How to change your Administration Server password when you're locked out
The Netscape server products are all managed by a single administration
server, which gives you a web forms-based interface you can use to
configure them, start/stop them, check their logs, and so forth.
<P>
There are three levels of protection that keep the general public from
being able to get into your administration server and mess up the
configuration of any Netscape servers you have installed:
<P>
<OL>
<LI> <B>Obscurity:</B> Your administration server can run on any port you'd
like (usually something between 81 and 30,000), so if an attacker
doesn't know what port to find your admin server on, he can't get
into it.<P>
<LI> <B>Host restrictions:</B> You can tell your admin server to only allow
connections from specific hosts, and to reject all other hosts.
<P>
<LI> <B>Password protection:</B> Even if a user connects to your admin server
from a valid host, he won't be allowed to get into even the first
page unless he presents a valid username and password.
</OL>
<P>
If you, the legitimate administrator of your web server, are unable to
access the administration server (if you forgot your password or the
admin port number or if you accidentally locked your own site out),
then here is how to get past each of these levels of protection:
<P>
<OL>
<LI> If you don't remember what port your administration server is
running on, just look in your "ns-admin.conf" file, which is in
the "admserv" directory under your Netscape server directory.
(For 1.x web servers on Windows NT, run "regedt32" and go to the
"HKEY_LOCAL_MACHINE\SOFTWARE\Netscape\Administration" section).
You will see a "Port" entry there that specifies what port your
admin server is on. You can change this value if you want your
admin server to run on a different port, but make sure you restart
the admin server after you change the value.
<P>
<LI> If your admin server is complaining "Unauthorized host" when you
try to connect to it, then you can open it up to all sites by
going into the "ns-admin.conf" file or the "Administration"
section of your NT registry, as described above, and deleting the
lines for "Hosts" and "Addresses" (either one of those might not
be present) then restarting your admin server (on Unix run
"stop-admin" then "start-admin"; on NT go into the Services
control panel and stop/start the "Netscape Administration" or
"Netscape Admin Server" service). You will then be able to get
back into the admin server, where you can then try new settings
for your host and address restrictions if you wish.
<P>
<LI> If you have forgotten the password to your admin server and now
you can't log into your admin pages, all is not lost! Go into
your "ns-home" directory, and into the "admserv" directory under
that. You should find an "admpw" text file containing a simgle
line of text, something like this:
admin:lnOVeixulqkmU
The first part of that line is the name of your admin account
(usually just "admin"), and the second part is your admin
password, encrypted. Edit this file to remove the encrypted
password so that your file looks like this:
admin:
Then shut down your admin server, bring it back up again, and log
into your admin server but don't give any password. It should let
you in, at which point you can then go to the appropriate
configuration page to set a new admin password, and then you're
back in business.
</OL><P>
Note that because it is so easy to change the admin password this
way, it's good to periodically make certain that your admin
password file and your web server's configuration files are not
left world-writable, and that only trusted people have access to
them. (By default they're not world-writable, but it's good to
make sure of this from time to time.)

Answer 1

If you mean that yu forgo the password for yur encrypted backup then you can only:
Warning: If you encrypt an iPhone backup in iTunes and then forget your password, you will not be able to restore from backup and your data will be unrecoverable. If you forget the password, you can continue to back up and use the device, however you will not be able to restore the encrypted backup to any device without the password. You do not need to enter the password for your backup each time you back up or sync.
If you cannot remember the password and want to start again, you must perform a full software restore and when iTunes prompts you to select the backup from which to restore, choose set up as a new device.
