[Openvpn-users] 2.1_rc4 Client not working in Vista

Good day.  We’ve been battling with our OpenVPN client in Vista for a few weeks now.  We are getting TLS handshake errors trying to connect with the 2.1_rc4 client.  From the remote site, we can make a connection using Windows XP and Mac OS X (using Tunnelblick) without incident.  When we try to connect from the same location with Vista, we receive the error “TLS Error: TLS handshake failed”.  This does not seem to be a firewall issue, as suggested by the OpenVPN FAQ.  In Vista, we “Run as Administrator” the client, Windows Firewall is disabled, and no third-party internet security software is installed.  Logs with verbosity 6 are pasted below; endpoints have been masked.  We recently updated our server to the latest version of OpenVPN; it did not help.
