Follow this post to install the Windows Roaming Client via Intune, Microsoft's endpoint manager. 

What you need from DNSFilter 

1. Setup a network Site to associate with the agents. Make sure to assign the appropriate Filtering Policy and Block Page to the Site
2. The Site Secret Key (SSK) from the Roaming Client Install tab
3. The 64-bit Windows Roaming Client .MSI file (download from the same agent Install tab in the dashboard)
4. Add the SSK to the .MSI file NKEY line

Intune Specifications

Add the Windows Roaming Client following Microsoft's Line of Business instructions. 

1. Add the .MSI file as the App Package file
2. Use these specs on the App Information page:
   1. Name: DNSFilter agent 64bit
   2. Description: DNS Filter Agent
   3. Publisher: DNS Filter
   4. App Install Context: Device
   5. Ignore app version: Yes
      This setting allows the roaming client to stay updated via auto-update without errors of the MSI reinstalling (due to the version not matching)
   6. Command-line arguments: NKEY = "Your Site Key"
   7. Category: Computer Management
   8. Show this as a featured app in the Company Portal: Yes

✍️ When entering in quotes for the NKEY, make sure to use straight quotes instead of smart (curly) quotes. Smart quotes will prevent the Windows Roaming Client from registering successfully.

Once the agent is added, add groups in Intune as needed.
