VPN Connects but unable to browse Network HELP!!

Background
We have an SBS 2003 R2 server that has been set up for remote access via
VPN. The server has 2 NICs and sits behind a Netopia 3347NWG router courtesy
of the former Bellsouth. The router has 5 IP addresses that are exposed for
servers and other items. NAT is not turned on on the router. The clients are
all WIN XP SP2.

Problem.
I can connect a computer remotely to the server and ping it via ip address
or FQDN from behind a Dlink DIR-655 or a Dlink WBR-1310. However, when I go
to map a network share or browse the network, I am unable. The Message
returned says to contact the Administrator (thats me) because the server is
not available. But, If I connect at the office via a wireless router that
sits on another of those 5 exposed IP address on the Netopia but not within
the confines of the Servers internal network, I dont encounter an error.

My first guess is a router configuration is not right and I ahve tried a few
things to no avail.

Can anyone help?

Hi:

In general, I recommend RWW over VPN for connecting remotely. If you have a
particular issue that requires a VPN connection, I would appreciate if you
would share.

To use VPN with your SBS you must first run the CEICW and permit that
service to be used.

Then run the RRAS wizard to setup the WAN ports.

These are the second and third wizards on the To Do List in Server
Management.

You must have a router/firewall that has port 1723 forwarded to your SBS and
that allows GRE 47 to pass. Some older devices do not allow this. And the
other hardware related issue is that the SBS ip ranges and the remote ip
range must be different. That is, if SBS is 192.168.16.x internal, and
192.168.100.x external, the remote cannot have the same numbers in the first
three octets.

Are there any specific errors in your event logs, or specific messages that
occur

And as always, I recommend the SBS BPA. Run that and do what it recommends.

Once connected via VPN go to run and type in the specific share like so:

\\server_name\Share_name

If that works it is a good temporary work around.
I have found that a first time vpn connection rarely populates in network
neighbourhood and reults in failed mapped drives.

Maybe I am doing something wrong with WINS?? Anyone know the answer?

Anyway try the above for now.

Liam,

Your suggestions gave me another idea. Open internet exporer and type in the
the server name. Sure enough it worked and I was able to see all of the
shares and map drives to them.

In that sense the issue is solved. However, I am still concerned as to why I
just can't browse the network. It just seems odd that you can do one thing
but not the other.

Yup,

That works too. I have seen this behaviour many times.
Like I said it may be a WINS issue.

Maybe Super Gumby or Merv know the answer.
