Imagine pc 1 :main server on "vm ware" Pc 2 : local server (vm ware) Pc 3 : AD/DNS server (vm ware) Pc 4 : client (vm ware) Now i have to connect pc2 to main server, i tried putting same range as on server to pc2 but it didn't ping," but i didn't change the vm option to bridge" What is the problem, should i change my network option to "Nat" to "bridge" ?
Genio total!
You saved me a valuable time, thank you.
Hello, this works on which windows os please ?
Through Win 11 -- in this video this laptop had Win 11 on it. No bitlocker or boot lock though - I haven't tried that yet.
@@JohnathanYerby Thx. Work on all windows version or only a few ?
@@PaulRoger973 all of them for as long as you can boot into the environment, this will most likely work.
good song
Hi, Yerby! I've done all above, and can ping Google's DNS, different IP addresses for both machines, and refreshed the MAC for one of them to ensure it is different; I still can't get them to ping eachother. Any idea what I may be overlooking? Both Windows-10 machines. Thank you for the video!
Just mention there is also defrag tool never dont use Defragment on SSD disk this is only for HDD. Defragment will copy all fragments to the first chips and this will shorten that SSD lifetime
Thank you!!!! I missed the part of opening 7zip and then the extraction. 😂
Thanks for the Vd. very educational and easy to follow. Thanks again. (easy to follow.)
File size 21GB?
I can't recall, but probably somewhere around there.
Medicat is big because it's not just for password resets. It comes with several, and I mean several tools.
one of my drive is protected by bitlocker is there a way to work around it?
Your video was exactly what i needed, NTPWedit worked first time. Thanks for the pointers, get quality video/editing!
Is the vmware NAT network the same as a WAN NetworkK?
NAT is like it was setup behind a networking device running NAT - that device has one IP and uses NAT to give the machines behind it a protected address. It would not be a public address, or even an address on your real Local Area Network -- however - part of what NAT does is allow traffic out to the Internet through that device (hypervisor running NAT) and route it back to the device without exposing the device directly to the public. --- so... no :)
Bro Possible To Rest or delete bitlocker password in Locked Hard Drive like D Drive E Drive from Medicat?
That data is encrypted so no.
@@edwald4056 oh thank u bro ❤️
Medicat medicat medicat meoowwwww iloveit
Please I have same product name laptop that was given to me with the password written on artached piece of paper but did not work. Please what tools do I need to download into my flash drive that woukd help me access the system?
You can get the Medicat USB here - medicatusb.com/ -- then follow the instructions to make a bootable drive. Once you do that - put the bootable drive in the PC that you are trying to recover and follow what I did in the video above. -- You will need access to another machine to make your flash drive.
hahaha... what the h is this?? he did it for what???
Awesome. Is this Windows 11?
It's running a boitable Windows PE image.
@@DrYerby Bro Possible To Rest or delete bitlocker password in Locked Hard Drive like D Drive E Drive from Medicat?
@@Prince.AlBalushi I do not believe so, not with this tool. There are some published reports of breaking bitlocker through sniffing them off of the TPM chip... I've never tried this. www.tomshardware.com/pc-components/cpus/youtuber-breaks-bitlocker-encryption-in-less-than-43-seconds-with-sub-dollar10-raspberry-pi-pico
@@DrYerby oh thank u so much dear ♥️♥️
The TPM approach requires more technical know-how than not knowing Bitlocker encrypts data. 😊 Just saying.
The NAT option did not work, does it have to be NAT in both VM's or just in one?
I do not have this setup with me now to test - but my thought is that they both need to be on the same NAT network. It would be like plugging both machines into a switch (with no VLANs or segregating traffic) - once they both have the same network they should be able to communicate.
What button are you pressing to open the software inside of jayros lockpick
Just using the arrow keys and the Enter button. You want to get to the .wim which is a Windows Imaging Format - or like booting to an OS disc.
preciate it
Doesn’t work for me, still locked and i tried all the tools for removing password, and i cant even open files while using mini windows 10 for example i want to open docx file where are all password writed it says something like unable to open no permission, how to save my data, any help or suggestion ?
Is this a local or domain password? This is less likely to work on domain passwords - but perhaps there is a local account that you can either enable, create, and set the password. Then take control of the files that you are attempting to access.
@@DrYerby yes, it is probably domain becouse it is a company laptop, I only want to access user account…
@@MaximusDecimusAnonymus I do not believe these will work for that - you can still try to address one of the local accounts -- if it is a domain account and you can get it back on the network, you can just request that the admin reset the password -- if that's not an option - you can try to still use something like Medicat - boot into a WinPE - then access the files that you're needing - copy those out
@@DrYerby Can we add a new user with admin privileges to make backup of our files?
hi doc thanks for the video can i switch to nt user in cmd?how if yes
😂 *Promo SM*
I have been using hbcd for over a decade now. great stuff when end users change their passwords on company computers that prevent me from updating their system.
Nice to know that your giving a lectures such as this one, thank you sir
Hi, I can't find the user assist folder on my laptop running Windows 10. Why?
Was it in use when acquired? You have to get it while not locked in use.
start play list of all tools uses of medicat...😍😍
So Googles find my phone with extra steps
Thanks Paji
I have downloaded the exact file but I could not find .vmx file into it. what could be an issue here ? I am using 64-bit operating system, x64-based processor, Windows 11 Pro Education Edition. thanks
If you have the ova or ovf file. You just need that. Once you have that use it like an executable. Open it with your VMware and follow the prompts. It will set up the new vm for you with the OS installed and the vmx file will be there with the configuration - which you can edit to optimize your usage of your hardware.
Thank you@@DrYerby
I was just going back through your comments and the video -- make sure that you have your explorer set to display the file extensions. It may be that it is there but you're not seeing .vmx --- Also - maybe the download or unzip was incomplete - you could re-try those as well.
Supposedly, I had an issue like that cause the VMware Workstation ask me to disable right side effect into the launched Vm file and it was opened aftermath. @@JohnathanYerby
thank you it really helped
Awesome I tried a lot of videos but finally I got here with your video, thanks a lot Dr yerby
Glad to hear that
Worst video of all time
Thanks for the info! Really useful.
You bet!
does caine 13.0 suport this tutorial?
Yes - CAINE is open source and installable. It's based on Debian and Ubuntu (LTS). It uses the MATE desktop. The process is still the same as it was with version 10.0.
Very clean video, thank you
Glad you liked it!
Thank you for the quick WinHex video. Do you plan on uploading more WinHex focused videos? Thanks!
I'm not sure... no plans to do it right now - but I will keep this in mind if I am doing something else interesting in WinHex soon.
how to create a group with different VMs in VMware Workstation 17 pro?
Shared VMs or networked VMs? --- Shared docs.vmware.com/en/VMware-Workstation-Pro/15.0/com.vmware.ws.using.doc/GUID-32D21846-E12C-40A4-A02F-E9315B0AE8FE.html --- Network together - ruclips.net/video/7qsTrNuaclI/видео.htmlsi=OtAQMD8D9vZc-93s
So what is the one where you are not connected to a host, or its own network?
Automatic Private IP Addressing (APIPA) is a feature in operating systems (such as Windows) that enables computers to automatically self-configure an IP address and subnet mask when their DHCP server isn't reachable. The IP address range for APIPA is 169.254. 0.1-169.254. 255.254, with the subnet mask of 255.255.
Unfortunately, it no longer works. There is no play button; the magic wand icon shows up instead.
is this safe (pls reply)
So outdated now. I'd skip it at this point.
oh
Do I run two virtual machine simultaneously in VMware workstation player?
If you're using Player specifically I believe it's limited to one VM. You'll want to use workstation pro or the free virtualbox will work.
Update - right now, Broadcom is giving workstation pro and Fusion away for free for personal use.
@@DrYerby Thanks for the info! :)
Hi, I cant find a user assist folder. Why?
Make sure that you are using a NTuser.dat file that was not in use when it was acquired. I have not checked this on Windows 11. It may be an issue with the version of the operating system.
Hello Prof, can I get your personal email or any form of communication channel to discuss a challenge am facing with pfsense for your help?
Hello sir! Thank you for this content. I am doing a sample project on how to create a new case in autopsy. I am using an old iPhone of mine. From what I am researching, would I need to backup my iPhone on an external hard drive as you did and then upload it into FTK imager and then upload to autopsy?
That will be slightly different. You'll need to get the iphone file in a format that autopsy can read. There is a newer ingest module - iLEAPP - it's looking for a tar file. You can extract that a couple of ways. - Or if you have access you can use a tool specifically for mobile forensics. - if not, and you want to use Autopsy anyways, just look for more information on iLEAPP.
That stupid VMX files isn t recognize by Windows!
The VMX file should be opened using your hypervisor, such as VMware Workstation Pro or Fusion for Apple. You can usually get a free 30 day trial of pro, or use VMware player. Then you can open the virtual machine.
@@DrYerby thanks, you helped me fix this issue, have a nice day , you are an awesome human being!
Thanks
Thanks your video was really helpfull
I want to get someone's opinion on physical imaging who is expert in mobiledir forensic pro can you you please guide me.
