Password Reset

I studying for CCNA and am setting up a lab. I am using a Cisco 1721 router in my test environment. I do not know the password for en mode. I am only able to successfully get into user mode. Do I have to be in priv exec mode to reset priv password? Can I reset to factory defaults without being in priv exec mode if that is what it comes down to? If yes, how do I reset this router back to factory defaults?

Thank Ya Very Much!!

    google is your friend bro... and yes, it also appears that your question was answered in an earlier post.

    just send a break command when starting up your router to enter rommon... from there enter

    rommon 1> confreg 0x142
    rommon 2> reset

    once restarted:

    Router>en
    Router#erase start-up config
    Router#conf t
    Router(Config)#conf register 0x2012
    Router(Config)#end
    Router#copy run start
    Router#reload
