I do not understand this unexpected behavior: I'm making some experiments with VMWare Workstation 16 Pro and few virtual machines with Windows 10 Pro (20H2) and Windows Server 2019 Standard. I put Windows 10 machines on a domain and, for a while, I did not have any kind of trouble: I could click the Search Active Directory button in the Network window for opening the useful Find Users, Contacts, and Groups window. Now, without any kind of reason (I did not make any change and no computer has access to Internet) the Search Active Directory button is greyed out on all the computers, Server 2019 machine included
I can open the Find Users, Contacts, and Groups window, digiting
Rundll32 dsquery.dll OpenQueryWindow but how can I reenable that useful button? I do not want to install something on the computers, since the button had worked fine for a while on each computer.
MORE: Everything works fine: domain works fine and computers can see each others as usual: the only issue is about the Search Active Directory button and, repeat, no machine accesses to Internet and never I made updates
