Installing Symbols for Debugging System Call Crashes 

To debug a crash that occurs during a call to a system DLL or to a 3rd party library, you will often need system DBG or PDB files, which contain symbols for Windows DLLs, EXEs, and device drivers. You can obtain these symbols from several places:

  • The Visual Studio CD-ROM contains symbol files for selected versions of Windows.

  • The OS Support Tools CD-ROM contains symbol files for Windows 2000 and Windows XP.

  • You can download the latest symbols for your version of Windows from symbol packages.

  • You can download symbols automatically from the Microsoft symbol server at or from a local symbols server that is set up on your intranet.

    ( is for symbol download only. It is not browseable.)

    For details, see Using a Symbol Server.

  • The 3rd party vendor may make the symbols available.
