We have about 23 Windows 7 computers at the office and I am using Angry IP Scanner to detect IPs.
Mine and about 4 other computers show up on the IP scan but all the other computers do not and are unpingable. Their connections are fine and everyone (pingable and not) is only running Microsoft Security Essentials for firewall/antivirus.
I'm wondering where I should look for settings to change to make these computers visible? I've tried changing the network for one of them from Work to Home with no success. Any advice?
