I have a windows deployment server on prem.
I have 20 windows servers for which I installed the Universal Forwarder and pointed it to the deployment server over port 8089.
Where within the deployment server can I confirm that the 20 windows servers are all reporting in?
On the Deployment server instance go to: Settings > Forwarder Management.
In the Forwarder Management screen go to the Clients tab to verify all the clients that are phoning home to the Deployment Server and the last time that it phoned home.
