The question was :-

        I have received more than 100 answers. Out of all those I am posting
        two solutions.

1. Suggested by Lori Colleran (lcollera@amgen.com).

You need to executing the following steps.

1) Before you boot from CD, check out the device name of the / (root)
partition by looking at the /etc/vfstab file. Normally the / (root)
partition is /dev/dsk/c0t3d0s0.

2) Put the Solaris 2.3 CD in the CD-ROM drive.

3) Boot from CD using one of the following commands.

If your boot prompt is "ok" then

ok boot cdrom -sw

If your boot prompt is ">" then

> b cdrom -sw

4) The above command should boot to single-user and leave you at the
single-user prompt, "#".

# cd /tmp

5) # mkdir mnt

6) # cd /

7) # mount /dev/dsk/c0t3d0s0 /tmp/mnt

In the above step you would replace "c0t3d0s0" with what was found in
step # 1 as the / (root) partition.

8) # cd /tmp/mnt/etc

9) # chmod 777 passwd

10) # cd /

11) # umount /tmp/mnt

12) # halt

13) Remove the Solaris 2.3 CD from the CD-ROM drive.

14) If your boot prompt is "ok" then

ok boot -r

If your boot prompt is ">" then
> b -r

15) Login in as any user except root at the "login:" prompt.

16) % cd /etc

17) % vi passwd

Make the appropriate edits to the passwd file.

18) % su

19) Password:password

20) # chmod 644 passwd

We did this once and solved it by.
A: Booting from the CD rom. At the first suninstall window bring up another
window.
B: mount /dev/dsk/c0t3d0s0 /mnt
C: cd /mnt/etc
D: chmod +w passwd
E: vi passwd
F: reboot

==============================================================================

I hope this helps all those people who had faced this problem and had
to re-install the operating system.
