Just had my Forefront TMG 2010 console crash on me with the cryptic error message Refresh Failed: Member not found (0x80020003), rendering me unable to view or change any firewall rules.
It seems that Internet Explorer 9 is causing this. Since I couldn´t uninstall IE9, I had to find a workaround for the console error.
- Open “C:Program FilesMicrosoft Forefront Threat Management GatewayUI_HTMLsTabsHandlerTabsHandler.htc”
- Search for the 3 lines which contain “paddingTop”, and comment out each of them by adding “//” in the begining.
// m_aPages [niPage].m_tdMain.style.paddingTop = ((m_nBoostUp < 0) ? -m_nBoostUp : 0) ;
- Save the file, and open the TMG management console.
