Task Server installed on Symantec Management Platform (SMP) unable to bind on ports 50121 & 50124
Another remote task server i.e. site server works as normal.
Client Task agent for SMP server points to its 2nd Task server NOT itself i.e. registered Task Server.
Customer had proxy in use, and that was raising proxy errors even though we knew ports were not binding.
"BaseXmlHttpCallback Exception: System.Net.Sockets.SocketException: No connection could be made because the target machine actively refused it 127.0.0.1:50121
at System.Net.Sockets.Socket.DoConnect(EndPoint endPointSnapshot, SocketAddress socketAddress)
at System.Net.Sockets.Socket.Connect(EndPoint remoteEP)
The following proxy errors were found misleading for port binding issue.
Description: ClientTaskServer.RegisterTaskServer(): Failed to register: System.Net.WebException: The remote server returned an error: (407) Proxy Authentication Required.
Description: NotificationServerWebConnection.FigureOutCredentials(): Credentials in Agent registry were invalid, or there was an error connecting to the server.
Description: NotificationServerWebConnection::CheckCredentials(): Credential check for "_Altiris" failed: System.Net.WebException: The remote server returned an error: (407) Proxy Authentication
