I am in trouble !!!

Hi actually i have unix operating system in my office and i am working as a admisnistrator in my company
and when I installed unix on a system I had installed unix on maximum security..
but one thing happend with me last week that I changed my root password and after that I forget that..

and there is so much data of our company in file system and unix are not giving me the chance to log in as a root
so what is the method of breaking my password and log in as a root in my unix machine ..and unfortunately no user has so much permissions. All users have ordinary END user permissions..
so please kindly reply me as fast as possible coz i have to solve this problem ...

thanks

Can you boot the system from an install disk or alternate hard disk?  If so, you can mount the root filesystem and modify the root password.  This is why password based security is not really effective if an intruder has physical access to the hardware.

If you can get access to the passwd file (and you're not using shadow passwords) there are a number of cracker utilities out there that will use an exhaustive attack on the passwords.  This takes considerable time, however.  Possibly weeks.

You could even get your machine to single user mode and change the root passwd. The best bet is what jhance has suggested. You can get crack utilities to break the passwd file.
