Reset Forgotten Root Password on VMware ESXi 5 and ESXi 4

August 10th, 2013 by Admin

Forgot your VMware ESXi Server root password? Try to log on to your ESXi server but for some reason your root password isn’t working anymore? Here we’ll show you a way to reset forgotten root password on VMware ESXi 5 and ESXi 4. But this trick is not officially supported by VMware, so do it on your own risk.

How to Reset Forgotten Root Password on VMware ESXi 5 and ESXi 4?

  1. First of all, you need to boot your ESXi server with a Linux live CD. I prefer GRML, but any live CD will do. Of course, you can also boot from a USB stick.
  2. Find the partition containing a file named “state.tgz”. For my installation, it was on a VFAT filesystem labelled “Hypervisor3”, which is accessible in GRML at “/mnt/Hypervisor3”. You might need to mount it manually with the command

    mount /mnt/Hypervisor3

  3. Unpack the “state.tgz” file somewhere. It contains exactly one file, which is another archive named “local.tgz”.

    cd /tmp
    tar xzf /mnt/Hypervisor3/state.tgz

  4. Unpack the “local.tgz”, and find an “etc” directory containing several configuration files.

    tar xzf local.tgz

  5. Edit the file etc/shadow to change the password.

    vi etc/shadow

    Probably the easiest way is to replace the line starting with “root” with the line of another user account of which you know the password. You only need to change the name at the beginning of the line (before the first colon) to “root”. You’ve then set the root password to a password you know.

    Alternatively, you can just remove the hash altogether (everything between the first and the second colon) and login to the service console as root with no password at all.

  6. Re-pack the files and move the modified state.tgz back to the VFAT partition. Probably it is a good idea to make a backup copy of the original state.tgz in case something goes wrong:

    mv /mnt/Hypervisor3/state.tgz /mnt/Hypervisor3/state.tgz.bak
    rm local.tgz
    tar czf local.tgz etc
    tar czf state.tgz local.tgz
    mv state.tgz /mnt/Hypervisor3/

  7. Reboot back into ESXi and you’re done.

How to Fix Error 0x0000005D When Booting from Windows 8 Installation Disc

August 4th, 2013 by Admin

When installing Windows 8 on a new PC or in Oracle VM Virtual Box or VMware, many users are getting the error that says “Your PC needs to restart. Please hold down the power button. Error Code: 0x0000005D.” during the booting process.

Unlike Windows Vista and 7, Windows 8 is not compatible with all models of AMD/Intel processor. To fix the 0x0000005D error, you must have processor that supports Data Execution Prevention features. It has two different names. For, Intel processor its called “Execute Disable (XD)” and for AMD processor “No Execute (NX)”. Most CPUs have support for these features, so if you receive this error, it is likely because the XD or NX feature is not enabled on your system.

How to Enable Data Execution Prevention feature?

Once you enter in BIOS, go to Advanced Options and select Processor then No Execute Memory Protection, if not, then Security > Options and Select Execute Disable. Change this to ‘Enable’ or ‘On’.

If the BIOS setting for the XD/NX support option is not available on your system, you may need to contact the manufacturer for updating the BIOS. Note that some older processors may not contain these features and will be incompatible with Windows 8. If you want to check if XD/NX is available or enabled in your system, you can download Securable which will tell you.

If your processor supports Virtualization Technology (VT) & Data Execution Prevention features, then you should see the following result in your screen:

Getting Error Code 0x0000005D during Booting Virtual Machine from Windows 8 Installation Disc?

When trying to boot a virtual machine from Windows 8 installation disc, you may also get the 0x0000005D error.

windows-8-boot-error

To fix this problem, you also need to follow the instructions above to enable Data Execution Prevention feature in the BIOS of your physical machine. Moreover, enable the “Virtualization Technology (VT)” feature in BIOS.

Here is how to enable VT option in DELL poweredge server:

Reboot your DELL poweredge server, press F12 to go to the BIOS, select “Processor Settings”, and set “Virtualization Technology” to “Enabled”.

However, from my experience, even if I have enabled both the “Data Execution Prevention” and “Virtualization Technology (VT)” features in the BIOS of host OS, I still get the 0x0000005D error while booting a VMware virtual machine from Windows 8 ISO image. Eventually I fix the error by changing the operating system version under Virtual Machine Settings of VMware Workstation.

vmware-settings

As long as you change the version to any x64 edition, the 0x0000005D error will disappear immediately.

How to Fix “Cannot Log on to Windows After Removing from Domain”

August 1st, 2013 by Admin

Problem:

After you change a computer’s membership from a domain to a workgroup and restart the computer, you cannot log on with your previous user name and password. You may also receive the following error message:

The system could not log you on. Make sure your user name and domain are correct, then type your password again. Letters in passwords must be typed using the correct case. Make sure that Caps Lock is not accidentally on.

Solution:

This problem occurs because the user name and password that you previously used are available for logon only to a domain. Your computer is no longer a member of a domain. Therefore, your logon attempt must be validated on the local computer by using the local security database. To log on to your computer, you must use the local user account existing in the Security Accounts Manager (SAM), not the domain user account.

If you do not know the local user account and password, you cannot log on to the computer. To resolve this issue, the easiest way is to use PCUnlocker Live CD to blank your local admin/user password. Here are the step-by-step instructions:

1. Download the zipped ISO image of PCUnlocker using another computer you have access to. Unzip the download file and burn the pcunlocker.iso file to a blank CD using ISO2Disc program.

2. Put the PCUnlocker Live CD into the CD drive of the locked computer that you’re trying to gain access to. Have the computer to boot from PCUnlocker Live CD.

3. After booting from the Live CD, it will start the PCUnlocker program after a while. Choose the local administrator account and then click on “Reset Password”. The program will blank the local administrator password instantly.

4. Restart the machine and remove the PCUnlocker Live CD, you can then log on to Windows with the local administrator account, without being prompted to enter a password!
