I was able to setup a VPN connection, however I am unable to browse the remote network.

Any ideas / help on how to troubleshoot this?

Do you have internal DNS/WINS servers?
Are they properly identified in the vpngroup config?
Did you use a separate IP subnet for your clients than your local LAN?

Can you paste your config?

You can try adding a LMHOSTS file with domain controller identified...

Sorry, I should have been more specific. I *can* browse to the remote LAN servers via IP address, but not hostname.

Is there a particular part of the config?

LMHOSTS ?

The remote LAN has internal DNS - no WINS.

There is a seperate submet for the VPN clients.

Try adding a LMHOSTS file on your PC. You only need the two entries for the Domain Controller:

Great - thanks

Is there anything I can do to allow the VPN, as well as the normal traffic simultaneously?

Whenever I open the VPN it drops all of my other connections.

Use the split-tunnel acl and only define traffic from your local lan to the VPN client subnet

Example:

   access-list split_tunnel_acl permit ip <local lan> mask <client subnet> mask
  vpngroup split-tunnel split_tunnel_acl

OK, looking good! But now when I have my connection established, and another user connects my connection is dropped.

That's not good...
How many IP addresses are there in your VPN address pool?

Thanks for you help!! If I had more pts I would certianly assign them :)

For the IP pool, I used: 10.99.99.0 - 10.99.99.255

On another note, adding this to the config seems to have aced my existing PIX-to-PIX config :o

nat (inside) 0 access-list no_nat <-- that was changed to: nat (inside) 0 access-list 101
nat (inside) 1 0.0.0.0 0.0.0.0 0 0

coudl I have just added it as:
nat (inside) 2 access-list 101?

Thank goodness for backups.

I'd have to see your complete config, but I'll try to explain
<you can always buy points>

You need multiple entries in your nat 0 acl. Combine both the VPN clients and the remote site LAN-LAN vpn:

   access-list 101 permit ip <local subnet> mask <remote subnet> mask
   access-list 101 permit ip <local subnet> mask 10.99.99.0 255.255.255.0
   nat (inside) 0 access-list 101
                    ^^
                   This MUST be a zero

I went through the examples line for line and was able to get both working successfully, however I still have the problem where I can not have more than 1 user connected to the VPN at the same time.
