Copy cached Xp password from one PC to another

Hi folks

I have two Windows Xp machines. My account on both machines used to have identical passwords, connected to a domain. I access the network via VPN.

I changed the password on one of the machines (and this change has obviously rolled through Active Directory). Now the other can't connect correctly to the domain. I can still log in to the machine, but when I VPN in it appears to connect but I get messages to lock and unlock the computer. I've done this several times but no luck.

How do I copy the cached password from the one to the other?

You can't copy cached passwords.  You may be able to copy the security reg hive from one machine to the other but you would still need to access the registry on the machine you are locked out of.  Try downloading one of the many XP password reset disks out there so you can get into the locked machine.  Then log onto the vpn with your new password.

No... It is hashed.  You just cannot copy cached passwords...  To sync your password, you have to physically connect to the domain BEFORE you log in.  Set your VPN to authenticate before your AD does, if you can do that, or take your machine to a place where you can physically connect.

You can try exporting HKLM\Security\Cache from one laptop to another.  You will need to run regedit under the account SYSTEM since the SYSTEM account is the owner of this key.  You can do this by using psexec from the Sysinternals PSTOOLS suite:
psexec -s -i regedit.exe
But I wouldn't recommend it...Microsoft goes out of their way to lock you out of this specific registry branch.  You can't just log in as an Administrator and open the key...you have to impersonate yourself as SYSTEM.

You can log into the vpn before logon by selecting "logon using dial up networking"  Log into the vpn with your correct password and it will auth you into the domain. Or bring the machine into the office and log in there.  I have copied security hives in old versions of windows (98, original XP and 2000 server with some success but have also hosed a machine or two along the way.  Best bet is the vpn or physically bringing the box into the office.

I have no objections to that resolution.
