Q. What does error 815 in Windows Vista mean?
A. This error appears when there is no connection to our PPPoE server
available. This is commonly caused by either a disabled account
with NTT or a faulty line or NTT device. Please contact NTT if you are receiving this error message to confirm the status of the account with them.
If
the account is active and working with NTT, this error can occur when
the computer is not connected directly to the NTT device and is
connected to a router instead. If this is the case, please connect the
cable to the NTT device directly and try connecting again.
If you continue to have receive this error message when trying to connect, please contact us
