Code:
Listening on: (DESCRIPTION=(ADDRESS=(PROTOCOL=ipc)(PIPENAME=\\.\pipe\EXTPROC0ipc)))
Error listening on: (DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=VALUED-CB7D4C82)(PORT=1521)))
TNS-12532: TNS:invalid argument

TNS-00502: Invalid argument
32-bit Windows Error: 22: Invalid argument
No longer listening on: (DESCRIPTION=(ADDRESS=(PROTOCOL=ipc)(PIPENAME=\\.\pipe\EXTPROC0ipc)))

Problem is with the Protocol - correct,save and run.
