This is just a helper post to prevent people wasting a morning like I just did!
Our team connects to our domain controller, source control server, build server etc via a VPN. I am doing Sharepoint development at the moment using Microsoft Virtual PC, and I've set up the same VPN connection inside the Virtual PC (running Windows Server 2003) so it can see the network as well.
Recently my domain password expired, so I changed it from my main workstation. However when I tried to use my new password on the Virtual PC to connect to the domain, it refused me - I had to continue using my old password to log into the box. Presumably it had cached my old password for connecting to the domain.
Once I logged in however, I was able to open network drives, open remote desktop connections etc by entering the new password. Windows knew I had changed my password and was coming up with the message telling me to lock the computer (CTL-ALT-DEL) then unlock it using my new password. But when I did that, it wouldn't accept my new password.
I tried logging into Windows using a Dial-up connection (the VPN) - when I did that, the VPN connection accepted my new password, but once it connected to the VPN, Windows still wouldn't accept my new password. So the only way I could log into Windows was to disconnect the VPN and use my old password.
After much googling and trying various things, the only way I could resolve the issue was to change my password again - this time, from inside the Virtual PC, by CTL-ALT-DEL'ing and selecting the "Change Password" option. Once I did that, I locked/unlocked my workstation and used the new password. I logged off the Virtual PC and logged on again (with Dial-up connection unticked)... and PRESTO! Back in business.
Hope that helps someone!
