RE: ORA-12638: Credential retrieval failed URGENT!!!!

 Look in C:\oracle\ora81\network\admin\sqlnet.ora for the line

SQLNET.AUTHENTICATION_SERVICES= (NTS) This is why Oracle is trying to retrieve user information from the domain. I ran into this when I had a laptop plugged into the network, and I installed Oracle onto it, then tried to access Oracle when disconnected from the network. Off the top of my head, I changed it to NONE and then I was all set.

->Action: Enable tracing to determine the exact error.

did you enable tracing? if so what's the output?

->
->I would like to guess authentication service has problem since network
->config change. We have similar situation before. Change ip address and
->keep hostname without any problem

are you sure you're accessing by hostname and that the hostname is resolving correctly?
