    I'll put it this way, I think the nuclear bomb would need to be heavily blessed by the past three popes before being dropped from orbit in order to have any noticible effect.

    Well, I have now replaced TMG with ISA, we'll see if it really was TMG that was the cause of all the issues.

    Was TMG a replacement for "ISA"?

    As it happens my blame may have been misplaced, ISA is in and while it is working a little better there are still issues. There is 'something' wrong in the network and I have no idea where to even start looking. My only option may be to just point all the clients directly at the router and let them connect directly to see if that works.

    Stupid internet, it would not be so bad except this school has decided to 'cloud' a bunch of their stuff therby putting all their most important stuff over the weakest possible link avalible. I really would like a chasum to open up and swallow various cloud datacenters around the world so that we can get back to a sane model that works rather than attempting to do the equvilent of pushing an elephant throught an unreliable bendy straw.

    TMG = Forefront Threat Managment Gateway 2010 which was the replacement to ISA (Internet Security and Acceleration Server 2006), the whole line is comming to an end though to either be integrated into Windows Server itself or being pushed into the higher end and cost product Forefront Unified Access Gateway (UAG).

    I don't know if you have a contract (SLA) with the internet pipe owners ? perhaps packetloss ? let them do some measurements ? maybe fire up wireshark on several locations ?

    Thanks, I'm thinking so. Wireshark is probably the next step along with opening up the SNMP stuff on the router (provider-owned) and seeing if that manages to give out any new information on the situation. Its just one of those dirty issues that is not easy to pin down and so a pain to resolve.

    Stupidly I still can't pin down the problems 100% to the dirty TMG box as there is a switch or two in the way that are dodgey but it seems to be the prolem of TMG.

    Symptoms, continuously dropping packets and choking out internet connections for single clients for up to 15 minutes despite killing off flood mitigation settings and installing every hotfix avalible.

    Balmer needs to be hit with his own flying chair, removing features from products and releasing tripe like TMG. If I can finally 100% pin it down to TMG I am going to push MS to refund our Volume liscence of it.
    Causing me nothing but trouble too... It was Viglen's answer to a question no-body asked!

    All I want for Christmas is my own network without hindrance from a "one-size-fits-all" provider!
