未下载 Microsoft 符号 - 404 错误

Question

Microsoft 符号服务器在线，但不知何故我无法下载任何个符号。

我试图将范围缩小到以下 POC。它应该只下载 aadtb.dll 的符号，但它 returns a HTTP_STATUS_NOT_FOUND.

symchk /v /r c:\windows\system32\aadtb.dll /s SRV*c:\symbols*https://msdl.microsoft.com/download/symbols

或者，我尝试使用以下不同的 Powershell 方法下载 pdb，但这也返回了 404 消息

$url = "https://msdl.microsoft.com/download/symbols/aadtb.pdb/BC45F7DA843249FFA96D9396BEE5F35D1/aadtb.pdb"
$output = "c:\test.pdb"

(New-Object System.Net.WebClient).DownloadFile($url, $output)
Invoke-WebRequest -Uri $url -OutFile $output
Start-BitsTransfer -Source $url -Destination $output

我仍然怀疑我这边有问题，但请注意，我确实在两台不同的机器上尝试过 3 个不同的 VPN 隧道，结果都是一样的。 上周五 10 月 25 日在一台完全不同的机器上工作。

在完全发疯之前，有人可以验证他们是否仍然可以下载符号，最好是我提到的符号吗？

kernel32.dll 和 ntdll 给出相同的结果 _{为简洁起见被删减}

symchk /v c:\windows\system32\kernel32.dll /s SRV*c:\symbols*https://msdl.microsoft.com/download/symbols

Answer 1

服务器上根本不存在该文件。

this可以帮到你吗？

Answer 2

它看起来像 Microsoft 方面的一些 SNAFU。所以，是的，就像@RbMm pointed out, send an email to WinDbgFb@microsoft.com to let them know. And maybe also tweet it to Andy Luhrs。请记住，这是一个小团队，他们可能要到星期一才能做任何事情（在美国。）
