(Doc ID 2128792.1)

Last updated on JULY 05, 2016

Applies to:

Oracle Net Services - Version to [Release 12.1]
Microsoft Windows x64 (64-bit)
The install has been done on a Primary Domain Controller.


Remote connections via the 12c Listener fail consistently with the ORA-12518 error.
ORA-12518: TNS:listener could not hand off client connection


 This is likely a new installation OR the Windows server has recently been promoted to a Primary Domain controller or PDC.
