I just had a firewall issue. After restoring the firewall and resetting it to default settings, it turns off Network Discovery & Printer and file sharing. If I try to turn them on and save the changes, it doesn't save when I go back in. If I disable the windows firewall, they turn on and my network shared video works. Can someone help me?
Do you still have the predefined rules option in Windows 7 firewall? If those predefined rules were tampered with then you will see this type of problem.
There is a way to fix the problem but it involves editing the registry.
Here is a thread with a similar problem, solution is in the next link.

Chev, you hit the nail on the head. My predefined rules were tampered with, and I couldn't change them. I added the registry entry in the first link and everything started to work again. I appreciate your help!
I'm glad that you reported back in Tom. This helps other people who find this thread to have confidence in fixing this ongoing problem.
Lately when I see this problem is has to do with the base filtering engine service being corrupted and needs to be repaired. This is usually caused from a virus.
The link below shows you how to fix this never ending problem, it uses the ESET repair utility for this.

Yup, in my case I believe it was a virus that deleted all of the default firewall rules. The Base Filtering Engine service was intact but all of the dozens of default rules were gone. While searching for a solution I've seen many cases where the Base Filtering Engine is missing or corrupted. Your link to ESET's ServicesRepair utility is appreciated. I've downloaded it for my toolbox in case I need it in the future.
Thanks again.
Tom
