|Do you mean that your actually booted to the CD and then went though all the install steps?|
You should have put a password in at the install time. What did you type?
If you mean booted to the cd then use jack jack or jack opensolaris I think. Then run startx.
"Best Practices", Event viewer, host file, perfmon, antivirus, anti-spyware, Live CD's, backups, are in my top 10
