I am facing a problem with my ISA 2006... It is configured to allow everything, though none of websites is opening except for some sites like google For example when i open yahoo.com and enable the loging in the ISA, i would get a denied action on the HTTP request and below is more info about that log:
Denied Connection Log type: Web Proxy (Forward) Status: 12209 The ISA Server requires authorization to fulfill the request. Access to the Web Proxy filter is denied. Rule: Source: Internal (188.8.131.52) Destination: (184.108.40.206:80) Request: GET http://www.yahoo.com/Filter information: Req ID: 0d088078; Compression: client=No, server=No, compress rate=0% decompress rate=0% Protocol: http User: anonymous Additional information Client agent: Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.2; .NET CLR 1.1.4322)Object source: (No source information is available.)Cache info: 0x0Processing time: 1 MIME type:and eventually the page will not be displayed and here what i get from that page:
Technical Information (for support personnel) Error Code 10060: Connection timeout Background: The gateway could not receive a timely response from the website you are trying to access. This might indicate that the network is congested, or that the website is experiencing technical difficulties. can anybody help me in this issue plz???
Your ISA server is configured to require authenticated Web requests, either because the outbound access rule specifies it or the Web proxy listener is set to "require all users to authenticate". However, your clients are unable to provide credentials, probably because they are not configured as web proxy clients.

thatīs rigth Ian! Once you check this option you are saying to ISA, allow only authenticated users traffic and deny all other (anonymous). You donīt need to check this option to require ISA to authenticate users, you can just create a rule and aplly to an specified user set (other than All Users).
I disabled that option... but still i am not able to go over the internet.. here is what i get when i open www.yahoo.com

first, why are you using ISA to access webpages? I strongly do not recommend you to do it, because in this way you are making ISA susceptible to attacks. Second, use the following rule: "Allow HTTP/HTTPS requests from ISA Server to specified sites", make sure the site you are trying to access is in System Policy Allowed Sites domain name sets. Third, try to access other site than www.yahoo.com.
