Windows 10 - 1809 update Active Directory error/can’t log in!

Hey,

So I have about 10 computers attached to a local NAS (Synology) as an Active Directory server. Let me point out that each of these computers has an ethernet connection to the server, is running an activated version of Win 10 Pro and has roaming profiles e.d. This all worked fine until today.
Today collegues of mine started to get the Windows 10 v 1809 update. Nothing to worry about, really, was my thought. But as the update finished, logging in 'stalled'  the computer. There is a video of the situation after logging in here: https://www.reddit.com/r/Windows10/comments/9l2hlt/windows_10_1809_update_active_directory_errorcant/
It is important to know that the 'older versions'  of Windows 10 don't have any problem logging in!

So what did I do to troubleshoot?
 - Rolled back the computers that could be rolled back. Fixed the problem for them.
 - Created a clean windows installation with v 1809. I can add the computer to the Active Directory although when I reboot and try to login to a user, the same problem occurs.
 - Tried removing all GPO's. No effect.
 - Tried different (new) users. No effect.
 - Tried changing network settings. No effect.

What I probably should add is that the used DNS server for windows is 192.168.0.100, which is the NAS which runs the DNS server and Active Directory.
I am really confused. Can maybe someone help me out to solve this problem?
And if not, maybe someone knows more technical details on what changed in this new version that might lead to my problem?

Thanks a lot!

Hi IT. I'm Greg, an installation specialist and 9 year Windows MVP, here to help you.

I would ask this at our sister forums for IT professionals Technet, as this is strictly a consumer site: https://social.technet.microsoft.com/Forums/en-...

I will add that I would always troubleshoot with only a single monitor, and to check your Display driver is fully updated and working properly.

I hope this helps. Feel free to ask back any questions and let us know how it goes. I will keep working with you until it's resolved.

Hey Greg!

Thanks a lot for your reply to my previous post. I followed your tip on troubleshooting with one monitor. Thanks for this tip, it got me further in the process! I have the following update after another day of troubleshooting. Hope someone can help out!

First I tried logging in via Safe mode. The system almost instantly crashed giving me the following error:

sihost.exe 

System Warning Unknown hard error 
<ok>

So that didn't help. Next I logged in reguarly and the screen started flashing again. I waited for an hour to see if anything happened but unfortunately not.

We got to this situation:
 - Local login works (seems fine)
 - AD login crashes
 - Ctrl + Alt + Del works. So I can logout crashed user
 - Loggin in locally again makes the "hi, welcome'  video appear. After this it seems the local user has partly reset.
 - Everything is up to date (double checked). 

What I did next was disconnecting my screens. Suprisingly this helped with the flickering, and so I could log in to my AD profiles, although still there seems to be a problem with the server connection. 
It seemed I had this problem (Edge doesn't have internet connection) https://techcommunity.microsoft.com/t5/Windows-10/Windows-10-1809-Edge-not-loading-pages/td-p/266050 which I could fix by enabeling IPv6 (It is weird this is obligated right? Or is this a driver issue?)
Then it seemed I also had this problem (search bar not working) https://basics.net/2016/12/20/windows-10-cant-type-in-search-field/ which I haven't really been able to fix by following the numerous online tutorials on how to fix this.

Also the following errors occur in the error log:

The User Profile Service service terminated unexpectedly.  It has done this 1 time(s).  The following corrective action will be taken in 120000 milliseconds: Restart the service.

So not sure what to do now. Seems everything is very unstable.

Any thoughts?

This would be the type of advanced IT Admin information that they could process better at Technet which is the MS forums for System Administrators: https://social.technet.microsoft.com/Forums/en-...

As I had written earlier these are only consumer forums for individual consumer problems.

I think this is it for now:

Anyway, rolled back all devices except one. Still experiencing the problems, so I'll just wait for a new update first before seeking technical help. 

Thanks for the replies!

We have experienced the same issue in some computers and finally we discovered that by removing the HOMESHARE value in the AD account settings, the users were able to logon. Maybe it might help you.

We've experienced the same issue.  This was only experienced by users that, under the Profile tab in their AD account, had a UNC path in the Local path that was not mapped to a drive letter.  Users with a drive letter assigned were fine. Once we changed Local Path to Connect to drive letter users were able to log in successfully.

Here's a quick script I used to find and change the settings.  Probably not the most efficient, but it was quick and worked.

To get the list: 

Get-ADUser {-filter enabled -eq $true} -properties SamAccountName, HomeDirectory, HomeDrive | where {$_.HomeDirectory -like '*\users\*' -and $_.HomeDrive -ne 'D:'} | FT SamAccountName, HomeDirectory, HomeDrive

To make the change:

Get-ADUser {-filter enabled -eq $true} -properties SamAccountName, HomeDirectory, HomeDrive | where {$_.HomeDirectory -like '*\users\*' -and $_.HomeDrive -ne 'D:'} | Set-ADUser -HomeDrive 'D:'

Also, FYI -while looking at Task Manager while the screen flashing was going on we saw the Explorer.exe process starting, hanging, starting, hanging, starting, hanging, etc.

Thankyou!!!!  I have been fighting this for about 3 months on about 6 different computers all using Active Directory from a Synology server.  The symptoms varied slightly but most of them end up with a flashing task bar and or an SIHost error.

Based on your suggestion I checked the Active Directory service on the Synology and each user had a home path set in their profile set to "\\10.1.10.151\home" changing this to use a home path with a drive letter solved the problem.
