I am in the process of setting up a production Avast server and I am able to deploy the client, but none of the clients are licensed and communicating with the server. I have verified all ports are open, I have not exceeded my license count, and have tested by deploying over the network and manually deploying the client but nothing works. Any thoughts or suggestions would be greatly appreciated. We ran into this same problem on our test system but it was caused by exceeding our license limit.
Solved: I found a problem in the avast5.ini file where the file was using a server name that was not registered in our DNS. Once I changed the name to match what was in our DNS all clients are licensed.
