I ran across this scenario and found a solution using the unique setup of EC2 on another site: http://www.smattie.com/2012/01/23/video-remotely-reset-windows-password-via-ec2-config-service/ The video is long, so to summarize the steps: Create a new scratch EC2 instance running 2003 server, and log into it. Shut down your lost instance (the one you can't ...

It sounds to me like you're giving user support by logging on with their accounts - knowing their passwords? As you said, that's a very bad idea for many reasons. I know some oldschool users tend to like that, they just shrug their shoulders and ask you to fix it remotely and give you their password. But just say no. No one should know their password but ...

Booting in single user mode won't work for Debian and Ubuntu because you still have to enter the root password for maintenance mode. Reboot your computer to get to the grub boot screen, press e to edit one of your Grub boot configurations and edit the line starting with kernel. Append init=/bin/sh and boot the modified configuration by pressing b. When you ...

If you access it locally you can specify a new password. On Linux this would be done via ipmitool. Something like this should work: ipmitool -I open lan set 1 password NEWPASSWORD If you don't know which channel is your ethernet interface, just page through them one at at time, like so: # ipmitool -I open channel info 1 Channel 0x1 info: Channel ...

What you're doing is a really, really bad idea. If you don't want users to have to manage passwords, you can invest in a challenge/response token system for AD that will cost you minimal money.

I would not be so certain that my DC is safe. If I was an attacker or a pen-tester, I'm not going after your DC first, anyway. I'm going after your workstations and servers. Basic attack vector: Discover weak username/password either domain or some service (say sa account on SQL Server) or vulnerability I can exploit that lets me get admin rights (patch ...

I just had to deal with this same issue yesterday, I was not able to log into my SuperMicro IPMI web interface because I had not used it frequently and forgot the password. The command in Insyte's answer did not work for me but it was close. This command worked to reset the ADMIN account's password: ipmitool -I open user set password 2 ADMIN The number 2 ...

In a different session, login as root and reset your user password. sudo passwd ec2-user

For ESXi, the only supported method to change the password is to reinstall. Reinstalling the ESXi host is the only supported way to reset a password on ESXi. Any other method may lead to a host failure or an unsupported configuration due to the complex nature of the ESXi architecture. ESXi does not have a service console and as such traditional Linux ...

What I'm seeing (http://en.wikipedia.org/wiki/RAR) says that RAR3-format files use AES for the encryption algorithm. It's unclear to me on first glance if the RAR3 file format is published or if there are open source implementations of the decryption / uncompression algorithm. If the format isn't published / or there aren't free implementations of the ...

Oh, it's passwd username Sorry for asking and answering my own question. :S

If you just want to get the data off, pull the hard disk drive out and plug it into another Windows machine. If you actually want to logon and use the machine again, reset the Administrator password (which doesn't require pulling out the hard drive, and may end up being easier). As long as he wasn't using encrypting filesystem (EFS), just download the ISO ...

You can't recover the passwords as they are stored in an encrypted format but you can reset them if you have access to the mysql program with suitable privileges. Get a list of the users that mysql knows about like this mysql -u root -p enter your root password mysql select user,host from mysql.user; +------------------+-------------+ | User ...

There are methods to reset an ESXi host's root password, provided you have physical or out-of-band access to the server. I've done this with Host Profiles by reapplying the profile gleaned from another host to the affected server. But you likely don't have the licensing to support this. I've also have to use the boot CD/Live CD approach (also here), which ...

There is nothing built-in to Active Directory to allow self-serve password resets. The only Open Source utility in this vein that I am aware of is pwm. Of course, as I'm sure you already know, this isn't a technology problem, this is a personnel problem. What you need is management support behind an initiative to encourage employees to take responsibility ...

I will assume you are using Grub for you boot loader: Boot your system Select your kernel Press e Select the line that begins with kernel Append the letter S to the end of the line Press Enter then b Boot into your single user mode.You should be greeted with the root prompt #. From here: type the command passwd and reset the root password Reboot. And ...

Well, first off: sounds like your client needs to get the lawyers involved. On the technical side of things: Windows domain controllers do not have local users after being made into domain controllers. So, there's no way to log in as a local user whatsoever, with one exception: Directory Services Restore Mode. If you press F8 during boot (right as Windows ...

I'll start by expressing my agreement with other posters who are cautioning you that you may be causing more harm than good tinkering with low level stuff like this outside your area of expertise. You can really mess things up if you're not careful and change a server that's working into a smoking pile of wreckage. Proceed only with caution. Your offline ...

Actually, just a few hours ago I tried exactly that trick - on a Windows 2008 (Core) domain controller. It worked perfectly. Did you use the script linked at the bottom of that guide? Exactly what does "not having much luck" mean?

To be honest, I don't think your reasoning for wanting to do this is valid. As an admin I get a major dose of the heebeejeebees from the thought of knowing a user's password. It's their personal territory, and you're asking them to place a HUGE level of trust in you. Even aside from that, if there's ever a confidential data leak, you will be instantly ...

Accountability, Logging and Tracking. We have been struggling with management over this for a few years. The CEO and President refused to change their password for years, and every IT guy that had come and gone in 7+ years knew their passwords. Even if you "Trust" everyone, it is very unsafe for multiple people who are no longer employees to have access ...

Yes there is you have to hold down the command and s key while booting to enter single user mode: then you can do the following (checking filesystem, mounting it, starting services and changing root password): # /sbin/fsck -y" # /sbin/mount -wu / # /sbin/SystemStarter # passwd root Reboot and you're done. EDIT: there's some additional informations here ...

Refer the client to someone who actually knows the technology that they need help with? If were an electrician, and had a client that needed a plumber, I wouldn't be buying pipe wrenches and Time-Life DIY books on my way to their site. Not to sound harsh, but from the way you phrased the question (calling it a PDC, not knowing that a DC no longer has local ...

AD passwords (just like Windows ones) are stored using non-reversible encryption, so the standard answer is a definite "NO". There is a GPO settings that will tell AD (or any Windows system) to store passwords using reversible encryption, but there is no built-in tool to decrypt them (although there is some documentation floating around on how to do that). ...

How did you "modify /etc/shadow"? You should be able to copy a user's password hash from /etc/shadow from one a system on which you know the password "works" to this server's /etc/shadow and have it Just Work (TM). Oh, and don't edit /etc/shadow directly. Instead, use vipw -s. That will help prevent you from saving the file with formatting errors.

Apple has a knowledge base article on Changing or resetting an account password. http://support.apple.com/kb/HT1274

You are unlikely to find another method other than brute force or factory reset. Router manufacturers simply don't provide other mechanisms for recovering lost passwords. Reset, reconfigure, and move on. Your time spent messing around with trying to recover the password would be better spent just reconfiguring the router.

You dont have do disconnect the client from the domain first. Log on with your domain admin-user, and bring up computer management (Right-click "My computer"-->"Manage") In Computer Management, go to "Local Users and Groups"-->Users. Right-click the administrator and choose "Set Password". Also, make sure the account is enabled if you want to use it (In ...

Uninstalling the utility worked. On re-installation, the utility creates a new user database and prompts for the administrator password.

Use a boot cd! - mount your root partition to /mnt/root/ - change /etc/shadow to root::[and so on] - OR type: "chroot /mnt/root passwd" - reboot, login with empty password or the new one you specified
