Directory Services Restore Mode

Running Veeam Backup and Replication, a Microsoft Windows Server Domain Controller may boot in to safe mode and directory services restore mode.

About a week ago, I loaded up Veeam Backup and Replication in to my test environment. It’s a fantastic product, and it’s working great, however today I had a little bit of an issue with a DC running Windows Server 2016 Server Core.

I woke up to a notification that the backup failed due to a VSS snapshot issue. Now I know that VSS can be a little picky at times, so I decided to restart the guest VM. Upon restarting, she came back up, was pingable, and appeared to be running fine, however the backup kept failing with new errors, the event log was looking very strange on the server, and numerous services that were set to automatic were not starting up.

This specific server was installed using Server Core mode, so it has no GUI and is administered via command prompt over RDP, or via remote management utilities. Once RDP’ing in to the server, I noticed the “Safe Mode” branding on each corner of the display, this was very odd. I restarted the server again, this time manually trying to start Active Directory Services manually via services.msc.

This presented:

Event ID: 16652
Source: Directory-Services-SAM
General Description: The domain controller is booting to directory services restore mode.

Screenshot:

Directory Services Restore Mode

The domain controller is booting to directory services restore mode.

 

This surprised me (and scared me for that matter). I immediately started searching the internet to find out what would have caused this…

To my relief, I read numerous sites that advise that when an active backup is running on a guest VM which is a domain controller, Veeam activates directory services restore mode temporarily, so in the event of a restore, it will boot to this mode automatically. In my case, the switch was not changed back during the backup failure.

Running the following command in a command prompt, verifies that the safeboot switch is set to dsrepair enabled:

bcdedit /v

To disable directory services restore mode, type the following in a command prompt:

bcdedit /deletevalue safeboot

Restart the server and the issue should be resolved!

Upgrading to VMware vSphere 6.7? Remember that vSphere vDP is no longer supported!

Ready to jump the gun and upgrade to vSphere 6.7? Hold on a moment…

You’ll remember some time ago VMware announced they are dropping support for vSphere vDP (vSphere Data Protection). If you’re running this in your environment, it will break when upgrading to vSphere 6.7.

A better idea would be to migrate over to a product like Veeam, however please note that as of this date, Veeam does not officially support vSphere 6.7. Support should be coming in the next major update.

10ZiG 5948q Zero Client

In an effort to truly showcase the capabilities of VMware Horizon View and the 10ZiG 5948q Zero Client, I wanted to put together a demo showing the ability to run Red Hat Enterprise Linux (RHEL 7.4) in a VDI environment.

First and foremost, this was super easy to setup. It was almost too easy…

Sidenote: Remember, my company Digitally Accurate Inc. is a 10ZiG partner. We can configure and sell 10ZiG Zero Clients (and thin clients), help with solution design and deployment, and provide consulting services! Contact us today for information or a quote! We sell and ship to Canada and the USA!

Please see below for video:

You’ll notice during login that after the credential prompt multiple desktops were available (we chose to log on to the RHEL instance) to choose from. You’ll see further on in the video versioning and specifications as well as video playback. Again, please note that my environment does not have any GPU or 3D rendering.

Please Note: The momentary black border on the bottom right side during login, was due to a resolution change on the VDI session. This was the first time logging in with this client, and the border doesn’t normally occur unless changing resolutions.

Equipment/Software used in this demo:

10ZiG 5948q Zero Client

As promised in my previous post which covered my first impressions, here are some pictures and video of the 10ZiG 5948q zero client in action! In the videos I demonstrate video playback as well as the USB redirection capabilities of the 10ZiG Zero Client and VMware Horizon View. Scroll down to the bottom for videos!

In this video, I demonstrate the capability of the 10ZiG 5948q zero client connected to a VMware Horizon View server (via a Unified Access Gateway) playing a video from YouTube. Please note that the ESXi server does not have a GPU and 3D rendering is disabled for the test (this is as low performance as it gets).

In this video, I demonstrate the capability of the 10ZiG 5948q zero client using USB redirection on a live VDI session.

And finally, here’s a video of a 10ZiG zero client cold boot for those that are interested.
