Hi all,
It's been along time since i posted here, i just want to share something with you, a couple of days ago i wanted to install Oracle9i on a windows server for testing purpose, while using Database Configuration Assistant and during the creation of the instance i got ORA-01041: internal error. hostdef extension doesn't exist.

to tell you the truth i tried many things and it took me sometime to figure out that i have to set the 'SQLNET.AUTHENTICATION_SERVICES' parameter in the sqlnet.ora file to (NONE).

i just thought i would share this with you guys.
