Program to monitor network sharing?

I'm looking for a program that will alert me when someone is trying to access the files im sharing on my pc. I've got Comodo Firewall which tells me the ip of the pc connecting to my pc, but im looking for a program that will tell me the name of the pc trying to connect to me and exactly what files its trying to access.
Any ideas?

thanks

Not sure if this will help you ?

Network Share Connection Monitor

Would you be looking for freeware software ?
