Connects fine. Can ping by IP but not by NetBIOS ???

We have been using our Cisco 3000 VPN Concentator for quite some time and have a approximately 25 - 30 regular users. Most of these individuals connect from home over a highspeed line (cable, DSL, etc.). Thus far, all have been able to log onto the VPN and Domain and then access all network resources (Lotus Notes, AS/400 etc.).

The problem:

A new user is able to connect successfully according to the logs (see below), but when he tries to use any application that requires a NetBIOS name (Lotus Notes, AS/400 etc.) he gets timeouts. He is able to ping all network hosts by IP address, but not by NetBIOS name.

His OS: Windows 2000 SP2

VPN Client Version: 3.5.2(B)

Any ideas as to how this can be resolved?

Thanks in advance,

-Brian

Check the configured timout value. It seems that netbios traffic which is broadcast based does not keep the tunnel up. Adjusting the timer values might help.
