I have 2 laptops identically configured. Actually it is just one real laptop plus a virtual one obtained taking an HD image of the real one.
Both are joined to a windows domain, and I connect to the domain network via a vpn. I can start the VPN (cisco client) only after logging in, so at login time, I'm always using cached credentials.
The problem is that my password has expired. I renewed it on the real laptop (login, start vpn, change pwd, lock, unlock, done), but now the virtual one knows nothing about it. Its cached password is still the old one, so I can access the virtual laptop using my old password but then if I connect to vpn and try to access the domain I get prompted for reauthentication with my current password. I tried the "change password" dialog on the virtual laptop but it doesn't let me set the new password to my current password (as that's already my current password) and if I really change the password to something else, then I'll just move the problem to the real laptop.
How can I get the virtual laptop to realign its cached credentials with the domain controller?
