Create pfx file from certificate and private key

In order to create a pfx file we will need the certificate (crt file) and the private key file.
We need to download and install OpenSSL for windows https://slproweb.com/products/Win32OpenSSL.html.

The first step is to give the same filename to both files (crt and private key) and give the extension .key to the private key file.
So assuming we have the 2 files certificate.crt and certificate.key we have to open OpenSSL and execute the following command:

openssl pkcs12 -export -out newcertificate.pfx -inkey certificate.key -in certificate.crt

We will be asked for a password for the pfx file and we are done.

Move share folder from one drive to another retaining share and security permissions

We will use the robocopy command in order to copy the folder and retain all the security permissions

robocopy "D:\Data\FolderName" "G:\Data4\FolderName" /MIR /SEC /ZB /V /r:1 /w:2 /nfl /ndl

In order to move the share permissions we have to open the following registry key,locate the share and change the path:
HKLM\SYSTEM\CurrentControlSet\Services\LanmanServer\Shares
Restart the Server service and we are done.
