I have a wired home network between my desktop and my laptop. I'm running Windows 7 on both, x64 on the desktop and x86 in the laptop. On the laptop, I have ESS 3.0.684.0 and on the desktop ESS 4.0.424.0. My ESS 4 log shows endless list of the following messages: 5/9/2009 6:41:30 PM Communication denied by rule 192.168.1.100:55732 18.104.22.168:1900 UDP Block incoming SSDP (UPNP) requests PID=2604 NT AUTHORITY\LOCAL SERVICE 5/9/2009 6:41:30 PM Communication denied by rule fe80::54b2:1eb7:2ea:584a.:55729 ff02::c.:1900 UDP Block incoming SSDP (UPNP) requests PID=2604 NT AUTHORITY\LOCAL SERVICE Every few seconds. Seems like its a legitimate system request. I have the IP/Subnet set up a trusted zone, so why would ESS deny this communication request? I noticed that a similar thread was posted earlier, but didn't find anything there to shed any light on this issue. Any help would be appreciated. THNX.
