THE DETAILS: ISA Server 2004 Enterprise Dual NICs All Firewall rules are being logged --- with the last Firewall rule being: Rule name: HTTP Access Type: Array Access Policy Action: Allow Log requests matching this rule Protocols: All outbound Traffic From: Internal To: External, Internal Users: Domain Internet Users Schedule: Always Content Types: All content types All end users are running XP, with their browser (IE) configured to use the ISA as it's proxy server. All users who are allowed Internet Access are a member of the Windows Group: Domain Internet User Group Since it looks like the browser tries to make an Anonymous connection to the requested site first (12209) before using the authenticated login for that user, I'm getting "dual entries" in my logs -- an example would be: 10.194.80.106, anonymous, Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; .NET CLR 1.1.4322), N, 7/21/2006, 11:01:50, w3proxy, ISA2, -, www.oldnavy.com, 10.33.24.21, 8080, 1, 475, 4516, http, TCP, GET, http://www.oldnavy.com/Asset_Archive/ONWeb/content/0000/405/901/assets/footer_sundaysad_off.gif, -, -, 12209, 0x0, HTTP Access, -, Internal, External, 0x880, Denied, 7/21/2006 15:01:50 then followed by the attempt, using the authenticated user account: 10.194.80.106, FAHC\Mxxxxxx, Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; .NET CLR 1.1.4322), Y, 7/21/2006, 11:01:51, w3proxy, ISA2, -, www.oldnavy.com, 209.18.34.7, 80, 390, 571, 2908, http, TCP, GET, http://www.oldnavy.com/Asset_Archive/ONWeb/content/0000/405/901/assets/footer_sundaysad_off.gif, image/gif, VCache, 304, 0x800000, HTTP Access, -, Internal, External, 0xd80, Allowed, 7/21/2006 15:01:51 thus, creating a "duplicate" entry in the log. (we'll ignore that it's for Shopping!) THE PROBLEM: I don't care to log the internal-to-external, non-authenticated-anonymous attempts -- PLUS, a typical daily log for us is just topping 2GB PER DAY. If I can resolve this, I can cut my log file size by about 50% THE QUESTION: How can I prevent this specific "anonymous" entry from being logged? Would I create a Deny rule before my last rule (HTTP Access) and tell the rule to NOT log access from that rule? If so, how would I identify this "anonymous" user? Thanks.
