Most laptops can connect to our VPN, but my personal Dell laptop cannot due to the following error that occurs almost immediately after clicking Connect button on the Cisco VPN Client - Version 5.0.02.0090:
Secure VPN Connection terminated locally by the Client.
Reason 429: Unable to resolve server address.
Some folks said to un-check Properties>Transport>Enable Transparent Tunneling but it seemed to have no effect.
The laptop can connect to the internet and all protocols work: HTTP, EMail, FTP, etc.
