Have a vista business on dell latitude xt. Was trying Cisco VPN Client
(5.0.03.0530) and having problem connect thorough ZTE wireless modem
(vista hung).
Then i installed SP1 and KB952876 patch provided bu Cisco and
reinstalled Cisco VPN Client (5.0.03.0560), and have error 442 on
every connection.
Then i was trying to manually uninstall Deterministic Network Enhancer
and ended up not able to install cisco vpn anymore - something like
network configuration lock is is held bu another application.
I think better solution is to reinstall to WinXP tablet...
