Is there a way to determine which service (in svchost.exe) does an outgoing connection?

I'm redoing my firewall configuration with more restrictive policies and I would like to determine the provenance (and/or destination) of some outgoing connections.

I have an issue because they come from svchost.exe and go to web content/application delivery providers - or similar:

5 IP in range: 82.96.58.0 - 82.96.58.255      --> Akamai Technologies         akamaitechnologies.com3 IP in range: 93.150.110.0 - 93.158.111.255  --> Akamai Technologies         akamaitechnologies.com2 IP in range: 87.248.194.0 - 87.248.223.255  --> LLNW Europe 2               llnw.net205.234.175.175                               --> CacheNetworks, Inc.         cachefly.net188.121.36.239                                --> Go Daddy Netherlands B.V.   secureserver.net

So is it possible to know which service does a particular connection? Or what's your recommendation about the rules applied to these ones?

Update:

netstat -ano& tasklist /svc help me a little but they are many services in one svchost.exe so it's still an issue. moreover the service names returned by "tasklist /svc" are not easy readable.

(All the connections are HTTP (port 80) but I don't think it's relevant)
