You don't want to install LTSC branches on desktops, the official word is that Windows 10 LTSC is for, like, aircraft control computers. I think there are some technical limitations why certain apps won't work on LTSC, but also I think it's a ploy by Microsoft (that I happen to agree with) to make LTSC as painful to use as possible, otherwise every enterprise would just install LTSC and do big fleet-wide upgrades every 5 years like they did with XP/Vista/7/8/ etc instead of sticking with the rolling releases.

I manage ~1500 LTSC systems. Instrument control machines, mass spectrometers, MRIs, plate reader robots, liquid chromatographs (we've got someone who figured out how to do 2D liquid chromatography). And that number is going up as the Win7 systems get migrated.

Counterpoint: LTSC on desktops is fine and good, and there are no hidden catches or gotchas. The only real stumbling block is that as a release gets old, it’s CPU support will lag behind releases and it will flip out on newer kit.

Seeing LTSC means someone somewhere has chosen to use Windows wrongly. Sometimes in cases like mllaneza mentions it's the hardware vendor and you're stuck with it, but using it should be considered a last resort.

If your use case can not tolerate automatic updates, it shouldn't be running Windows 10 desktop edition and probably shouldn't be running Windows at all.

Seriously, unless a vendor is specifically telling you "You must use LTSC because ..." then you should almost universally reject using it.

Yes, it works.

Just off the top of my head, you're not going to get access to the Windows Store and you're going to make Azure AD Hybrid Join a lot more of a pain in the rear end.

I'd argue that there's no good reason to use it outside of the already discussed very specialized use cases.

About once a year, someone yeets into a call with the Windows client team and says, "Hey, have you thought about LTSC?"

As I understand it, non LTSC versions of Office will Soon :tm: no longer run on Windows 10 LTSC. This means no connecting to O365 services from Office on those desktops.
Microsoft's statements have long been if it's a user's "daily driver" machine LTSC is not appropriate. I would expect them to get more "forceful" about this as time goes on.

A grim bloody fable, with an unhappy bloody end.
I was guilty of putting LTSB/LTSC on workstations when Win10 first came out. A lot of my unwillingness to use the normal builds was a misunderstanding of how the shorter-term-supported releases would be supported: I thought we'd be doing the equivalent of a "service pack" update to the OS twice a year. And given how temperamental some of the software we run is, it sounded like a recipe for bi-annual scheduled-unscheduled outages.

But yeah, that's not the support cycle on the releases. Once the department had time to dig into it we realized you can still stay on a short-term build for a good long time, and we got to switching. Fortunately you can do in-place upgrades of LTSC to standard editions without the need to re-install the OS. And the new builds have caused far fewer side-effects and software glitches than I expected.

Sorry, I'm running on a couple hours of sleep. Basically, I'm trying to find a way to compensate for deficiencies in an MECM task sequence that I'm not in a position to change. By the end of the task sequence, the target computer has been reformatted and mostly configured, but it's not domain-joined, and the only available accounts are the built-in Administrator account and an unused local standard account. Since the "add a work or school user" option appears to be unavailable from these accounts, I'm supposed to manually run sysprep to trigger the OOBE. During the OOBE, I sign in with Azure AD credentials, from which I can add other users as needed.

I'm not interested in going through the OOBE manually every time, so I've made an unattend file. The only part of the OOBE that I haven't been able to automate away yet is that initial AzureAD sign-in.

Hybrid Identity* for users, non-hybrid Azure AD Join for the computers in question.

*In case that term is narrower than I realize, what I mean is that users are synced between on-prem AD and Azure AD via Azure AD Connect.

Yeah, sorry, I couldn't remember the term for that. So I am pretty sure you can do what you're asking. I assume you don't need these laptops on the domain, so legacy AD just kind of exists for backend infrastructure and you're not using Kerberos auth for anything? I'm having a hard time wrapping my head around your use case, but yes, you should be able to do it. This article mentions Azure AD users specifically.

all your users should be sync'd between your prem AD and Azure ad. You might be thinking about white-glove (now called pre-provisioning) autopilot.

Basically takes your unattend.xml and puts it the cloud. (That is, if you have a tpm 2.0 chip and your devices are enrolled into intune...which you should do for all your AzureAD devices) Full zero-touch provisioning and no need to login at OOBE.

Yeah, the use-case seems weird because the situation is kinda dumb.

  • The laptops in question are loaners. Sometimes they're reserved in advance, and sometimes they're handed over to users on demand during walk-up requests. When the laptops are returned, they're formatted and re-imaged on-prem via ConfigMgr.
  • The laptops aren't joined to the on-prem domain to simplify pandemic-related scenarios where the machine might be off-site for weeks or months. This way, users who don't otherwise need VPN don't have to worry about connecting occasionally just to let the computer phone home.
  • For in-person on-the-fly requests, having the user go through the OOBE slows things down, so it's useful to have laptops on hand that have already gone through that step and just need the walk-up user's AD/AzureAD account added as a local admin.
  • I'm not a domain admin. I've got local admin rights on most domain-joined computers, but my access to most of MECM, Group Policy, Intune, etc. is read-only.
  • The guys who do have the necessary access are unlikely to make any changes I suggest in a timely fashion, so instead of doing any of this the right way, I'm stuck trying to do the best I can with the access I've got—hence the unattend file.

I'm no expert, but that's the same thing I see. Compare to the create new application operation where you'd point to an msi file.

Is there a definitive need to use Microsoft's name servers with your Azure AD tenant configuration or is it more of a convenience feature for managing DNS within the Azure portal?

Currently, DNS is handled via Network Solutions, but I'm wondering if there's a need for their name servers to make AAD/Intune work better in some way.

What's the first things to check with DHCP leases not showing up in DNS? Same server, it's an AD setup.

We have Cisco WiFi AP's, they were in there but a bunch were missing. I removed the leases, A and PTR records and restarted them all, they all got new leases but no DNS records were created. I made sure all the obvious settings for the scopes to register dns were set, but no luck.

The other scopes with workstations and phones work just fine.

Is it just one device? Have you tried running "ipconfig /registerdns"? Have you tried restarting the DNS service (on the one server, not on the DNS server) or the server itself? Is there an existing, corrupt DNS entry for the device in the DNS server?

I checked a bunch of other non-domain devices, and then I created a dhcpupdate service account. this must have been it because now they are showing up.

I saw this yesterday, but figured it wasn't it because the devices were in DNS before I started messing with it. I wonder if they were static records? Why would the MSP create static records for devices that get DHCP addresses?

Are you referring to Active Directory Lightweight services? That is a standalone LDAP role that is seperate from Active Directory. It allows you build a directory service independent of Active directory but use all the code that's active directory and LDAP friendly, say if you wanted a custom schema and attributes and didn't want to mess with Active directory. (spoiler: don't mess with active directory schema!)

Mostly used as an identity store to not keep usernames and passwords in your SQL database. Can be used as a identity source for AD FS. Also can sync data from Active Directory.
