    '?', hexadecimal value 0xDC55, is an invalid character.
  • When you parse the XML data in an application by using the SqlClient provider, you receive the following error message:
    '?', hexadecimal value 0xDC55, is an invalid character.
  • When you parse the XML data in an application by using the SQLNCLI10 provider, you receive the following error message:
    Protocol error in TDS stream Communication link failure
  • When you parse the XML data in an application by using the SQLOLEDB provider, you receive the following error message:
    [DBNETLIB][ConnectionRead (recv()).]General network error. Check your network documentation.
