Windows 11 Error message 0x00000709 while connecting to shared printer after Update windows 11 25H2. How to Solve the Problem

To resolve the error message 0x00000709 while connecting to a shared printer after updating to Windows 11 version 25H2, you can try the following steps:

1. Check Printer Name: Ensure that the printer name is correct and that the printer is connected to the network.
2. Registry Changes: You may need to modify the registry settings. Use the following commands in an elevated Command Prompt:

      reg add hklm\system\currentcontrolset\control\print /v DnsOnWire /t REG_DWORD /d 1
      reg add hklm\system\currentcontrolset\services\lanmanserver\parameters /v DisableStrictNameChecking /t REG_DWORD /d 1
      reg add hklm\system\currentcontrolset\services\lanmanserver\parameters /v OptionalNames /t REG_SZ /d "aliasname"
   

   Note: For third-party DNS providers, you may need to use QWord instead of DWord.
3. Update Drivers: Ensure that your printer drivers are up to date. You can download the latest drivers from the manufacturer's website.
4. Check Network Settings: Verify that your network settings allow for printer sharing and that the printer is set to be shared on the network.
5. Reinstall the Printer: If the issue persists, try removing the printer and then adding it again to see if that resolves the connection issue.

If these steps do not resolve the issue, you may need to consult additional resources or support for further assistance.
