hello everybody,
still I can not get netbios name resolved from a client VPN connection to a 515 PIX firewall and using a radius for authentication. VPN is connecting fine. I am able to ping all internal IP but when I try to search for a computer name to map a drive, it cannot find it. Do I need wins installed?? The internal W2k server has the default gateway pointing to the inside PIX interface. follws the PIX configuration.  (internal ip:192.168.150.0/24, external public:x.x.230.134)

If you can install a WINS server, and add this to your vpdn group config, then problem will be solved, eg:

vpdn group 1 client configuration wins 192.168.150.6

Agree with Tim.
WINS is definately the answer, unless you have Active Directory and mostly XP clients. Then you need Dynamic DNS enabled..
A temporary measure would be to setup a LMHOSTS file (can be on a shared network drive, accessible once the connection is made). Only two entries are really necessary for the domain controller...

You should have configured your RRAS Server to configure DHCP for your VPN Client with the settings for your DNS and Wins Servers.

Control application downtime with dependency maps

Visualize the interdependencies between application components better with Applications Manager's automated application discovery and dependency mapping feature. Resolve performance issues faster by quickly isolating problematic components.

It seems like WINS is the solution. I am able to resolve the names!

To conclude: What king of application do I need to configure on the server in order to have user at home able to login into W2K and have their profile loaded into their home PCs? (Is it actually possible???)
Thanks for your help....

I wouldn't bother doing this.  W2K roaming profiles can run into 100s of Mbs, and you'll only upset people if you send them this much traffic !
The Cisco VPN Client does have a Start Before Logon (SBL) feature though, which means the tunnel is brought up before the user actually logs onto his/her machine at home.  So, in affect, they're on the domain straightaway.

Have them cache their profiles as offline files.
