Resolution

To resolve these issues, use the following commands:
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 have to use QWord instead of DWord. Therefore, you should use QWord instead of DWord for these commands.
