Cisco VPN Client Connectivity on Vista Ultimate

[Guest]

I am getting 418 Error when I try to connec to my corporate office desktop
using Cisco VPN client (I have the 5.0.x version of VPN client that supports
Vista). Is any one experience such error? and were you able to Solve it?

Same here, no success.

Tried disabling Vista's TCP packet size scaling feature
netsh interface tcp set global autotuninglevel=disabled
changing the client between TCP and UDP transports, disabling
ArpRetryCount (one line)
reg add HKLM\System\CurrentControlSet\Services\Tcpip\Parameters
/v ArpRetryCount /t REG_DWORD /d 0 /f
disabling firewall - nada.

We're going to ditch the PIX and replace it with a Snapgear SG720.
