Windows Server: no integration for 3rd party "providers" in "security center"?

We're seeing Windows Defender and Palo Alto Cortex XDR fighting for resources on a number of our Windows Server instances...





...and noticed that "Cortex XDR" is not listed as a "provider" in Windows Security Center despite having been installed.





clicking on "Manage providers" results in the following page:





("the page you are trying to access has no supported features and is not available")

Palo Alto docs say this:

The Cortex XDR agent registers with the Windows Security Center as an official Antivirus (AV) software product. As a result, Windows shuts down Microsoft Defender on the endpoint automatically, except for endpoints that are running Windows Server versions. To avoid performance issues, Palo Alto Networks recommends that you disable or remove Windows Defender from endpoints that are running Windows Server versions and where the Cortex XDR agent is installed.

Would anyone know

1. Why I can't access "providers" under "security providers" in Windows Server 2019?
   
2. Why doesn't (or can't) Palo Alto shut down or disable Windows Defender on Windows Server versions after installing Cortex XDR?
   
3. What is the best way to automate the process of disabling Windows Defender on Windows Server instances where Cortex XDR is actively protecting the system?
   

Thanks!

P.S. Non-server Windows editions are unaffected: managing security providers is an option in "security center", for Windows Defender and Cortex XDR, with Windows Defender disabled ("passive") after Cortex XDR installation.

 

Hijack iCloud integration to access to CalDav server.

I have just got a Windows Phone (Lumia 630, WP8.1).

I need to access a 3rd party CalDav server, but it seems that there is no generic CalDav support.

However, a bit of searching suggests that setting up iCloud integration and then changing the address of the CalDav server to point to the one that you want should work.

So I...

• Set up iCloud integration.
• Checked that calendar integration worked both ways.
• Changed the CalDav server address to point to 3rd party CalDav server.

This half works:

• I can create an event on the phone, and it get's written successfully to the calendar on the server.
• But I can't see any events (including the one I just created) from the phone.

Has anyone got this approach to work successfully, or have any suggestions as to what to do to get it all working?

 

Windows Server: no integration for 3rd party "providers" in "security center"?

I'm sure you'll eventually get a clear answer at the Q&A Forums, but the thread where I found the same excerpt you did regarding why Windows Defender Antivirus on servers operates differently than the commercial Windows Defender for Endpoint Plans seems to describe the reason in the following section quite clearly.

Microsoft Defender Antivirus compatibility with other security products | Microsoft Learn

That same document describes how to uninstall Microsoft Defender Antivirus (or Windows Defender Antivirus for Windows 2016) using a PowerShell cmdlet in the dialog box immediately preceding that section referenced above.

This sems confusing only because of the similar naming, while that document details the specific differences for the standalone Defender and Endpoint versions, as well as how they operate differently relating to passive mode, which is what you're trying to manage.
