Windows Update error on Windows server 2019.
A much simpler solution may be to stand up a new one for replacement.
I'd use dcdiag / repadmin tools to verify health correcting all errors found before starting any operations. Then stand up the new 2019, patch it fully, license it, join existing domain, add active directory domain services, promote it also making it a GC (recommended), transfer FSMO roles over (optional), transfer pdc emulator role (optional), use dcdiag / repadmin tools to again verify health, when all is good you can decommission / demote old one.
I have a lot of Windows 2019 Domain Controllers and I try to repair the Windows without reinstall a new Server. Exist some possibility , some tool that I can run to fix the components error.
I wait your comments.
None beyond what you already mentioned. May need to rebuild the problematic ones one-at-a-time. You can also start a case here with product support.
