We have upgraded ARS to the latest version. It is working fine on the server but none of our clients can connect citing a timeout to the administration service:
"Failed to connect to Administration Service on 'ARServer.Domain.com'. The operation did not complete within the time allotted"
Check your Firewall rules.
Note: Starting with Active Roles 7.0, only bi-directional connectivity on port 15172 is required between the Active Roles Administration Service and any Active Roles Client.
