I wrote this script to remote into windows servers hosting our integrations and test port connectivity.

1. create a .ps1 script with this content

#--for windows hosts-- output to array then dump array to file

1. create a csv called SourcePortDestinationTestCases.csv fill with your source, port, and destinations you have to be able to remote into the windows server for this to work. here's the csv format

Source,Port,Destination
ServerA,6000,ServerB
