Computers Join Domain before Hostname Changes

[george1421]

@Quazz said in Computers Join Domain before Hostname Changes:

As far as I know <ComputerName> doesn’t work in unattend on Windows 10 anwyay.

It works the same in win10 as in Win7. In my setup I don’t have the FOG client connect the computer to the domain or set the system name. I do that with a postinstall script because I need to control where the device connects in AD depending on the target location and image being deployed. Because of the dynamic nature of this OU placement it was just easier to calculate the values, update the unattend.xml file and let Windows OOBE setup do the rest.

@Wayne-Workman The problem has been happening to all machines indiscriminately. Each image is made on that respective model of computer, so the only thing different would be drivers installed on each image. We use the same unattend file for each image.

[Wayne Workman]

@zpoling can you disable domain joining on a computer and image it? And then observe it’s renaming? Provide the log for that too? This is to eliminate variables and try to isolate what’s happening.

[george1421]

For clarity, will you confirm that you DO NOT have the following section in your unattend.xml file? The reason why I ask is that I could see a potential for a race condition between the unattend.xml connecting the device to the domain and then the fog client doing its bit since the fog client does have a check in interval that also impacts timing of when things happen.

@Wayne-Workman The error stated in the OP doesn’t occur if I tell the machine to join the domain after the fog service is done with post-image tasks.

@george1421 That string is not in our unattend file.

[george1421]

@zpoling ok as a final test (just to say absolutely the fog client is suspect here).

Can you either disable the fog service when you deploy to this computer so that it never runs on the target even for 1 second? In my case when I install the fog client on the reference image I stop and disable the service immediately, then proceed with the MDT install of the other applications.

Then when the target system completes the installation process just before the login screen comes up I run the commands in the setupcompleted.cmd to set the service to auto start and then start the service. At that time then the fog client does what ever it has to do. If you enable the fog client the same way, then just disable the code that changes the fog client startup from disabled to auto. This way the fog client never runs.

So then the things to check for becomes this:

1. The client should never ever connect to AD
2. The name of the machine will be what ever windows selects as the default computer name. And this will not change.

Make sure these settings are consistent for 30 minutes. Then set the fog service to auto start and then start the service. Observe and report what happens. Understand I’m not doubting that this is happening, I’m trying to isolate the fog service running from the OOBE setup doing something unexpected.

[zpoling]

@george1421 That’s how I have our fog service set up as well; Setupcomplete.cmd sets it back to auto. I’m assuming you want me to disable the early hostname changer too since you said the name of the machine should be the Windows default.

To note before I start this; if the client isn’t told to join the domain, it wont, even if the fog service is running.

I’ll get back to you with the results!

[Wayne Workman]

@zpoling I would leave early host name change turned on, and disable the code that re-enables the fog service just as George described. This test is to determine what’s going on with the hostname.

[george1421]

@Wayne-Workman I would suggest to turn off everything that could change the machine. We need to establish a normal baseline. I know it is a bit of a pain to go this route. But the first step is to turn everything off, then one thing on at a time. The next step after getting a baseline is to turn on the early name changer and see what that does.

I have to revert to the old adage of: You have to find out where the problem isn’t to be able to find out where it really is.

[zpoling]

I’m starting the image process as I am typing this.

The fog service has been disabled in this image and the setupcomplete.cmd has been removed, so the service should not start again. The early hostname changer has been disabled as well.

Imaging is complete. The unattended setup is occurring now.

Just logged on for the first time. It has a default hostname and the fog service is not running.

After 30 minutes, nothing has changed. Nothing has called for the computer to restart.

After a manual restart, the same has been observed. The hostname is still default and the service is not running. I am going to start the service and see what happens. It should try to change the hostname and join the domain, as both settings are there. I will check the default computers OU and see what appears after the first reboot.

After the manual reboot, the computer made it to the log on screen but soon rebooted. The default computer name never showed up into the default OU, but the specified name on fog did. This means that the original issue did not occur.

Does this look normal? If any of you would like me to test another factor, just let me know what to do and I’ll get it done.

On another note, I imaged 20 computers this morning while I was watching this test machine was working. I told them not to join the domain until after they were all correctly named and they all joined the domain correctly. The issue only happens when the machine has not been renamed already.

Why such an old version of FOG?

[zpoling]

@Tom-Elliott We never update fog unless we have major issues with it. Windows 10 was actually what made us get away from .32. Should I try updating it?

[Quazz]

@zpoling Basic rule of thumb for the trunk version is if you’re running into issues, updating might resolve it.

[zpoling]

@Quazz Ah. I was taught on the principle of “if it’s working, don’t fix it.” So even if it’s a small issue such as this, updating is the goto option? Fog’s updating as I type. I’ll try that from now on. I’ll report back if the issue keeps happening.

Thanks for all of your help, everyone!

[Quazz]

@zpoling I probably update it 3 times a day or more, but then again I’m in the testers group for a reason.

[george1421]

Just be aware that the update process is a little aggressive on the development trunk (or sometimes just called trunk). Once 1.3.0 is finally released then the need to update every so often will stop (until they are ready to release fog 2.0, which I would expect to have a pretty long trunk release too).

[zpoling]

After updating Fog, the issue is still occurring.

[zpoling]

@Quazz After updating Fog, should I reboot the server?

[Wayne Workman]

@zpoling so at this point, after those tests, we can safely say the actions of the fog client are causing the issue.

However I still don’t understand why… there’s a thread around here where joe lists the order in which the client does things. I’ll try to find it.
