There are 3 possible main outcomes that we need to look for:

This indicates that the License Manager service is running on port 5093 and is listening for a connection. There is not a block on the inbound requests.
2) 5093/UDP open/filtered unknown
This indicates that the License Manager service may be running on port 5093 and listening for a connection, but is filtered or behind a firewall (blocked to inbound requests).
3) 5093/UDP closed unknown
