Containerized Azure Data Factory Self-Hosted Integration Runtime works on Server Core `ltsc2019` build 17763.8511 but not 17763.9020

[MarkFGarner]

Summary

We build a Windows container image FROM mcr.microsoft.com/windows/servercore:ltsc2019 that installs and runs the Azure Data Factory Self-Hosted Integration Runtime (SHIR), based on Microsoft's reference sample (Azure/Azure-Data-Factory-Integration-Runtime-in-Windows-Container).

An image built while the base resolved to 10.0.17763.8511 works — the SHIR node registers and reports Online in Data Factory. An image built while the base resolved to 10.0.17763.9020 does not — the SHIR node does not come online. The Dockerfile, scripts, and SHIR installer are unchanged between the two builds; the base OS build is the only difference.

We have not determined the underlying cause and are not attributing it to any specific component — reporting the observed difference in case it is a known change or expected behavior.

Environment

	Value
Base image	mcr.microsoft.com/windows/servercore:ltsc2019
Base build where it works	10.0.17763.8511 (KB5078752)
Base build where it does not work	10.0.17763.9020 (KB5099538)
Host	Azure App Service for Containers (Windows)
Workload	Azure Data Factory Self-Hosted Integration Runtime, installed via IntegrationRuntime.latest.msi

Observed behavior

• Image built on base 17763.8511 → SHIR node registers and shows Online.
• Image built on base 17763.9020 (identical Dockerfile, scripts, and SHIR installer) → SHIR node does not come online.

Steps to reproduce

1. Build a Windows container image FROM mcr.microsoft.com/windows/servercore:ltsc2019 that installs IntegrationRuntime.latest.msi and registers a SHIR node (per the reference sample above).
2. Run it with a valid SHIR auth key on base build 17763.9020 and observe the node does not come online.
3. Build the identical image on base build 17763.8511 and observe the node comes online.
