Windows Firewall Blocking Network Discovery and File Sharing
I have a wired network consisting of 3 Windows 7 Profesional computers and one WHS server. My network configuration has been in place for over 2-years without an issue. One of my Windows 7 computers has developed an issue where I can no longer access the the other two Windows 7 computers through Windows Exployer. When you go into the control panel and Networking and the Advanced network sharing and file sharing button are off, when I attempt to turn them on it does not let me turn them on (with Adminstrator privileges of course), keeps returning to the disabled position. If I disable the Windows firewall everything works, no problems.
I have ran the troubleshooting for network sharing and it ends up with the the Windows Firewall settings as incorrect, however the troubleshooter attempt to fix fails..
I am running Microsoft Security Essentials and also use Malwarebytes for virus and malware security. I have ran both these on full scans without an issue.
Any suggestion would be appreciated.
Thanks
