AVD Client on Windows 7 stopped working today (Error code: 0x3000008)

[feeneymi]

We have a number of users of AVD still on Windows 7 client PCs. Just today they all stopped working and unable to connect to any resources. Windows 10 client PCs are ok. I have reinstalled and reset the AVD client and subscribed but the issue persists on connecting to any resource displayed. Error displayed:

Hi,

Microsoft Disable TLS 1.1 and 1.0 support from azure virtual desktop.
you can run this powershell script for enable TLS 1.2 on Windows 7 and Windows 8 (be careful don't execute this on Windows 8.1 or higher).

https://docs.microsoft.com/en-us/azure/active-directory/hybrid/reference-connect-tls-enforcement

Yes, this is the fix, we have come across multiple windows 7 machines with this issue.

@jeep92 , very helpful. Thanks. I've had the same problem with another customer. Looks like Microsoft is disabling earlier TLS versions in waves? This problem was already reported 1st of July for my customer.

Was there any official announcement done by Microsoft towards their AVD customers?

[#5]

No official announcement and the support (from azure portal and twitter) don't know this problem 😅

@jeep92 

Is there a fix that you know of for windows 8.1? I have a client who is using that version of windows and You said not to run that script on that version. 

I do have another client on windows 7 so I will try the above fix for that one. 

Thanks for your help! 

Cheers, 

James

The .NETFramework part applies to (and required) for Windows 8.1 too

[HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\.NETFramework\v4.0.30319]
"SystemDefaultTlsVersions"=dword:00000001
"SchUseStrongCrypto"=dword:0000001

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\.NETFramework\v4.0.30319]
"SystemDefaultTlsVersions"=dword:00000001
"SchUseStrongCrypto"=dword:00000001

In the internet option tls1.2 is checked the above powrshell script does anything extra then enabling tls1.2?
