[MAJOR ISSUE] b20257, b20262 DNS Server service keeps crashing 0x0374
Dear Server Insider team,
I am facing the following issue starting with build b20257
DNS Server service keeps crashing and stopped on all ADDS DCs consisting of only hardware and Hyper-V ADDS Servers.
Effectively the domain becomes unuseable. It seems that the crash occours every time a DNS update is incoming
affected builds: Windows Server vNext SAC + LTSC starting with b20257, b20262
unaffected builds: Server vNext SAC + LTSC b20251 or earlier
Scenario:
3 DCs, 1 Site, Server vNext SAC (2 VMs), LTSC (Hyper-V Server, SET Switch)
Reproducible: yes
Scope: Affects all ADDS Domain Controllers (hardware or physical)
exemplary log:
DNS Service keeps crashing (seems like it does so on every incoming DNS update request).

When did the issue appear:
after upgrade to 20257.
- I now have that build and it does seem to cure the DNS issues. Thanks"
- Thomas LeeBrass ContributorI have 20270 and this bug has re-surfaced. I can not keep the DNS Service running.
Thomas Lee that's unfortunate. Have you tried b20282 yet? It kept being stable on 20270 for me on 3 VMs and one hardware ADDS DNS

Eldencan confirm all Server LTSC GUI / Server Core SAC AD DS DNS are working fine now after IPU to b20270!
Thanks for transparent communication and quick fix!

I'm experiencing the same. The DNS server goes offline after any Active Directory install.
OS Build 20257.1000
Performed multiple installs and attempts, all with the same result (attached).
Installed under Hyper V running the same Insiders build of Server. And the other a Windows 10 19042.630.- Elden_Christensen

Thank you for reporting this issue! We have a fix to address this issue and it will be available in the next Windows Server Insiders build.
Thanks!
