same servers, it is sufficient to configure them in the parent group.
If these servers are not on a directly reachable subnet from the VPN Router, or
accessible through a default VPN Router, you must configure a static route on the
VPN Router to reach them.
What should be configured on the PPTP or IPsec client?
The client needs the protocols for NetBIOS and TCP/IP configured. NetBEUI is
not normally configured.
Configure a Windows 95 or Windows 98 client so that it is in the correct
workgroup for the NT domains it is trying to reach. For example, if there are
domains named Engineering and Admin, and the client is to use the Engineering
domain, then you must configure it that way.
For PPTP only, you must also select Log onto Network under My Computer
