I recently installed all the Microsoft security updates
which started my VPN service to start crashing after
the connection was established.
I have (painfully) manually uninstalled the VPN
client (the normal uninstall process failed and
would not remove the client), and reinstalled it.
It did not resolve the problem. I get the windows
popup window saying "Cisco Systems VPN Client
has encountered a problem and needs to close..."
message. At that point the 'cvpnd.exe' image is
My connection is still up and running but the
only way for me to terminate the connection is to
do an "End Process" on 'vpngui.exe'. At this point
I can no longer use VPN unless I reboot my PC.
I have tried to restart the "Cisco Systems, Inc.
VPN Service" and then reuse the client but I get
another popup window saying "Secure VPN
connection terminated locally by Client.
Reason: 429: Unabel to resolve server address."
Can anyone help resolve this?
