Windows 11 shared pc acces problem

After a Windows 11 update, shared folders on a PC may become inaccessible due to changes in network discovery, file sharing, or security settings.

See how to fix the problem

Open Gpedit.msc

Local computer policy>Computer Comfigration>Administrative Templates>Netwok>Lanman Server Worksatation> Enable insecure guest logons  If it is Not- Configured  then Change it to Enable

Local computer policy>Computer Configration>Security Setting>Local Policies>Security Options : Microsoft network client: Digitally sign communications (always)

==========================================================================

Using  Regedit

a. On the Start Menu search, type gpedit and start the Edit Group Policy app (i.e. Local Group Policy Editor). If you are using Home edition, skip to step 8.

b. In the console tree, select Computer Configuration > Windows Settings > Security Settings> Local Policies > Security Options.

c. Double-click Microsoft network client: Digitally sign communications (always).

d. Select Disabled > OK.

 

7. Disable the guest fallback protection:

a. On the Start Menu search, type gpedit and start the Edit Group Policy app (i.e. Local Group Policy Editor). If you are using Home edition, skip to step e.

b. In the console tree, select Computer Configuration > Administrative Templates> Network > Lanman Workstation.

c. Double-click Enable insecure guest logons

d. Select Enabled > OK.

If you're running Windows 11 Home edition, the guest fallback option is still enabled by default, so you're probably not reading this blog post. But if for some reason it is on, or you need to turn off SMB signing due to some third-party NAS, you will need to use PowerShell to configure your machine because there is no gpedit tool by default. To do this:

a. On the Start Menu search, type powershell then under the Windows PowerShell app, click Run as administrator. Accept the elevation prompt.

b. To disable SMB signing requirement, type:

 

Set-SmbClientConfiguration -RequireSecuritySignature $false

d. Hit enter, then hit Y to accept.

c. To disable guest fallback, type: 

 

Set-SmbClientConfiguration -EnableInsecureGuestLogons $true

e. Hit enter, then hit Y to accept.

 

At this point you will be working if Signing or Guest were your real problems. 

 

Important: we have not removed your ability to enable SMB1. All editions of Windows 11 have SMB1 disabled by default - this has been the case for over a year now and, in some editions, going back to Windows 10 - but you are free to re-enable it if you have a third-party NAS that only supports SMB1. SMB1 supports signing but your NAS may not, so the steps above for disabling signing can still apply. SMB1 always allows guest fallback and it cannot be stopped, so the guest steps are not applicable. If your third-party NAS still requires SMB1, it's likely listed here https://aka.ms/stillneedssmb1. If you find that it also doesn't support SMB signing, please let us know with the email address below. 

 

Creating a copy of a physical hard drive (HDD), including its operating system (OS), to a virtual hard drive (VHD) image

Creating a copy of a physical hard drive (HDD), including its operating system (OS), to a virtual hard drive (VHD) image involves several steps. You will essentially be performing a disk cloning process that converts the contents of your physical HDD into a virtual hard disk format. This allows you to run the OS and programs from the virtual disk in a virtual machine (VM).

Here’s how you can do it:

Requirements:

• A virtualization software (e.g., VMware, VirtualBox, Hyper-V) that supports virtual hard disk (VHD or VDI) formats.
• Disk cloning software like Clonezilla, Macrium Reflect, or Acronis True Image.
• A working physical machine with the OS you want to copy.
• Sufficient storage space for the virtual HDD image.

Steps to Create a Virtual HDD Image from a Physical HDD

1. Prepare the Tools

• Install a virtualization software such as VirtualBox, VMware Workstation, or Hyper-V.
• Install a disk cloning tool like Clonezilla (free), Macrium Reflect (free and paid), or Acronis True Image.

2. Clone the Physical HDD to an Image File

• Use your disk cloning software to create an image of the physical HDD. The image should be stored on an external drive or in a different partition (since it will likely be quite large).
• Most tools will allow you to create a disk image (e.g., .iso, .img) or clone the entire drive sector by sector.

Example with Macrium Reflect:

• Open Macrium Reflect and select the source disk (the physical HDD).
• Choose “Create an image of the partition(s)” option and select a destination where you want to save the image.
• Complete the imaging process.

3. Convert the Image to a Virtual HDD

If the cloning software creates an image file (like .img), you can convert it to a VHD or VDI format, which can be used by virtualization software.

• Using VirtualBox: You can use the VBoxManage command to convert the image into a VirtualBox-compatible virtual disk.

pgsql

Copy

VBoxManage convertfromraw /path/to/image.img /path/to/vm_disk.vdi --format VDI

• Using VMware: VMware has a tool called vCenter Converter that can convert physical disks to virtual ones.
0. Install VMware vCenter Converter.
1. Run the tool and select the option to convert a physical machine.
2. Follow the wizard to create a virtual machine and select a destination in VMware.

4. Create a Virtual Machine and Attach the Virtual HDD

Once you have the virtual hard disk (VHD/VDI), you need to create a virtual machine and attach the newly created virtual disk.

• In VirtualBox:
0. Open VirtualBox and create a new virtual machine.
1. When it asks for a hard disk, select “Use an existing virtual hard disk file” and choose the .vdi file you just created.
2. Proceed with the rest of the VM setup and boot up.
• In VMware:
0. Create a new virtual machine.
1. When it prompts for a disk, choose to use an existing disk and select the .vmdk or .vhd file.
2. Complete the setup and start the VM.

5. Adjust the Virtual Machine Settings

Depending on the hardware and OS, the VM might not boot correctly right away. You may need to make adjustments:

• Install VMware Tools or VirtualBox Guest Additions for improved compatibility with the virtual environment.
• If there are issues with drivers (e.g., storage controllers), you may need to change settings for the virtual machine's virtual hardware (e.g., IDE, SATA, etc.).
• You might also need to adjust network or display settings for better performance.

6. Boot the Virtual Machine

Once everything is set up, start the virtual machine. The system should boot from the virtual disk, and you should have access to the same OS and programs you had on the physical machine, running in a virtualized environment.

---

Additional Notes:

• Sysprep: Before cloning your physical machine, it is recommended to run Sysprep (System Preparation Tool) on Windows to generalize the OS. This removes hardware-specific information and ensures the virtual machine can adapt to virtual hardware without issues.
• For Windows: sysprep /oobe /generalize /shutdown
• Performance: Virtual machines might have lower performance compared to a physical machine, especially for graphics-intensive applications. Ensure that you allocate sufficient resources (RAM, CPU) to the VM.

Conclusion:

By using disk cloning tools and virtualization software, you can successfully create a copy of your physical HDD and boot it as a virtual machine. The key steps are cloning the physical drive to an image, converting the image to a compatible virtual disk format, and configuring the virtual machine to run from that disk.
