Answer:

The Netstat command total failure is likely coming from the account you have configured not having the privileges to either run the netstat -anop TCP command or the command can be run but the output cannot be saved and then read from the ADMIN$ share. This can be verified by logging into one of these machines using that same credential that is being tested in the RN150, opening up a command line and attempting to run the netstat -anop TCP command. If this is successful, log into that same machine and run the full command below in which the output is saved to a file in the ADMIN$ share : cmd.exe /Q /c netstat -anop TCP 1> \\127.0.0.1\ADMIN$\filename 2>&1. If access denied errors are encountered on either of these, you have identified the issue.
