Testing on 3 systems, all are windows 11. 2 of them scan and find each other fine, but the 3rd can not scan to find either of the other two, and can not be found in a scan.
I tried Hostname and IP. I tried disabling the firewall on both machines.
This system is locked down by corporate, but I have a local Admin account to bypass anything I need to.
I tried to reinstall as Admin, still getting "No systems Found". There has to be a config, or permission I am missing.
