I installed Oracle 11g, but I also had this problem on 10g.
Whenever I try to schedule a job or restart the DB it asks me for the Host Credentials as well as the DB credentials.
For some reason whatever host credentials I use it keeps tell me "Credential verification error: ERROR: Invalid username and/or password"
I have used the local administrator, my domain account that I installed it with, another local account I have created. All are local admins. I have also tried in this format as well gsoracle\administrator corp\aghajm etc.. Also just administrator..
I know the passwords are right. What could I be doing wrong?
