Hi, I am testing the Window Admin center with a Old Dell Sever T620

Got window server 2016 installed on the server

- already installed Window Admin Center and added the extensions (Dell EMC OpenManage Integration), but when click on it, it got error message "Unable to communicate to target node host.allit.net . The possible reasons for failure are: 1. Target node is currently being rebooted, or is powered-off. 2. Firewall is blocking communication through SMB port 445."

Firewall is turn off on the server and also i have installed on the same server.

Am I missing something? or the system is not supported?

I couldn't a lot of resources on this...

Thanks!
