In the ADNM Console, under “Computers with Agent” there are listed four workstations, three of which show the green icon and one that shows a key icon.
I found this only because I was viewing the Antivirus event viewer in Computer Management for the computer with the key icon and saw lots of errors (actually the same two errors many times). They are CClient::PopupThread - GetConnection failed [0x2] and POP from server failed [0x7FFF0021, res timestamp: 0].
That’s odd, because I’m using ADNM with the product I bought. I’ve been able to create installation files with it and install them on workstations and those workstations are running Avast and have even caught viruses. And the status of the clients are showing up in ADNM on the server.
