rras & VPN

I have set up vpn and am able to connect to the server via
the Internet. I am using ms-chap v2, pptp, and using an
admin account. I successfully connect and authenticate but
am unable to map drives or gain access to the server. The
server is SBS 2000 and the client is Windows XP home. Can
anyone give me some direction or settings to check?
Anything critical I need to re-check? Anywhere I can go on
the web for more in-depth info?

A VPN connection just gives you IP access. It does not log you in to the
server, and it does not give you name resolution.

If you can ping the server by its IP address, your VPN is working. If
your LAN is running DNS or WINS, you should be able to ping by name. Check
that the client gets the correct DNS and/or WINS address. Can you see the
server's shares using net view \\servername ?

Thanks,
Understand about the VPN connection. I could ping during
one connection but have not been able to in subsequent
connections. My connection details tell me the server IP
and the client IP etc...The server IP is different than
the actual IP, but I figured this is a VPN detail...I try
mapping a drive from command prompt but get error 53. I
left the connection up overnight but still get denied. Is
there a rfc on step by step instructions so I can check my
settings? I have had sporadic success with this in the
past, but it never seems reliable for me. The clinet does
get all the correct info but I don't appear to be
authenticated to the LAN?

To access resources on the LAN (where the VPN server is), you must have
credentials which are valid on that network. Have you tried using the "Log
in using a dialup connection" on the client? This logs you into the domain
as well as setting up the VPN connection.

The IP you see for the server (in the connection details) will be
different from its LAN IP. Like the client, the server acquires a "virtual"
interface and IP to act as the server end of the VPN connection.

Hi I had a problem similar recently when setting up a VPN at a site , This
particular problem was caused because we tested the VPN connection with a
laptop that was normally set for Static IP Address so when it was taken off
of the LAN it kept its IP address which was on the same subnet as the VPN
address it receive so it would try to send it's packets out through there as
it had a higher priority , Disabled the Adapter all worked OK.

My two penneth worth
