Windows内置的SSTP VPN客户端拨号失败显示“由于吊销服务器已脱机，吊销功能无法检查吊销”的解决办法：
Open the Windows Registry Editor on you computer (regedit)
Find the following registry path: HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Sstpsvc\Parameters
Add a new registry value (REG_DWORD) under called “NoCertRevocationCheck”.
Set the key value to 1 (Default is 0)
NoCertRevocationCheck
Registry path: HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Sstpsvc\Parameters
Name: NoCertRevocationCheck
Value: 1
Data type: REG_DWORD
不需要重启，只需要重新拨号即可
