I have a dump collected from a system that i dont have access to. Opening the dump in windbg shows incomplete callstack due to missing kernelbase dll. It should have been downloaded from microsoft symbol server but it has failed. This is a very frequent issue for system dlls unable to download. This is causing a lot of problems as we are getting incomplete callstacks for crashes and unable to group them. Please root cause why the system dlls are missing from MS symbols server so frequently.
The dll missing in my dump :

Hello @Dev Stability ,
Welcome to Microsoft Q&A forum.
I notice that you added Visual Studio Debugging tag. Not very sure, but may I first confirm if you use Visual Studio?
In VS => Tools => Options => Debugging => Symbols, sometimes, selecting/checking the "Microsoft Symbol Servers" option is useful.
I use windbg but did not find any such tag. But same issue should be observable in VS as well.
I have already set the symbol paths for msdl in env variable __NT__SYMBOL_PATH. Symbol path is not the problem.
Since Win 8.1 reached EOL and is out of support I wonder if MS has removed the symbol files from the server.
