Socket is closed error during discovery of device

[AJugovic]

I'm getting the following message when trying to discover a device. The other devices in the IP range are being discovered, and we know this device is active. I tested the credentials on it, and the test passed. Port 135 is open. I've not seen this error before. Any help is appreciated!

Make sure for wmi 135 higher range ports are also open.
