Step 4 The user returns and enters the Entrust password, then clicks Yes to the security
hash check question.
Step 5 The VPN connection completes, and data can be passed. The VPN dialer appears
as not connected.
Step 6 Clicking Connect returns “A connection already exists”. The user clicks Cancel,
and the dialer appears connected in the system tray.
The VPN connection can be used as a normal connection.

This issue occurs on a Windows NT PC that is running ZoneAlarm or Sygate
Personal Firewall, if the VPN Client is set to Start Before Logon and an
upgrade to the VPN Client is implemented. Do not attempt a connection
before the logon when you reboot, because both firewalls do not
automatically give the VPN Client permission to access the Internet. Both
firewalls see the upgrade as a new application attempting to access the
Internet, and it requires user permission through its pop-up menus. The user
must logon to the Windows NT PC using cached credentials, then launch a
VPN connection. The firewall then asks permission to allow the VPN Client
to connect. Answer yes to each connection. After that, Start Before Logon
works fine.

The message, “The necessary VPN sub-system is not available. You will not
be able to make a connection to the remote IPSec server.” might appear on a
PC when Start Before Logon is enabled on the Client and ZoneAlarm is also
running. The message appears when the ctrl+alt+del key combination is
pressed. This has happened because the Cisco Systems VPN Service has
terminated unexpectedly.
Workaround:
Logon to the PC with cached credentials, open “Services” in control panel
and start the VPN service. A connection to the VPN Concentrator will be
possible once the service has started.
