Hi Tomcat456​,

Though one, but I'll give it a shot non the less!

can you validate;

 

  • The XML structure if everything is fine?
  • Might be an existing profile cache

I know also that when copying thumbprints there is a 'hidden white' character at start of the line. You should check that one out as well (as this cost me a lot of time in the past)

 

If you have a corrupted profile you can try removing that with:

netsh lan delete profile name="Network" interface="Primary LAN Interface"

 

Also check if the certificate can be fetched:

Get-ChildItem Cert:\LocalMachine\Root | Where-Object { $_.Thumbprint -eq "96f2bf58b39db8b704a4dda8c5df456c725fce24" }

 

And check for dot3svc service:

Get-Service dot3svc (need to be running)

    It does appear like there's an issue with the XML indeed.

First of all, <name> does not appear to be a property of <LanProfile>, so <name>$ProfName</name> should be removed entirely. (LAN_profile schema elements - Win32 apps | Microsoft Learn)

Second, the <authMode>userOrComputer</authMode> is wrong.
It should be "machineOrUser". (OneX element - Win32 apps | Microsoft Learn)



You may also need the <PerformServerValidation>, <AcceptServerName>, and <TLSExtensions> tags as children of the <EAPType> tag.
Compare with an export of a manually created and correct profile.

    I've wrapped everything in a code block because this site didn't like me using tags (invalid html)
