You need to get on the system one way or another as superuser (root). Then edit /etc/shadow exactly as MadeInGermany says to remove the hashed password field for user root.
Usually superuser access is achieved by booting from DVD (installation media) into single user:
which will not take you into the installation routine but allow you a shell to make changes.
This is easier if you are running simple UFS filesystems.
If your filesystems are ZFS then post back here and we'll tell you how to do it.

Hello All,
I have several solaris boxes running Solaris 8. When changing root passwords on them, all will simply ask for the new root password to change and of course to re-type the new password.

sulogin
sulogin(1M) System Administration Commands sulogin(1M)NAME
sulogin - access single-user mode
SYNOPSIS
sulogin
DESCRIPTION
The sulogin utility is automatically invoked by init when the system is first started. It prompts the user to type a user name and password
to enter system maintenance mode (single-user mode) or to type EOF (typically CTRL-D) for normal startup (multi-user mode). The user should
never directly invoke sulogin. The user must have the solaris.system.maintenance authorization.
The sulogin utility can prompt the user to enter the root password on a variable number of serial console devices, in addition to the tra-
ditional console device. See consadm(1M) and msglog(7D) for a description of how to configure a serial device to display the single-user
login prompt.
FILES
/etc/default/sulogin
Default value can be set for the following flag:
PASSREQ
Determines if login requires a password. Default is PASSREQ=YES.
/etc/default/login
Default value can be set for the following flag:
SLEEPTIME
If present, sets the number of seconds to wait before login failure is printed to the screen and another login attempt is allowed.
Default is 4 seconds. Minimum is 0 seconds. Maximum is 5 seconds.
Both su(1M) and login(1) are affected by the value of SLEEPTIME.
ATTRIBUTES
See attributes(5) for descriptions of the following attributes:
+-----------------------------+-----------------------------+
| ATTRIBUTE TYPE | ATTRIBUTE VALUE |

|Availability |SUNWcsr |

SEE ALSO auths(1), login(1), consadm(1M), init(1M), su(1M), attributes(5), msglog(7D)NOTES
By default, the root user has all authorizations.
Granting the solaris.system.maintenance authorization to the Console User Rights Profile may have an undesirable side effect of granting
the currently logged in user maintenance mode access. The solaris.system.maintenance authorization should be directly granted to appropri-
ate users rather than through the Console User Rights Profile.
