How to join a Windows 10 computer to your Azure Active Directory

Introduction

Some of the benefits of having your Windows 10 devices in your Azure AD is that your users can join the computer to your Azure AD without any extra administrator privileges, assuming you have configured this in your Azure AD. They can also login to the computer without the need of being connected to a specific company network the first time, as long as they have internet connection. You can also manage your Windows 10 devices wherever it may be in the world.



HOW-TO IMPORT DHCP-LEASES TO WINDOWS SERVER FROM PALO ALTO

In some cases you will come across DHCP-scopes that are configured on the edge-device or similar and wanting to move it to your dedicated Windows Server instead.
Below is an example where you can export DHCP-leases from your Palo Alto Networks device and add them to your dedicated Windows Server.

In this example I will be using Putty.

Step 1.
Start Putty and connect to your Palo Alto Networks firewall. Then go to the Putty Reconfiguration page, Session > Logging and select ”All Session output”.
Choose your filename and where to save it. Select Apply.

Step 2.
Log in to your Palo Alto Networks firewall and issue one of the below commands. Choose the second one if you need to specify an interface. For example if you have several DHCP-scopes configured on your firewall.

Close your session when the output has been printed.

Step 3.
Inactivate the DHCP-scope on your Palo Alto Netoworks firewall so there are no new leases being added.

Step 4.

Open the file where the output has been pasted and remove any unnecessary information.

Import the values to Excel and it should look something like this: (We are only importing IP, MAC and Hostname in this example)

Step 5.
Now we need to add the information to the command that we will be using in Powershell on the new DHCP-server.

Go to a new column on the same sheet and add the below:

This will get the information for the IP on column A and row 2, MAC-adress on column B and row 2 and the Hostname on column C and row 2.

Go the new cell and hover to the right corner. Drag down to fill in the rest of the rows.

Step 6.
If you have not already created the new DHCP-scope this is the time to do it.

Step 7.
Start Powershell on your DHCP-server and paste the below commands.

Step 8.
Activate the new scope and remember to configure DHCP-relay on your Palo Alto Networks firewall if needed.
