Microsoft符号未下载 - 404 错误

Question

Microsoft符号服务器已联机，但不知何故，我无法下载任何符号。

我试着把它缩小到跟随POC。它应该只下载aadtb.dll的符号，但它返回一个HTTP_STATUS_NOT_FOUND。

symchk /v /r c:windowssystem32aadtb.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

我仍然怀疑自己有问题，但请注意，我确实在两台不同的机器上尝试过，并通过了3个不同的VPN隧道，结果都是一样的上周五，25/10在一台完全不同的机器上工作

在完全疯狂之前，有人能验证他们是否还能下载符号，最好是我提到的符号吗？

kernel32.dll和ntdll给出了相同的结果_{为简洁起见剪切了}

symchk /v c:windowssystem32kernel32.dll /s SRV*c:symbols*https://msdl.microsoft.com/download/symbols

它看起来像是微软的SNAFU。所以，是的，就像@RbMm指出的那样，给[e-mail]让他们知道。也许也可以发推给Andy Luhrs。请记住，这是一个小团队，他们可能要到周一才能做任何事情(在美国(
