  My Powershell skills are still very basic, but in progress, however .

  Everyone would be able to explain why it crashes and how can I solve it?

  Thanks in advance

  Very strange but this script works now and I wouldn't change a thing!

  I was close PowerGui Script Editor, and then open it again when I received your second answer. Indeed, very strange, but I guess I got a lot to learn about Powershell yet!

  Thanks for your quick responses so!

• change root password

  If I change the root password on my host esx 4.1, do I need to do anything in Virtual Center because he then recognizes this change?

  No, vCenter Server creates its own user (vpxuser) on the ESXi hosts to access when the host is connected to vCenter. You may need to verify that the root account is not used for other applications.

• Consequences of change root password

  We lost our root password for our two esx3.5 boxes and I have some questions that I hope someone can help me with, as I am a fairly new admin of VMware.

  I have instructions on how to change the root password (http://www.petri.co.il/vmware-esx-server-root-password-reset-recovery-lost.htm) which look good, but I'm not sure on a number of things:

  (1) what else will be affected if the root password is changed? We have vcentre, vmotion, vcb and possibly other utilities that I I know not. If I change the root password, one of these (or other applications common/standard) will affect and need to be changed to reflect the new password? In my view, it is not recommended to use root for something like this, but I don't know if it happens.

  (2) we have two hosts in the cluster. Do I have reason to assume that I can change the root on one host at a time or make different from eachother? Not that I'm likely to make them different, but my plan is everything to a single host, reset the password on the void and see how it goes. If everything continues to work I then move everything to this host and reset the password on the second host, term, threaten things back where they should be. I am likely to face a problem that do it this way?

  Any advice or comments appreciated.

  Welcome to the forum.

  As written there is no consequence.

  This because the vCenter Server using the root connection only when guests first connects.

  Then he will add a new user (vpxa) and uses this user.

• Question - change the stupid root passwords

  
  I use the same passwords for root for too long to my vm hosts and need to change to improve safety.    The hosts are all added in Vcenter and clustered.    If I change the root password of the individial hosts, is what it's going to break the bond of vcenter?    I know that you type in passwords for root when connecting host to vcenter, but then it installs vpxuser, then I guess it should not occupy root changes after that.   I just wanted to confirm with someone who did this recently.

  (5.0 and 5.1 with Vcenter 5.1 ESXi)

  Hello

  No, the root passwords change does not affect the vCenter.  No link will be broken. It authenticates just the first time that you add the vCenter Server inventory.

  You even change passwords on multiple hosts in a row only to avoid the hassle of Power-Cli scripts.

  Thank you

• Change the root password interactively

  Hello
  I want to change the password of root interactively using a configuration script, where I change many more parameters, without specifying the new root password in the configuration script.
  I would like the script to give me a chance to type the password to myself.
  Something like when you started a new cmd session in a .bat script using the cmd /c
  Thank you

  Take a look at this script and see if the way they work for you: http://communities.vmware.com/thread/412623

• Change the root password

  Hello!

  I would like to change the password to root for our ESX 4.0 servers. Problems or advice?

  Unless you actually use the root connection in some application or script, and the saved password here - no problems.

• Try to set / change the password BIOS admin via the script WMI on ThinkStation D20

  Hello Lenovo Community!

  Start using the WMI Lenovo_SetBiosSetting class on a D20 system.

  If I understand the documentation that there is a limitation on the BIOS password in the past, but I updated to the latest BIOS Rev who support States was added for this feature.

  I use a script that changes the supervisor on computers password successfully thinkpad, but when even to run the script from command line on the D20 system it returns "SUCCESS" however to change the password did not effect!

  I'm using the right parameters are the standard of lenovo

  ' pap, oldpass newpass, ascii, we.

  I thought maybe "pap" is not the correct setting for password Admin on the D20, however the WMI available, posted 2010 guide, does not show otherwise.

  Someone at - it an example script that they can display successfully change the password on a D20 system?

  Please and thx!

  Did you run the SaveSetting script after changing the password?

  You can get the SaveSetting script from the sample scripts D20 located at the following link:

  http://support.Lenovo.com/en_US/downloads/detail.page?docid=UM002033

  You can use the script SetAdminPassword from the library of scripts of series E, then a follow-up that with something like what follows before restarting:

  "cscript SaveSetting.vbs" originalpwd, ascii, we.

  Replace 'originalpwd' with all what your existing password was at the time wherever you booted the system.

• Can I change the root password in VoP Server Explorer?

  Hello

  I was encouraged to see VoP Server Explorer, but my network does not have any system to have a default root password. Can I change the root user password?

  Thank you!

  Altogether.  Just connect to the console as root and type 'passwd' to change the root password.  Be sure to keep track of what you set, because there is little recourse except in single-user mode if it goes astray.

• What should I do on vCenter vSphere Web Client after you change the host root password?

  Hello

  When we implemented vCenter our Organization, we used a regular password to the account 'root' on each ESXi host.

  So, I installed vCenter and added the hosts on it to manage.

  When I added them, they've asked for the root password power connect.

  Ok. Everything was fine.

  Now, we want to change the password to root for each ESXi host.

  My question is: what should I do to make sure that vCenter will always be able to connect to the ESXi hosts, because the account used to connect the first time change his password?

  My question is: what should I do to make sure that vCenter will always be able to connect to the ESXi hosts, because the account used to connect the first time change his password?

  Nothing, after the host is added to vCenter, a user named vpxuser is created automatically on the ESXi host and vCenter uses this user to connect and manage the host.

• Help, I changed the password of root ESXi via powerCli, now I can not connect with the web client or the console.

  Help, I've changed the root ESXi via powerCli password, now I can not connect with the web client or the console, but I can still connect to powerCli. The command I used was;

  SE connect-VIServer esxihostname-user root - password newpasswd

  This production network btw, I have connected to each host and run the above command, these ESXi hosts are not on a domain

  y at - it something I have left out. I really appreciate any assistance that you people can provide.

  Thank you, Joe

  It is probably a longshot, but a lot of things in the land of windows is not sensitive to capital letters as Unix is.  I wonder if your new password you put through powerCLI mixed uppercase in it and if the capitalization was abandoned by command windows powerCLI Analyzer, or he interpreted as all capitals or something.   If you can still get through the powerCLI you could try to reset the password again to something simple without capitalization mixed case and if your password on ESXi strategy requires a special character, try something different than a "$", like a "_" (I find that a '_' is less likely than some other special characters (, as a '-' or a ' / ' to cause problems with analyzers.).

  Edit:

  Another thing, you can try before playing with the password once again, is to create a different username ESXi using powerCLI and see if the password ends up what you think, it should be, and if you can get with the client vsphere using it.  In this way, you can find out if there are some problems with certain characters or Cap through command powerCLI Analyzer without losing your remaining root by powerCLI access.  After some tests, you can understand what went wrong with your initial password change and may be able to fix it with less risk of losing access.  I also assume that you can not create a new username on ESXi who is able to change the root password no matter what authority give you it, otherwise, you could create a new username with PowerCLI, then connect to the client vsphere with it and change the password to root from there.

• Change of the Esx server root password.

  Hello friends,

  I have a small queries if you change the root on Esx server password there will be an impact on virtual infrastructure if it so please explain what effect might be on OS comments and please let me know how to change the password if it is not an impact. the Esx version is 3.5...

  Thank you

  Unless you use any application that connects to the host by using the credentials of the root, there should be no problem with changing the root password. Virtual Center uses its own (vpxuser) user to access the host.

  You can use the Set-VMHostAccount cmdlet to change the password of an ESX/ESXi server. Remember that you must connect directly to the host to do.
