I have a server that is not acknowledging the UDP messages sent to it by it’s Relay. Client and Relay are both v10.0.5.
We used WireShark on the Relay to verify that the Relay is SENDING the UDP message, and WireShark installed on the Target Endpoint shows the UDP message from the Relay is being received by the Windows system, but BES Client never acknowledges the UDP message in it’s logs nor does it respond to the Relay as expected.
When I say UDP messages, I’m including both a New Targeted Custom Action, and a Forced Refresh attempt from the Console as a Master Operator.
Other machines in the same subnet seem to be working fine, acknowledging their New Actions and the Forced Refreshes.
Anyone have any suggestions on where I can/should look next? GPO is controlling the local Firewall, and there is currently a rule to allow the BES Client traffic inbound on UDP…
