I just purchased NIS 2009 (updated to 16.2.0.7).
Immediately after installing it, my internet would get blocked…including network access to my NAT. After playing around with it and a few reboots it seems the problem is that the “Intrusion Prevention” blocks my router(!). For a minute or two after loading windows, my internet is working fine. Soon after it gets blocked.... completely. Not even DHCP goes through. If I disable Intrusion Prevention and reboot, it works fine again.
Any insights? It's crazy.
If it helps:
Vista Ultimate 32bit.
Connected via Ethernet to Router with NAT + DHCP.
Internet works fine with other machines connected to the same router.
