Hobbes Asked: 2011-03-30 08:19:27 +0800 CST LSASS.exe trying to communicate over port 80 2 We are running a standalone web server (Windows 2008 + IIS 7), and our antivirus is blocking LSASS.exe (C:\Windows\system32\lsass.exe) from making outbound connections over port 80. Why is LSASS doing this? (Should I be worried?) http security port-80 lsass
