perhaps after lan setting you changed your pc name or
make sure you have installed in oracle enterprise server ie option one during installtion.

Change all (HOST=...) entries in your TNSNAMES.ORA and LISTENER.ORA files to the new machine name/ IP address and restart the listener.

12545, 00000, "Connect failed because target host or object does not exist"
// *Cause: The address specified is not valid, or the program being
// connected to does not exist.
// *Action: Ensure the ADDRESS parameters have been entered correctly; the
// most likely incorrect parameter is the node name.  Ensure that the
// executable for the server exists (perhaps "oracle" is missing.)
// If the protocol is TCP/IP, edit the TNSNAMES.ORA file to change the
// host name to a numeric IP address and try again.

Best regards.
