  • isa Server 2006 Issue

    This sound crazy but many of the pages I browse stop loading as the browser says "connecting to pagead2.googlesyndication.com" This happens all the time for me. For example, on this site: http:www. paperpk .com every single page halts for at least 8 or 9 seconds while the browser tries to connect to pagead2.googlesyndication.com. It makes it virtually impossible to browse the site comfortably. It's like browsing on a 14.4 bps connection.

    This happens on Opera and IE Mozila FireFox . IE doesn't give a message, but Opera does say: "connecting to pagead2.googlesyndication.com" and just sits there with a blank screen.

    I am using isa 2006 Enterprise Server on both client pc and server PC have the problem

    How is ISA Setup, Dual NIC Edge Firewall or something like that?

    Check your network adapter settings and bindings as well, things like having DNS servers configured on the external network adapter causes odd issues. This link from isaserver.org has all the info on configuring your interfaces.

        You shouldn't have DNS servers configured on the external (public facing) adapter, that's why the internal network card (the adapter where the internal DNS Servers are located) at the top of the binding order, with perimeter networks next and then the external adapter last.

        If your event logs or ISA BPA (Free download from MS and well worth having on your ISA Servers) is flagging up lots of errors about Proxy Chain Loops then it's usually a sign of incorrectly configured adapters. This issue often presents itself with odd errors like the ones you are getting, usually as a result of DNS resolution issues.

        I'm not familiar with this googlesyndication link though, sounds like some sort of adware type site.

          I believe the googlesyndication.com domain is to do with Google AdWords.

              Re: isa Server 2006 Issue

              ok i my isp give me 2 dns server address and i configure these on my domain controller forwarder and also on my external nic on my isa server i forgot to mention i have to isa server configure with with this configuration

              Server name ISA1 Server name ISA2
              lan1 10.96.0.1 Lan1 10.96.0.50
              lan2 10.32.0.1 Lan2 10.32.0.50
              external lan3 External Lan3

              External lan3 is configure as public ip with default gatway and dns ip on both machine i use custome subneting on my internal lan

              binding order is same as i mention lan1 lan2 and external lan3

              initially i setup this network its working fine i happening only when google adsesen page is open and page not load completely googlesyndication.com

              may be this is dns related error because site have the same problem when i connecting to internet directly on my server with public ip may be i call my isp

              but i block this site for now http://*.googlesyndication.com/* in isa access policy no site is open and some google adds are not showing. but at least site is opening properly on client machine

                Re: isa Server 2006 Issue

                So again remove all DNS settings on your ISA server except on your internal NIC to your internal DNS servers.
                MAybe this might help:
