Oracle 11g Win32 Installation - Unable to Retrieve Credentials

I just installed Oracle 11g on my personal notebook, running WinXP SP3 and had the strangest of problems :)

While creating the DB, I got this error, "Unable to Retrieve Credentials" Well here is what I did:

1. Install Oracle 11g as just Software and no DB Creation
2. Update the SQLNet.ORA and changed the Authentication to (NONE)
3. Using Oracle Net Configuration Assistant, created the default Listener
4. Using Oracle Database Configuration Assistant to create a DB Instance

And it worked fine! The Authentication = (NTS) does not seems to work for me in 11g!

Hope I helped some one somewhere ;)
