After a few moments, I received three responses. After almost
a day, I received over 45 responses. Wow, this mailing list is
really great.

Thank you very much for all your help.

My system is a SUN UltraSparc with Solaris 2.5 and CDE on it.
I forget to include this information when I first posted because
I was so panic at that time. Once again, thank you very much for
all your responses.

Allow me to summarize.

  a. On the keyboard, press <stop> <A> keys; this will cause the
      boot prompt to appear. I was lucky as I didn't put a password
      on the boot prom.
  b. From the cdrom drive, boot the Solaris 2.5 Installation CD by
      issuing the command 'boot cdrom' (less the single quotes).
  c. As soon as OpenWindows started, open a Command Tool window.
      Mount the root (/) partition containing the /etc directory.
    NOTE: Since I press <stop> <A> from a running system, I had to
      execute fsck on the disk slice /dev/dsk/c0t3d0s0.
  d. Edit the /etc/shadow file and remove the root password.
  f. Reboot and problem is solved.

Great Thanks to the following persons who responded:
