I am lurking around on this forum for more than 2 weeks now. New to security situation, though an old timer computer user. I have tried few security programs in the meantime, and bought few of them in this short period. However, in the process I have messed up two of my laptops and need help. On both laptop I used to have: 1. Avast Pro 2. Outpost Firewall Pro 3. Windows Defender Presently I have: 1. Avast Pro 2. Windows Firewall 3. Windows Defender disabled. I have tried many AV, HIPS and Firewall in these two weeks or more. The Firewall I tried, beside Outpost Pro were: 1. CIS - Complete Suite 2. OA - Free Problem: I cannot access other computers or the NAS server on my network from either of these two laptops anymore. However, from any computers on my network, I can access both these laptops without any problem. Operating system: Windows 7 x64 Need help desperately to access other computers on the network and especially, the NAS server. Maybe, some setting. P.S. I have tried to uninstall the Firewalls according to the developers of the Firewalls.
