I have one Vista laptop that refuses to connect to a PPTP VPN connection.  An exact same model laptop with Vista on it connects just fine and a separate desktop from home can connect as well so I know it is not a setting on the Cisco VPN 3008 concentrator.  Using the built-in Windows VPN client with all default settings.  Firewall has been turned off to try to get this connection up and running and still no go so I don't think it is blocked ports or protocols.  

If I attempt to connect with default options, it just waits at the "Connecting to" screen and never acts like it connects even though to try to authenticate my username and password.  I have these entries in the event log:

CoID={A28CFFD9-68D6-4AD4-B813-816E40F86F56}: The user Domain\User has started dialing a VPN connection using a per-user connection profile named VPN Connection. The connection settings are:
Dial-in User = User
VpnStrategy = PPTP then L2TP
DataEncryption = Require
PrerequisiteEntry =
CompartmentsEnabled = No
AutoLogon = No
UseRasCredentials = Yes
CustomAuthKey =
AuthRestriction Mask = 0x00000200
RasIpv4DefaultGateway = Yes
Ipv4AddressAssignment = By Server
Ipv4DNSServerAssignment = By Server
RasIpv6DefaultGateway = Yes
Ipv6DNSServerAssignment = By Server
IpDnsFlags =
IpNBTEnabled = Yes
UseFlags = Private Connection
IpSecFlags = No Pre-shared key
ConnectOnWinlogon = No.

CoID={A28CFFD9-68D6-4AD4-B813-816E40F86F56}: The user Domain\User is trying to establish a link to the Remote Access Server for the connection named VPN Connection using the following device:
Server address/Phone Number =
Device = WAN Miniport (L2TP)
Port = VPN0-1
MediaType = VPN.

CoID={A28CFFD9-68D6-4AD4-B813-816E40F86F56}: The user Domain\User dialed a connection named VPN Connection which has failed. The error code returned on failure is 800.

I have attempted changing the options in the VPN from "Type of VPN" Automatic, to PPTP only and then the error code changes to 609 which means "The device type does not exist."  The other two Vista machines do not need this setting changed.  

I have tried using my LAN and Wi-Fi connection and both fail.  I need some help troubleshooting this.  I hate to reload Vista just for this problem but I need to be able to work remotely or the laptop has no advantage.
