I haven't upgraded our system since 01/2017 until last night. After the upgrade, the sniffer sensor stopped getting data. I tried to remove the sensor and add it back it but now, it says there are no network adapters available. I am able to add a Windows Network Card sensor so I could not figure out why the Packet Sniffer sensor would not see the the network adapters on the probe machine. What could I be doing wrong?
