Reset local admin password via recovery cmd

183 Views
Last Modified: 2018-11-10
Hello,

I am trying to reset the local admin password for Windows Server 2K16. The only account that has access to the desktop is a basic user account so I am unable to make any changes in the GUI (lusrmgr.msc). I tried to boot to the windows recovery prompt but I can not seem to find the drive with the local os installed. Below are the following drives that I can see in recovery cmd:

A:
D:
X:

How can I get C, or the hdd with the actual os to show? I do have a \windows\system32 folder in X but there is no utilman.exe file. This is a VMWare box if that helps

Thanks in advance!

Hello,

1. No. it does not work. D spins up as the dvd drive. There is no windows directory at all there. I do also have a X drive and it has windows\system32 folder but no utilman.exe.

2. Yes. That was my old basic account. I spoke with support and they advised me to just re create the question on my upgraded account.

Sorry for the confusion and thanks for the response.

maybe C: is just Offline, not assigned a drive letter.

I would BOOT from https://www.hirensbootcd.org/

and try again..

Andrew,

That may be my final recourse but I would have to turn that, or any third party tool, over to our security department for review and that could take days or weeks. I just do not understand why so many people have been able to run this successfully and I simply do not have that option.

It could be that additional drivers are required to be loaded, for the storage controller!

no storage controller driver, no disk!

Do you have access to the VM settings ?

Tried booting of the DVD ?

Agree try a controller driver before we continue with other steps.

I do have access to the VMWare mgmt console but I am unsure how to add it from there. I use VSphere 6.5

Any pointers please?

I've just booted a VMware virtual machine from the Windows 2016 DVD, and selected Repair, and selected a Command Prompt.

Installation was located on E:\

and in E:\Windows\System32 was the file utilman.exe.

This is using the standard Windows 2016 template for the OS. e.g. LSI Logic SAS controller.

If yours is different you may need to add a driver, unless additional security or policies have been applied.

I do use the web console

Respectfully, I do not see how to add the driver(s) preboot. Is the method to do so in one of the "parts" at the bottom of the page?

I have tried to run the cmds and I have attached the screenshot from trying to load dev manager. No luck,

In regards to "https://kb.vmware.com/s/article/1013975". I cant change the owner of the disk.sys and pci.sys since the only account that I can login with is a standard account.
