What process is listening on a port on a remote server?

Today's inconvenience involved wanting to query a list of servers to find out what process was listening on a particular port. I'd like to be able to use a txt file or csv as input. 

serverA,443
serverB,8888
serverC,11008

So, I need to figure out how to find out the full path to the process that's listening on port 443 on serverA, port 8888 on serverB, etc. 

I didn't write a script to do so because I didn't have time.  But I am putting the question out here because someday I should be able to script this.  My quick search online revealed many simple scripts that I could cut and paste on a local server, but I want something that will query a remote server (difficulty: I don't have Powershell remoting enabled, so it would have to run on my workstation and remotely query the servers).
