TMG 2010 Error Code 10060 RRS feed

  • Question

  • i've setup TMG with three NICs

    NIC01- ISP 01, only gateway of ISP with lower Metric, no DNS

    NIC02 - ISP 02, only gateway of ISP with higher metric, no DNS 

    NIC02 - LAN, no gateway, DNS of internal DomainController.

    I've setup DUAL ISP Load Balancing, and it seems that it is working fine.
    BUt, time to time, i got this error message as in picture.
    The problem is showed in different PC for the same website, even for
    SOme PC could be open, some not.
    From TMG i could ping succesfullty to ping the same to internal DC, i could succefully ping to
    Also the clients where we have problems could ping to, but the webbrowser is not going to the website.
    I don't use Proxy Settings, so i dont understan why this happen, and how to fix it.

    I've created the rules to allow all access from internal to external!

  • Hi,

    Thank you for the post.

    On TMG server, you may run TMG BPA and do a healthy check see if there is any error message. Please also check if the internet access rule require authentication, if yes, the client should be configured as web proxy or firewall client type.
