815 - Failed to connect.

Windows Vista Only - This error occurs only with Windows Vista. It "replaces" error codes 676, 678, 691 and 769 from Windows XP and earlier, and covers at least 4 different causes of failure to connect. This error can occur on attempts to make a DSL connection. The actual detailed reason for the failure to connect does not show up on the standard Vista error screen, but is available if you look hard enough and includes:

  • Line is busy (for DSL the line isn't really busy, but the DSL server has a problem)
  • Remote Computer did not respond (there is a connectivity error)
  • Username or Password Error (the username and/or password specified for the DSL connection is incorrect or not recognized by the DSL server)
  • Destination Host Unreachable (networking or network card error)
