Network sharing not working

Sorry i wrote something wrong

It runs the troubleshooter, then goes to a network troubleshooter and says something about "some homegroup issues can be network related"

What is way weirder, is that my laptop is visible on both my main PC and my Media Center, in the network tab in explorer.

Simply my main pc and media center can't find each other/work together

Homegroup not working on all of them.

Well i'm giving up, i can stream the vids via WMP instead or transfer the movies/files using my external HDD or USB pen

Anyways thx for your help aem :)

Well for now, i give up.

I will be installing windows 7 on another partion soon anyways, so it might work with that partion
