Since the latest Cumulative Update Windows Update (KB4022715) earlier this week we’re having problems with missing symbols on Windows 10 LTSB 14393. In particular, the symbols for NT do not appear to be available on the MS symbol server:
start end module name
fffff8035a814000 fffff8035b02c000 nt (export symbols) ntkrnlmp.exe
Loaded symbol image file: ntkrnlmp.exe

Translations: 0000.04b0 0000.04e4 0409.04b0 0409.04e4
Is there a recommended email address/contact to whom we can report missing symbols and get the problem rectified?
We’re working on making improvements to our symbol publishing process, but right now there’s a notable delay between when builds are available and when the symbols are available.
I’ve verified the PDB for NT that Michael pasted is being indexed and should be available in the next couple days.
Sorry for cross posting to both lists but it was mentioned that this should be resolved by now and as of the time of posting it still is not:
