#104861 - 2003-09-19 04:25 PM Changing Cached Domain Account Password
MaestroG MaestroG Fresh Scripter Registered: 2002-12-30 Posts: 28 Loc: Tulsa, OK	I am using the ADSI ChangePassword method of changing the domain password with KixTart. My problem is with our VPN connected users who disconnect their VPN session before logging off. They end up having to logon to their (disconnected) PC with their old domain password and connect to VPN (the domain) with their new one. This is confusing and causes resource and access problems in the long run. Apparently, the ADSI method works and changes their password, but does not update the associated cached account password on the local system. The only thing I know of that will change both is running CTRL-ALT-DEL and clicking the Change Password button. If the VPN user is connected and then do it this way, it changes both, but we want to call it and control it in a script. Does anyone know how to update the cached domain account password so I can change it when I do the ADSI domain password change? Many thanks for your help. G

Instead of having your VPN users logon with cached creds, you should have then logon through VPN at bootup. _________________________ Give a man a fish and he will be back for more.

You'd think I'd get tired of the whiplash I always get and learn. The VPN client does not integrate with the MSGina. They have to logon first and run the VPN Client.

You could always stick to just lowercase kixtart... a much lesser sin. _________________________ Give a man a fish and he will be back for more. Slap him with a fish and he will go away forever.

Les Les KiX Master Registered: 2001-06-11 Posts: 12734 Loc: fortfrances.on.ca	Sorry, I'm stumped, but then again, I'm not one of those scripting geniuses. One thing I learned is that if you build "brain-dead simple solutions, you create brain-dead users. I say let them learn how to use the tools as they are. They will be the better for it. _________________________ Give a man a fish and he will be back for more. Slap him with a fish and he will go away forever.

It's our HelpDesk group that is the squeeking wheel here saying that too many calls will be produced to handle if it is not fully automated. Hey, I've just about done everything I can. I think it's gonna come to that after all.

Shawn Shawn Administrator Registered: 1999-08-13 Posts: 8611	I've been scouring MSDN looking for any API's related to changing cached credentials, nothing found so think what your trying to will be tough, even searching the web in general isn;t yielding much. What I would try, if it make sense to you, is change the domain password with ADSI, then maybe reset the secure channel from workstation to domain using NLTEST from RESKIT with /SC_RESET:<domain> switch.

Shawn Shawn Administrator Registered: 1999-08-13 Posts: 8611	or, the other thing you might try, stop and restart netlogon with shelled nets: net stop netlogon net start netlogon Don't be afraid to try this, we do it all the time and it fixes a multitude of sins.

MaestroG MaestroG Fresh Scripter Registered: 2002-12-30 Posts: 28 Loc: Tulsa, OK	Shawn, Tried both with no luck. I think I may open a case with Microsoft. There has got to be a way to kick off that golden code that sync's the cached password with the domain password. It does it at logoff (if you are still connected). It also does it when you do a Change Password from CTRL-ALT-DEL. Thanks everyone. I'll let you know if I find an answer outside of this site. In the meantime, keep the ideas coming.

Shawn Shawn Administrator Registered: 1999-08-13 Posts: 8611	stand by ... want you to try something ... Bryce and I whipped up this little c-program that actually calls the win32 api for changing the password, before you call MS, might want to give it a try: http://www.isorg.net/kix_tools/ look for changepass.zip, in there a sml util called: CPWD.EXE that works like this: shell '%comspec% /c cpwd @domain @userid $oldpass $newPass > nul' Worth a shot, might force the cache to reset but not overly hopefull. -Shawn [ 19.

MaestroG MaestroG Fresh Scripter Registered: 2002-12-30 Posts: 28 Loc: Tulsa, OK	Right now, it keeps telling me wrong current password. I'm trying to figure out why right now since I have verified my current password. I'll keep trying unless you know something I don't and I'll post again later if I get it working or not. G

Shawn Shawn Administrator Registered: 1999-08-13 Posts: 8611	Ok, let me give a try here, what OS ? Think this one might work if we can get it going, this API is the one that allows the user to change their own password, should be the same one used by the ALT-CTL-DEL thingy ...

Chris S. Chris S. MM club member Registered: 2002-03-18 Posts: 2368 Loc: Earth	My guess is that G is not on AD. Also, the reason it works for Shawn is that he is now on AD. The issue at hand is that kerberos is used to change the computer account password. NTLM can be used, but requires that the user fire off the API by performing a change password by doing crtl-alt-del and choosing Change Password while connected via VPN. We had this same issue with our VPN users until we made the switch to AD. [ 19. September 2003, 22:35: Message edited by: Chris S. ]

Shawn Shawn Administrator Registered: 1999-08-13 Posts: 8611	well tbh, this program was tested many moons ago when I was still on NT4, plus the tests I just performed today where from home, against local accounts on the workstation, no AD ... so not really sure whats up wid dat ...

Shawn Shawn Administrator Registered: 1999-08-13 Posts: 8611	sorry, me and chris are talking about this thread offline on MSM ... question: are you running this over VPN ? if yes, could you try running it outside of VPN just to see if it works there. -Shawn

Ultimately, switching to AD has fixed it. Alternativly, you could go with Microsoft VPN. You won't get much help from Microsoft, I'm afraid.

MaestroG MaestroG Fresh Scripter Registered: 2002-12-30 Posts: 28 Loc: Tulsa, OK	Actually, I'm just trying it on my XP and 2K workstations in the LAN first to see if the change password works before I try it with a laptop over VPN. I can pretty much duplicate the behavior also by changing the password and then pulling the NIC cable and then logging off. If I can't log back on with the new password, I know the cache wasn't updated. This is essentially what is happenening in our scenario when you break it down anyway. I'm not sure why this API tool wouldn't work. Are their any dependencies or some other preparation I should know about or do? G
