Expired certificate warning while connecting to Windows machine using RDP:
Looks like latest Windows 2022 and 11 updates broke certificate reissuing mechanisms. It can be seen as expired certificate warning when connecting with RDP to windows machine.
According to this manual: https://docs.rackspace.com/docs/rdp-connection-failures-expired-self-signed-certificate the problem is with the “f686” file/ It shoud be replaced with the new one by Remode Desktop Services when needed, but somewhy it is not being replaced.
With help of this manual https://learn.microsoft.com/en-us/previous-versions/windows/it-pro/windows-server-2008-R2-and-2008/cc753525(v=ws.10)?redirectedfrom=MSDN I created Powershell script that can be placed in domain Group Policy and started at next reboot or this script can be manually run by admin on the machine that needs this fix:
Fix-Expired-RDP-Certificate.ps1:
net stop "TermService" /y
takeown /F "C:\ProgramData\Microsoft\Crypto\RSA\MachineKeys\f686*"
icacls "C:\ProgramData\Microsoft\Crypto\RSA\MachineKeys\f686*" /grant administrators:F /t
Get-ChildItem "C:\ProgramData\Microsoft\Crypto\RSA\MachineKeys" | foreach{ Rename-Item $_.FullName -NewName ($_.FullName + "-old")}
net start "TermService" /y
I prefer to keep old files and not delete them, but here is a tested broken f686* remove command just in case:
Remove-Item -Path "C:\ProgramData\Microsoft\Crypto\RSA\MachineKeys\f686*" -Force

I’ve found VirtualHere usb sharing software:
https://www.virtualhere.com/
There is a free of charge alternative so you can start free of charge server and use the client specified above also free:

or use alternative client (Windows only)

Lighttpd info
Rewrite rules:
https://stackoverflow.com/questions/5059860/lighttpd-url-rewrite
Add a rule specifically for paths with a trailing slash:
url.rewrite = (
"^/framework([^?]*/)(\?.*)?$" => "/framework$1index.php$2",
"^/framework/([^?]*)(\?.*)?$" => "/framework/$1.php$2"
)
And here’s a breakdown of how the regular expression works:
^ // Match the beginning of the string
/framework // Match any string starting with "/framework"
( // Open the first group ($1 in the right hand side)
[^?]* // Match zero or more characters that are not '?'
/ // Ending in '/'
) // Close the first group
( // Open the second group ($2)
\? // Match a '?'
.* // Match zero or more characters
) // Close the second group
? // Match the second group exactly once or not at all
$ // Match the end of the string
Firefox
Restore previous session after closing Firefox windows and leaving another window open:
– close Firefox and/or don’t open if you just find that you’re in trouble
– go to %AppData%\Mozilla\Firefox\Profiles\YOUR-PROFILE
– find sessionstore.jsonlz4 and rename if to sessionstore.jsonlz4-old
– go to %AppData%\Mozilla\Firefox\Profiles\YOUR-PROFILE\
– copy all files from there to some temporary directoy
– copy one of those files to %AppData%\Mozilla\Firefox\Profiles\YOUR-PROFILE
– rename that copied file to sessionstore.jsonlz4
– try to open Firefox and see if your tabs are restored
– if not or not all, try another file
There is a good tool to recover information from the .jsonlz4:
