NIS2011 Won't share folder on my home network all of a sudden

On my home network all of a sudden last week (about 8/11-812/2011) My mapped hard drives on my computer wouldn't connect. upon ALOT of trial and error (image attached) i finally Kind-of figured out where the problem is stemming from, On My desktop (house file server) NIS2011 Firewall seems to be keeping my computer from sharing the folders on the network so none of the computers can connect. I never changed anything but all of a sudden NIS just killed the network. What can I do to add the network into a "Trusted" area so it doesn't block it and I can have the computer protected and still be able to have the network like it has beeen for the past year or more.

 

This is from my Laptop Win Vista HP X64 ("\ \ Eugene-HP")

"\ \ Eugenes" is the house file server (Win 7 Ult x64)

 

Any help anyone can provide would be greatly appreciated.
