In Windows 10 1903/1909 I’ve discovered a number of unusual bugs associated to configured VPN connections. The first downside: when making an attempt to hook up with a distant VPN L2TP server, a VPN connection hangs within the “
Connecting to...” state. At the identical time, the immediate for VPN credentials doesn’t seem, and after some time the connection is terminated with none error message.
Windows 10 VPN by no means Prompts for Username/Password
It appears that on some purpose a immediate to enter person credentials is blocked in Windows 10 VPN connection dialog. As a consequence, the VPN connection can’t be established.
There is a workaround for this problem. Try to make use of the nice previous
rasphone.exe software to ascertain a VPN connection. The rasphone.exe software must be acquainted to anybody who has used a dial-up connection in Windows (it’s nonetheless current in trendy Windows 10 variations).
- Start the software: Win+R ->
- Select your VPN connection and click on the “Connect” button;
- Then a typical dialog to enter person credentials for the VPN connection seems. Press Connect;
- The VPN tunnel should be efficiently established.
To make it extra handy in your customers, chances are you’ll place the rasphone.exe shortcut on the desktop. To join mechanically, you may specify the title of your VPN connections within the shortcut settings as follows:
C:WINDOWSsystem32rasphone.exe -d "VPN Name" (you may get the VPN connection title from the Control Panel -> Network Adapters and put quotes round it if it comprises areas).
It is attention-grabbing that the issue seems solely with L2TP connections (even when the = 2 registry parameter is configured). Another VPN connection on the identical pc utilizing PPTP protocol and MS-CHAP v2 authentication works effective.
Always On VPN RasMan Error in Windows 10
Another downside happens with the Always on VPN (AOVPN) connection to a company community. When you initialize such VPN connection, the RASMAN (Remote Access Connections Manager) stops, and the occasion with the Even ID 1000 and the next message seems within the Application Event Log:
“Faulting utility title: svchost.exe_RasMan…”, “Faulting module title: rasmans.dll”, and “Exception code: 0xc0000005”.
