RE: [ActiveDir] GPO not applied - thinks it is empty
Servers were handled different from workstations. Generally they were handled based on the support group which as you know varied greatly across the world. The Domain Controllers were under my purview and the way those were handled was that our supervisor set the password to some obnoxiously long and complex password and placed them in envelopes. The only time they were opened was after I asked my supervisor if the passwords were actually tested to verify they worked as expected, and then they were zipped up again and placed in the hands of some manager. Outside of that the admin accounts were checked on every DC for bad password attempts, successful logons, and password change date to try and verify that someone hadn't messed with them. I know I didn't hold the envelopes for any servers. The only admin IDs I knew passwords for were my IDs. Honestly as a domain admin, I saw no reason for me to know passwords or have any access to servers I didn't support. My job was to manage the domain, not all of the servers in the enterprise. The only time I touched any of those machines with my admin ID was when I was dragged into an issue. Generally my troubleshooting of member servers or any servers was with my normal userids or anonymous access. Computer accounts don't expire but I will take it as intended... If no one can log into a machine with a domain ID, what do you do? I have no problem using a save CD to pop the admin password. Truly and honestly, it is time tested, it works. This customer though doesn't have to do that, they have a CD that when loaded up on a specific machine, can, through some algorithm work out that machine's current password. I never looked into the process to work out how it was done, didn't need to. I always have a hacker CD with me. :o) joe -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of [EMAIL PROTECTED] Sent: Saturday, May 21, 2005 3:53 AM To: ActiveDir@mail.activedir.org Subject: RE: [ActiveDir] GPO not applied - thinks it is empty Didn't they also have the practice of writing a server's local admin password on a piece of paper, sealing it in an envelope and giving it to someone?

It seemed to have been run in the past like a series of small companies with a lot of loosely connected stuff. Sort of a federation versus a united whole. I have watched this pretty closely for a long time as I was always curious about the massive communication issues I had seen with and within MS. One extremely funny case was the fact that I used to ask the same question to like 2 or more groups all servicing the same widget company I worked for. These people were all part of MS but were obviously in very different parts of MS and were very disconnected internally, they did more bridging when in our meetings at our locations than when in theirs in my opinion. It took them a couple of years to come to the realization that I was asking the different groups the same questions and weighing the answers against each other and at times, letting them battle each other with their answers with them never knowing they were battling other MS folks. And it wasn't like these were small questions either, I don't often ask small simple questions, these were mostly deep difficult questions and the radically different opinions that came back showed the cracks. Anyway, we ran into several issues with Exchange as I have often hinted at and they were issues that they should have been hitting internally, until I found out they had such a disjoint internal configuration. Later I found out they had started collapsing the structures and pulling things back to more central locations and started hitting a lot of the same issues we had been pointing out for some time that we had been told were due to our design not due to any lacking in Exchange... It is just a guess, but I expect most everyone if not everyone has full admin of their workstations and servers. Additionally there are more forests and domains in that company than probably any where else. Many of them probably make sense like for the Windows groups working on the AD product, but I expect many of them don't make any sense, it is just people who want their own and want control over their own machines so make them and use them. I think the power and reach of ITG/OTG/GOAT or whatever it is called now is growing in the desktop space but I am not sure how much power they have over the admin ID. They almost certainly have enough deployment mechanisms through AV software and SMS on the corporate standard workstation load that they have multiple paths into boxes through localsystem so knowing the admin ID at any given moment probably isn't all that important. Well it isn't that important anyway as we all know, if you want into a box, you get it in front of you and insert a cd and you are on. If MS is going to work on issues with IDs at all, I would ask that the focus be put on Service IDs and how services work in general or mechanisms to help easily change passwords of service IDs. So many companies run around with non-expiring service IDs not realizing how insanely insecure that is. Heck, MS themselves was hacked because of unchanged service IDs several years back and I recall hearing how billg had put out a message that they were going to stop using non-expiring accounts. I expect that dropped by the wayside because we haven't seen many new ways of handling services (though I do say thanks for localservice and networkservice). Think about all of this logically You force password changes so that a password can not be the same thing for long enough to hack it through various brute force methods or because it has been the same too long and you don't know who all has the password now. So then you take IDs that are more likely targets for hacking than normal IDs due to usually having more power/rights and being known by multiple people so there is always question as to who did what and then you make them non-expiring and let them stay unchanged for a year or more. What brain dead security people are making those decisions? They just made a mockery of all their other decision making processes for setting a password change policy in the first place. If anything, service IDs should be changed more frequently than normal user IDs. The number one argument I hear about having non-expiring IDs is that the password needs to be changed in a controlled fashion, it can't just be allowed to expire... My response to that is always... Fine, change it in a controlled

RE: [ActiveDir] GPO not applied - thinks it is empty
number of hands far exceeds the second number. Who wants to take responsibility for knocking down a running application? This is the kind of thing I get fired for because I will take that responsibility, I think it is more important that they be secure because I know the minute they are compromised they are going to chew me out asking who did it and how. I have seriously had managers ask me who logged onto a specific ID. My response... Well whomever has the password of course! No, specifically who logged on and did this. My response... I don't know, the mechanism I have for tracking the WHO is completely compromised by how you use the system with that ID. For a small fee, we can install a web cam on every machine in the world that people can log into and we can work out a mechanism around that if you would like to track it the next time your application gets hacked. Anyway... :o) I would like MS to put out guidance on making services with self setting passwords as well as any services they have that require userids doing the same. If people write services they can do that now but many don't because they think... Well crap I have to store the plain text password somewhere... If the ID is a domain ID, don't do it that way, give the service ID the ability to SET its own password. Then it can randomly generate a password once a day, once a week, once a month and set it. Now the issue, from what I understand, is that the service has to be restarted... I would like to see a mechanism that makes this so it isn't required. I expect it is possible, users do it now when they change their password interactively. While it is a troubleshooting good idea to log off and log on, it isn't always required. It should never be required. Changing local machine IDs is much harder if the ID isn't an admin itself on the machine in question. Those currently would have to remember the old password. But the question is... If you have a local ID for a service... Why does it have to have a password at all? Why can't it be a service only password that you get to specifically set the rights for (i.e. not use localservice which applies to all services running as localservice). I would like to see a similar domain ID as well so people don't have to be stuck with networkservice or a regular ID that needs changing. That one is a little tougher to overcome though. joe -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of [EMAIL PROTECTED] Sent: Thursday, May 05, 2005 9:30 AM To: ActiveDir@mail.activedir.org Subject: RE: [ActiveDir] GPO not applied - thinks it is empty I used to store the password in the batch file before I got my brains bashed out on this list.

Run gpotool.exe (from Win2K reskit or part of XP and 2003) against your DCs and see if any of them show a revision number of 0 for the computer side of the GPO containing your script. This could still mean that you have some issues with sysvol replication. Essentially, there is a file called gpt.ini that is stored with the GPO in sysvol on each DC. This file contains a version number that lists how many changes were made to the computer and user sides of a GPO. That version should be the same as the version of that GPO held on the versionNumber attribute of the GPC object in AD. If there are discrepancies, then gpotool will tell you.

These computers are part of a group, I have applied the policy to this group, and set the security permissions appropriately. When I run gpupdate on the pc, I get no error in the Event log, but when I restart the machine, the administrator account password has not been changed. I have run replmon.exe and have found that 1 dc (out of 30) is not replicating, as it is out of hard drive space on c:. Could 1 out of 30 dc's be causing the problem, or is there something else I am missing? How long should it take, before the policy takes effect? Thanks, Brenda
RE: [ActiveDir] GPO not applied - thinks it is empty
Add to the methods 1. Put machine on hub and sniff traffic and watch script come down. 2. Put a password filter in place and have it alert you that the password was changed. et alii From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Eric FleischmanSent: Wednesday, May 04, 2005 3:10 PMTo: ActiveDir@mail.activedir.orgSubject: RE: [ActiveDir] GPO not applied - thinks it is empty If I could ask what might be the obvious, from a security perspective. If you have a policy out there resetting the local admin password, how are you storing the new password in the script? Hopefully you have something very clever in place, else I can get the local admin password out of your policy in so many ways: If you didnt consider this at all, I bet the policy is ACLd with AU having read, so I can just read it out with notepad. If you were clever enough to acl the policy so that only the machine accounts can read it, I could own a machine (perhaps I already do.perhaps I am in the local admins group on one of the boxes, because it is _my machine_) and just open the policy while impersonating the machine. Or get the machine to do it for me (since I own it, I can make it do my bidding). etc And if you havent taking precautions, you should assume local admin on any machine with this password is local admin on them all. For it only takes one bad apple to spoil the whole bushel. ~Eric From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Brenda CaseySent: Wednesday, May 04, 2005 11:11 AMTo: ActiveDir@mail.activedir.orgSubject: RE: [ActiveDir] GPO not applied - thinks it is empty Thanks Darren- I ran the gpotool as you suggested.
