Question

Windows 10 automatically changing sign-on settings for VPN

Maritza Pearson 11

Hello, I am having intermittent problems with the built in Windows 10 IPsec VPN client. When using it with our Meraki Firewall, it will automatically change the sign on from User Name and Password to General Authentication when the adapter settings Authentication Protocol is set to PAP. And when you change it back to Username and Password it will change the adapter settings Authentication Protocol to MC-CHAP v2. Why is Windows 10 doing this? This is not a Meraki issue. It doesn't make these changes with Windows 7.

Just for test disable your Firewall and see if the problem persist?

Even when I bypass the firewall the same thing happens. @Anonymous That is exactly what happens. Windows 10 automatically switches the sign on method.

Have you set any policy in the Group Policy might enforce this behavior?
You may use gpresult /r to check if there is any policy might affect this behavior?

I concur, this anomaly happens in our environment too. It's inconsistent, meaning not every user has this issue and some go away after time.
The frustration is making a change to the adapter settings causes the login type to change from Username and Password to General Authentication ... gremlins be damned

It's 2024 and I'm having this same issue. Has there been any resolution? This is painful.

Hi!

Neither option worked for me.
Removing the last Windows updates helped me.
Updates WIN 10:

Update for Microsoft Windows (KB5008876)
Security Update for Microsoft Windows (KB5009543)
Feature Update to Windows 10 21H2 via Enablement Package (KB5003791)

Unfortunately, I didn't write down the update numbers on Windows 11 that I deleted.
I will be glad if it helps someone!

I've got the same problem. Uninstalling those updates didn't change the behaviour. Have you found a solution?

Hello ViktorK,

I'm having this exact same issue - could you provide me the steps you took to find and use the RASPHONE client?

Thanks,
Geoffrey Haselden

Hello Geoffrey,

it's in your Windows/System32 folder. Go to the folder and start typing rasphone - and it will come up.

Viktor K 1

I've done an extensive research and the only walkaround that sometimes works is using an old RASPHONE client (look for it in windows/system32 folder). You can play with the settings and it will enforce these checkboxes. Then you can save a shortcut for the future use.

Answer 4

Hi ,

Based on my understanding, you configure the adapter settings Authentication Protocol as below:

Then it will automatically change to General Authentication method:

In such case, we need to trace log to analyze the cause. However, analysis of tracing log is beyond our forum support level and due to forum security policy, we have no such channel to collect user log information. So we recommend you open a case with MS Professional tech support service, they will help you open a phone or email case to Microsoft, so that you would get a technical support on a one-to-one basis while ensuring private information.

No, there are no group policy settings that are enforcing this. Others have reported the same issue, like CandyLuo-MSFT.
