Multiple domain computers hanging on restart

Hello,

In January an update went out and when it did about half of our organization's computers now hang at restart. We tried reimaging them, but eventually they update again and the restart issue starts all over again.

We found that if we remove the network cable and cold boot the PC will come up again. We then plug the network cable in and go everything works until the next restart.

This only happens to computers on our main domain. Our security team thinks its one or two services hanging, but cannot tell us which.

What would be the best troubleshooting steps to try and find out why this is happening?

The case seems not related with WSUS. So I added the new tag and remove the old one.

I found out today that our security team put in a ticket with Microsoft Support so hopefully this gets resolved. Thanks for your help.

Sounds like problematic or incorrectly configured DNS. I'd check the domain controller and problem members have the static ip address of DC listed for DNS and no others such as router or public DNS.

How would I check that? When I look at a problem PC it just shows the two IPs I'm used to seeing.

Yes, I agree - see https://www.ajtek.ca/guides/domain-controller-dns-in-an-active-directory-environment/

If at first you don't think it's DNS - check it again!

Please run;

Dcdiag /v /c /d /e /s:%computername% >c:\dcdiag.log
repadmin /showrepl >C:\repl.txt
ipconfig /all > C:\dc1.txt
ipconfig /all > C:\dc2.txt
ipconfig /all > C:\problemworkstation.txt

then put unzipped text files up on OneDrive and share a link.

This is a lot of work, but try;

  1. Start PC, write down the exact time, wait it to hang... wait... wait... write down the time.

  2. Unplug cord, restart again and login.

  3. Open Event Viewer ang go through all System and Application node logs during the time you wrote down.

You might find the eoot cause like this. Good luck.

This I have done and there doesn't seem to be any consistent errors from computer to computer.

Though I know you have good intentions, my organization won't let me share what you asked for.

I did think of something. We use Umbrella Roaming Client and that does seem to sit as "starting" while the computer is hanging. It would match up with the DNS issues you were thinking.
