Hi,
I am at Starbucks trying to VPN into a client VPN but it just starts to connect then nothing, except says at bottom "Not Connected"

The Log shows:

Cisco Systems VPN Client Version 4.8.00.0440
Copyright (C) 1998-2005 Cisco Systems, Inc. All Rights Reserved.
Client Type(s): Windows, WinNT
Running on: 5.1.2600 Service Pack 3
Config file directory: C:\Program Files\Cisco Systems\VPN Client

1      16:25:51.180  05/20/13  Sev=Warning/3      GUI/0xA3B0000B
Reloaded the Certificates in all Certificate Stores successfully.

I wanted to know what I should not count on while travelling.

If you can ping the IP/URL of your vpn server (ASA, PIX, etc.) or at least get out to websites but you get no response from the vpn client, there are usually two reasons. There is a major configuration issue and you could get the network admin on the phone, or the guest network you are on blocks vpn connections (and there are a lot of free wifi places that do in fact block vpn connections). If you are being blocked, you would need to talk the network admin into enabling Anyconnect which run over SSL the same as secure websites. This may be more difficult to accomplish as it usually comes with a licensing cost.

To figure out if you're being blocked, you would need to get your network admin on the phone to see if he/she can see the connection attempt coming in or not. If they can't see the attempt, you are likely being blocked.

Thank you... I didn't try pinging which I should have :-)
But - it does see the server, gets replies back but not VPN connect.

I did clear the log and try again and it doesn't even give that warning.. that must have been an old warning. :-)

So I would need a usb network card supplied by my work to get around blocking VPN.. yes?

So there is a setting on the wireless that is set to block or allow VPN?
So even at home if it is not set to allow VPN I'm out of luck?

When I said that the vpn would be blocked, I mean the company providing the wireless is blocking VPN traffic. So it would be Starbucks, or Panera, or La Quinta Inn, or whomever that has equipment in place to block your VPN connection. I would doubt that a setting on your computer is specifically blocking VPN traffic.
The SSL VPN I mentioned is VPN all the same except that it encrypts in the same way that a banking website would encrypt traffic so places that block VPN traffic have no way to detect that you're using an SSL VPN because it doesn't appear any different than regular (secure) web traffic.

At home I wouldn't suspect anything to block you from connecting to VPN except configuration issues. Things like not actually being online, not having the correct VPN profile, invalid credentials, etc. There's always the chance that this is a firewall issue at your place of business which would be most likely affecting many users. This may be a job for your network admin again whether firewall or PC related.
