Sysinternals - Adexplorer: get the currently logged in users und computers

In our small office we have a MS 2019 Server with Active Directory AD and DC, and Win 10 / 11 PCs as clients.

I can log in to my client as "user" and via my PC and Remote Desktop to the Server as "Admin".

I only(?) want to know:

• which user is logged in to my domain just at this moment
• which client / PC is logged in just now
• (which client is logged in on which computer just now)

Can this be done with ADExplorer?

If yes - Can I start ADExplorer on my client PC or on the server?

May I use my standard user log-in or do I need the domain-admin-login?

Thanks in advance for any advice!
