How to get OS information from minidump crash?

I am trying to debug a minidump crash dump. How can I get to know the OS so that I may download related Microsoft Symbols?

I am using Visual studio and windbg.

I haven't seen that syntax for the MS symbol server before, I usually just do:

.symfix h:\symbols .reload

From within the debugging session. It automatically sets your symbol search path to point to the symbol server so you don't have to worry about remembering the path.

vertarget will tell you the target machine of the minidump.

The dump contains enough information so that the symbol server client will load download and use the symbols that match the executable and dlls.

I.e. define environment variable _NT_SYMBOL_PATH to something like:

symsrv*symsrv.dll*h:\Symbols*http://referencesource.microsoft.com/symbols*http://msdl.microsoft.com/download/symbols

where h:\symbols is a writeable folder. The debugging tools will do the rest.

Note:

  • You need to do it this way because patches, including service packs, also change the version of the symbols.
  • The first download location is used for .NET with source server, if not working with .NET that can be removed.
