Hi All: I'm on a pretty fresh Intel new-build behind a D-Link DGL-4300 router on Cat5, no proxy. I'm using the Agnitum Outpost Firewall 2009 on XP3 Pro fully updated with no IIS installed. I am using OpenDNS on this rig, I disabled messenger service and have no FTP client installed yet. All my network functionality was fine under EAV v2.7 but I finally noticed that EAV didn't automatically upgrade to new core versions and I discovered we were up to v4, so: I un-installed v2.7, rebooted and installed v4. I used typical installation, and the new product updated itself fine. I didn't have any malware or virus problems on this PC, I just wanted to upgrade to the latest version. A full system scan has come up clean. Since upgrading I cannot connect to a website in Firefox or IE8, or fetch mail in Thunderbird. Both apps just cycle waiting for a page. I can transfer files between the problem PC and my backup rig through the router, but TSRs don't get their updates; the Outpost Firewall won't download its update scripts either. Skype won't go online. I have tried disabling Web access protection in EAV and restarting but it doesn't make a difference. I can ping Google from a command prompt, and I performed a cmd 'netsh winsock reset' and restarted, with no success. I have enabled complete permissions for EGUI.EXE and EKRN.EXE in the Outpost firewall, and EKRN firewall rules are correct, at 'Inbound TCP on 30606 - UDP DNS - Outbound TCP all'. I'm composing this on my backup rig with a TINY monitor, so I'm still searching the forum by saving pages and transferring them to the affected PC to review, so please forgive me if I've overlooked a prominent solution here. Advice, anyone?
