No websymbols despite _NT_SYMBOL_PROXY and !sym prompts

[Arne Ludwig]

Hello Experts,

I'm using WinDBG (6.2.13.0) and have trouble loading
symbols from the web. I am behind a firewall, so I set:

_NT_SYMBOL_PATH=SRV*C:\WebSymbols\*http://msdl.microsoft.co
m/download/symbols
_NT_SYMBOL_PROXY=192.168.1.1:80

In WinDBG I have set !sym prompts and !sym noisy, but
there is no prompt. Consequently I get the following and
the .pdb file contains the "authentication error" from the
proxy server:

lkd> .reload
Unable to read head of debugger data list
Connected to Windows XP 2600 x86 compatible target, ptr64
FALSE
SYMSRV: ntoskrnl.pdb from
http://msdl.microsoft.com/download/symbols: 0 bytes -
489DBGHELP:

1\ntoskrnl.pdb - file system or network error reading pdb
DBGHELP: ntoskrnl.pdb - file not found
*** ERROR: Symbol file could not be found. Defaulted to
export symbols for ntoskrnl.exe -


What else do I have to do?

Thanks and best regards,

Arne

It appears that the newest version 6.3.17.0 of WinDBG now
uses the IE proxy settings. Do not use the
_NT_SYMBOL_PROXY variable and it will work fine even with
authentication.

Thanks Pat.
