I've been looking at wireshark, and have a lot of UDP traffic to port 2557 (from 25322), the port is reportedly used for nicetec-mgmt, does anyone know what this is?
It's probably actually another service, application, or process rather than nicetec-mgmt (whatever that is). I would recommend either of the following two things:
Find the computer where this traffic is originating from and install Microsoft Network Monitor and start a capture.
Find the computer where this traffic is destined and install Microsoft Network Monitor and start a capture.
MS NetMon has an option to show the process responsible for the traffic so either one of these should help you narrow down what's responsible for this traffic.
