Can I change the administrator password on Snow Leopard using Tiger discs

Hi, I had a fault with my mac and the o/s had to be reinstalled. The shop put Snow Leopard on my mac and I changed the password which I later forgot. My mac instructed me to input the install discs etc but I only have my original Tiger Install discs. I rang the shop but they say they are not allowed to change the password but that I can do it with my old discs.
I tried to reset it but it wouldn't work and on only the first occasion when I restarted with the disc and by pressing C on reboot etc did it launch into the 'select language' etc. Now every time I try, it just starts normally.
Is there any way I can change the administrator password on Snow Leopard using my Tiger discs? thanks

Why didn't the "shop" give you the Snow Leopard system discs? You need those to troubleshoot. Especially if you need to use Apple's Hardware Test. Strange.

Changing Domain Administrator Password : How can I find out what all servers / services are currently using this?

Good morning all,
I took over as IT director for the school district in my town about 2 years ago, and we've had some techs come and go, all of which have had the domain administrator password (not my call, but my fault for not changing it by now). I am about to change
it, but before doing so I want to know how I can make sure what all this will break so I can quickly change the cached/saved password on whatever supporting services use this user/pass.
Can anyone help here?
Thank you!

Hello,
In my point of view if I were in this situation I would Change the domain administrator password. By
Resetting the domain administrators all the services which use domain administrator as their logon user, will lose their functionality. I had this experience and I did change the domain administrator password with no problem. However do not
forget to have a account lockout tool or script for locating the place where the account was locked out.
But to keep it short most of the time. lockout problems are arise from mapped drives, credential manager and saved RDP sessions and etc.
Regards.

How do I change my administrator password

After taking my MacBook in for additional hard drive, my administrator password wouldn't work. I called them back and they took no responsibility for it except to tell me to use the discs that came with it to reset it. Can someone help me please? I don't know what I'm doing. I don't want to reinstall everything, just reset my password. Btw, I can't remember my old one to reset without discs. Thanks!

Put your install DVD into the optical drive and reboot. As soon as you hear the boot chime, hold down the "c" key on your keyboard (or the Option key until the Install Disk shows up). That will force your MacBook to boot from the install DVD in the optical drive.
When it does start up,you'll see a panel asking you to choose your language. Just press the Return key on your keyboard once. It will then present you with an Installation window. Completely ignore this window and click on Utilities in the top menu and scroll down to Reset Password.

How do I change the administrative password on my computer since I have bought it from someone else?

I bought this macbook from someone else and he cannot remember the password for the administrative account that im currently on. I cant do anything technical with the computer since I do not have this password. What do i do?

Then you'll need to buy an install disk. I called Apple Customer Support (1- (800) 767-2775) to check on how much they charge for the gray restore disks that originally came with the MacBook and was quoted $16 dollars per disk plus S & H. Which would be $32 plus shipping for the two disks. Just give them the serial number of your MacBook and they'll know which ones you need. With the original disks you also get the iLife that was current when your MacBook was bought included on the #2 disk.
The 10.6 Snow Leopard DVD is in the Apple online store. You can get it for $19.99. You will need to be running 10.6.8 to access the App Store to order Lion or Mountain Lion. http://store.apple.com/us/product/MC573/mac-os-x-106-snow-leopard
With the Snow Leopard disk you have to buy iLife separately for the latest iLife '11. You can get the iLife ’11 DVD which will run on 10.6 or above on eBay fairly cheap. http://www.ebay.com/sch/i.html?_odkw=apple+ilife+11&LH_Auction=1&LH_BIN=1&_sop=1 2&_osacat=0&_from=R40&_trkparms=72%253A1234%257C66%253A2%257C65%253A12%257C39%25 3A1&LH_PrefLoc=1&_sc=1&_trksid=p2045573.m570.l2632.R2&_nkw=apple+ilife+11&_sacat =18793

Can't connect after changing BI Publisher Administrator password

I have a single machine instance of OBIEE 10.1.3 on Windows. All elements have been working fine and I have been able to successfully sign on to:
1) BI Publisher
2) Dashboards/Answers
3) BI Administrator
However, today I decided to change my 'Administrator' password in BI Publisher for good order's sake. And now after making that change I get an error reading:
{color:#0000ff}*'The server can not be used due to a configuration error, please contact the administrator. If you are the administrator, please consult BI Publisher user guide for proper configuration'*{color}
With 'error detail' reading: oracle.apps.xdo.security.ValidateException
Using the old BI Publisher password also returns an error (invalid user/password). I also stopped and started OC4J service all Oracle BI products. My BI Administrator signon still works fine.
I've read several posts about failed connections like this and ran across one that implied that characters in the new password such as *, #, $ will create problems. Unfortunately my new password does contain some of these characters {:>0 and I suspect this may be the issue My question: What is the least complicated way to back out of this situation and simply restore my sign on? I'm totally focused on data architecture and reports on this single user system right now. Thanks

Madan,
Thanks for your help.
The password in xmlp-server-config.xml is encrypted. It looks (similar) to this:
<property name="BI_SERVER_SECURITY_ADMIN_PASSWORD_ENC" value="C14CD2495C033BB8E816E10BCDC25372" />
<property name="BI_SERVER_SECURITY_ADMIN_USERNAME" value="Administrator" />
I tried changing the encrypted password to my password but got a java sign on error.
I then modified the last block in CredentialStore.xml and restarted the BI Server and OC4J but I still get the 'oracle.apps.xdo.Security.ValidateException' error when signing on to BI Publisher. Here's the entry with the (dummy) password which
I tried with the first change above and without the first change above.

Change Administrative Password W/O Instaff Disc?

How do I change an administrative password if I do not have the Mac OS X Install disc? Thank you!

Thomas,
Not sure about changing the administrative password, but have you tried setting a master password through system prefs? Here's part of the help file...
+The master password is a computer-wide password set up by an administrator as a safeguard in case the administrator forgets his or her login password. The master password is usually used in conjunction with FileVault, a way of encrypting a user's home folder so it can't be seen by anyone but that user. If a FileVault user forgets his or her login password, even an administrator can't log in to the user's account with an administrator password. Only the master password can override a FileVault user's password.+
It sounds like if you lose the master password, you lose data..so use caution

Bought eMac with 10.4.3 but no OS disks - need administrator password

Just bought an eMac (1.25 GHz) with system 10.4.3 installed from the local Goodwill computer store. Boots and runs fine. However, to load some CDs and run DVDs, it requires the administrator password, which I don't know. The administrator is listed as "Owner Owner," and no OS disks or documentation were included.
How do I reset the administrator password if I don't know the original password and I don't have the OS CDs?

I've never used any of these, but one or more may work for you.
Here's the instructions if you have the discs.
*Mac OS X: Changing or resetting an account password*

Changing your administrator password
http://docs.info.apple.com/article.html?path=Mac/10.4/en/mh655.html
Here's one method to reset the password without the install disc:
1. boot computer and hold the "apple" key and the "s" key.
2. wait for terminal show
3. release keys
4. type without the quotes: "/sbin/mount -uaw"
5. press enter
6. type without the quotes: "rm /var/db/.applesetupdone
7. press enter
8. type without the quotes: "reboot"
9. press enter
This will let you create a new admin account when you reboot your computer.
Also, without the discs, look at Mac OS X Tip - No Password, No Root, No CD? No Problem.

Here is a way to get around not knowing the admin password on Macs.
To reset your OS X password without an OS X CD you need to enter terminal and create a new admin account:
1. Reboot
2. Hold apple + s down after you hear the chime.
3. When you get text prompt enter in these terminal commands to create a brand new admin account (hitting return after each line):
* mount -uw /
* rm /var/db/.AppleSetupDone
* shutdown -h now
4. After rebooting you should have a brand new admin account. When you login as the new admin you can simply delete the old one and you’re good to go again!

Step 1: Log in your Windows Server 2008 R2 computer through the administrator account.
Step 2: Click on “Start” on the lower left corner of your screen, and hit “Control Panel”, and then doubt-click on "User Account".
