Hello,
Just want to throw my two cents...
I also received the same 'fatal error' message: Fatal NI connect error 12638, connecting to:
Following the suggestion of changing the SQLNET.ORA which can be found on the client Windows if you do a search, you'll see:
SQLNET.AUTHENTICATION_SERVICES = (NTS)
I tried changing it to
SQLNET.AUTHENTICATION_SERVICES = (NONE), but Windows won't allow me to overwrite, so i simply moved this file out of the directory path and voila, it worked!
Just so you know, my issue was this: I get the Fatal message when my Crystal Reports app ver 2010 tries to log into one of our Oracle DB, but when I use Oracle Developer app using the same credentials, it would work fine or if I use CMD prompt to log into the ORA db it would be ok.
