Administrator password stopped working after installing AD

[spideron]

Hey,

I've added the role of domain controller to my windows 2008.
After the windows rebooted, my administartor's password in not working, getting a message of incorrect password.

Any ideas?

Thanks.

Might be because you had securew passwords disabled. Try changing the password to a secure password.

Thanks for the suggestion.
But I can't login to do any changes.
Any other ideas?

Thanks.
