LKBEN10933: Windbg debugging symbols cannot be loaded because of a proxy


You need debugging symbols but they cannot be loaded because of a configured proxy




First of all you can make the loading of the symbols noisy with the following command:

!sym noisy

Now WinDbg will show you how it is resolving the symbols and will show you errors as well.

Now you should check your symbol path. e.g.


Please make shure it is right. If your system cannot download any symbols try to set the variable _NT_SYMBOL_PROXY=yourproxy:yourport. e.g.


Try to reload with the .reload command and test with lm. (list loaded modules)
