Я хочу подключиться к домену Active Directory через VPN-соединение. Я использую Windows 10 и подключаюсь с помощью VPN-подключения Windows. Я понимаю, что для того, чтобы сделать это, я должен подключиться к VPN перед аутентификацией и выполните следующие действия:
где я получаю повесил трубку, что VPN-соединение не доступно на экране входа в систему, как показано здесь (Я понимаю, что это через Windows 7, но идея та же, и связь должна появиться):
автор статьи утверждает:
«также очень важно установить флажок» Разрешить другим людям
используйте это соединение», так как скоро у вас будет учетная запись домена, которая будет
требуется доступ к этому VPN-подключение.»
однако, когда я пытаюсь установить этот флажок, я получаю это:
«Не удается разрешить общий доступ. Ошибка 87: параметр задан неверно»:
Я где-то читал, что мне нужно включить раздельное туннелирование, чтобы это работало, поэтому я следовал этим инструкциям:
http://eyonic.blogspot.com/2016/06/how-to-enable-vpn-split-tunneling-in.html
Это не помогло решить проблему. У меня все еще нет ссылки для подключения к VPN до входа в систему, и я ошибка 87. Как решить эту проблему?
When trying to enable Internet Connection Sharing on a VPN connection (windows build in VPN client), it can’t be done and returns an error information:
«cannot enable shared access. error: 87 the parameter is incorrect»
This BUG has been brought to Windows 10 for a long time , probably since Version 1607, and still remains unfixed untill now (Version 1709, Build 16299.192)
In early windows 10 version such as 1511, this function works fine.
Here comes the most weird thing. I’m pretty sure about my OS is fine. I’ve reinstalled my windows 10 system and the sharing function is just fine on other network adapters such as ethernet or wi-fi adapter, even a 3rd
party VPN client adapter.
The function just can’t work on windows build in vpn client (WAN Miniport adapter) .
I hope Microsoft engineer can fix this bug soon . I have been waiting a long time for this .
PS:
1 The VPN connects smoothly. There is no VPN connection problem
2 I have tried to reinstall Version 1511 and Version 1709 on the same hardware to exclude any other influence.

VPN error 87 typically occurs on Windows operating systems and is related to the configuration of the VPN client. This error occurs when a user tries to establish a VPN connection using the «route add» command, but the syntax is incorrect, or there are invalid parameters. The «route add» command is used to add a new route to the routing table of the VPN client. The client can route traffic to a specific network through the VPN tunnel.
To resolve VPN error 87, the user should verify the syntax of the «route add» command and ensure that the parameters used are correct. The correct syntax for the command is:
route add <destination_network> mask <subnet_mask> <gateway_IP_address>
For example:
route add 192.168.1.0 mask 255.255.255.0 10.0.0.1
In this example, the destination network is 192.168.1.0, the subnet mask is 255.255.255.0, and the gateway IP address is 10.0.0.1. It’s also important to note that VPN error 87 can be caused by other factors, such as conflicts with other networking software or outdated VPN client software. In such cases, updating the VPN client or disabling conflicting software may be necessary to resolve the issue.
The importance of using a VPN
VPN (Virtual Private Network) is an important tool in today’s world as it offers several benefits to its users. Some of the key importance of VPN are:
Protecting online privacy
VPNs encrypt users’ internet traffic and hide their IP addresses, making it difficult for others to track their online activities. This helps protect their online privacy from governments, ISPs, and other third-party entities.
Securing public Wi-Fi
Public Wi-Fi networks are often insecure, making it easy for hackers to intercept transmitted data. A VPN can help secure these connections and protect users from attacks.
Accessing geo-restricted content
Some online content is only available in certain regions or countries. Using a VPN, users can change their virtual location and access this content from anywhere.
Avoiding censorship
Some countries restrict access to certain websites or online services. VPNs can help users bypass these restrictions and access the content they want.
Enhanced security
VPNs provide users with an additional layer of security, especially when accessing sensitive information like financial transactions, passwords, or personal information. Overall, VPNs are an important tool for online privacy, security, and freedom in today’s interconnected world.
How to solve VPN error 87
VPN error 87 is typically related to the configuration of the VPN client and occurs when there are issues with the syntax used in the «route add» command. Here are the steps to resolve this error:
Verify the syntax of the «route add» command
Ensure the syntax of the «route add» command is correct and the parameters used are valid. The correct syntax of the command is:
route add <destination_network> mask <subnet_mask> <gateway_IP_address>
For example:
route add 192.168.1.0 mask 255.255.255.0 10.0.0.1
Check for conflicts with other networking software
VPN error 87 can also occur due to conflicts with other networking software. Disable any other VPN software or firewalls that may be causing the issue.
Update the VPN client software.
Outdated VPN client software can also cause VPN error 87. Ensure you are using the latest version of the VPN client software.
Check the VPN configuration settings.
Verify that the VPN configuration settings are correct and match the settings provided by the VPN service provider.
Restart the VPN client and the computer.
If the above steps do not resolve the issue, try restarting the VPN client and the computer. If the issue persists, contact the VPN service provider for further assistance.
Last word
VPN error 87 can happen for different reasons. First of all, check for possible bugs. By doing the methods we reviewed in this article, you can solve VPN error 87. If your problem persists, try another VPN program or contact the company of the VPN provider.

Hi,
Solved this issue myself but saw no mention on here.
I recently moved to a new server where I have Algo VPN but kept getting a weird error «parameter is incorrect» when connection to it.
SOLUTION:
If you install the Windows 10 ps1 file (as noted in the installation instructions) and when you try to connect is says «parameter is incorrect» then so the following:
- Clear the Networking caches
Run windows cmd window (click windows start menu, type ‘cmd’, right click on ‘Command Prompt’ and select «Run as Administrator»).
type command below
netsh int ip reset
then type
netsh int ipv6 reset
then type
netsh winsock reset
Restart your computer.
-
Reset Device Manager adaptors
Open Device Manager
Find Network Adapters
Uninstall WAN Miniport drivers (IKEv2, IP, IPv6, etc)
Click Action > Scan for hardware changes
The adapters you just uninstalled should come back
The VPN connection then works.
Hope this helps someone.

Worked like a charm. Thank you dguido.
It works but is there an easier fix? I don’t like to do this on all my machines
What causes this issue?
Parameter Incorrect is a problem I have and followed the fix instructions.Still getting the same message and starting to come to the conclusion that there is a corrupt file on the system.Any ideas from any one who has been tormented from this would be greatly appreciated. In the meantime good luck and keep up the brilliant work.Kind regards to you all.

First problem I meet is modem problem. I first click the «reset network» in Setting -> Network and then restart PC, but problem turn to same with you(Parameter Incorrect). Then I tried this solution, after 1st step, the problem still occur. But after 2nd step the problem finally resolved.
This is useful to me, thank you.
AWESOME! Just signed up to thank you! This was so struggling as malfunctioning VPN is equivalent to death in China. You are my savior and make my day.
You are a godsend! Thank you so much!
@alexmelSC registered just to say thanks! After spending an hour trying to mirror my desktop to my laptop (which worked fine) and spending a few minutes with IPVanish chat support to no avail, I finally stumbled across this thread and lo and behold… it worked! Big thank you to you. Much appreciated.
Absolute genius!!! Many thanks, finally solved this : )
Thank you so much. I have been on hours trying to get this working. Your post has made me so happy!!!!!!!
Adding one more vote of thanks…just tried this after a lot of time wasted on other efforts and this worked immediately…thumbs up!
Thank you so much , it helped a lot
Banging my head against the wall with this until I found your instructions. Boom, connection on every protocol now. After days of looking you saved me… thank you.
Thank you very much!! it’s worked!!
I made a Github account just to say that this worked great for me. Thanks bro
Thank you! I had many troubles post KB4557957 (Windows 10 v 2004) & one of them was connecting to work VPN on IKEV2. Man, don’t have words to appreciate your tip. I’m a developer, got three different database technologies, half dozen development tools installed and configured…and was going to format the goddamn thing & landed on your solution!
Thanks!!!! I was thinking also of reinstalling everthing! It works perfectly!
Worked like a charm! Thank you!!!
I had this issue, nothing related to algo, but you just save me a lot of time, after some wrong troubleshooting. thanks so much mate!
You have my gratitude! I hope you’re doing well
I am genuinely surprised people still find this useful. Merry Christmas all.
Very useful note, thanks bro.
Thanks.
Microsoft humor strikes yet again,
Made my VPN working — great
Thank you so much for updating this and telling us your solution! The first one helped my overall internet speeds and the 2nd set of steps actually fixed my VPN. Thank you so much!
@alexmelSC : You made my day 👍.
One remark: My first try was to only delete the WLAN Miniport drivers that are relevant for me: IKEv2 and PPPOE.
This was not sufficient: After removing all WLAN Miniport drivers both protocols work again.
Thanks again!
Thanks for your post, «The parameter is incorrect.» error had me baffled with Microsoft’s AO VPN, I’d tried so many things and I’d got to the stage of almost giving up and rebuilding my computer (Windows 10 20H2 Enterprise). I’d already tried to uninstall and reinstall the IKEv2 WAN Miniport, but seeing your post I also uninstalled IP and IPv6 and hey presto, no reboot, Device and User Tunnels now connecting and back on AO VPN.
Thanks…
Reset Device Manager adaptors
Open Device Manager
Find Network Adapters
Uninstall WAN Miniport drivers (IKEv2, IP, IPv6 etc) <- I only needed to do IKEv2, IP and IPv6.
Click Action > Scan for hardware changes
The adapters you just uninstalled should come back
For those, who still get error 87 after clearing networking caches, check that Internet Connection Sharing ICS service is running.
It works, thank you so much.
man, you just saved me from a mental health institute
You’re still saving people’s lifes, man! Step 2 worked for me. Thank you very much!
Thanks, you just saved me a long drive to the office
Still works like a charm!
Thanks, this works for me. I spent 2 hours to find the issue. But I fixed it in 5 minutes by your solution. God bless you.
This helped me as well.. Crazy that this is been a 3 year issue? Thanks for the advice!
