Hello all, I have a couple of servers with TMG on it and was trying to install another one to make it part of an existing array. First of all, on ISA 2006 if my memory is not that bad, there was an option to install and while installing choose if that box was going to be part of an array, so we could pick the CSS then which array you wanted to join (or created a new one), etc..... On TMG I found the only option to be: Installed as an stand alone TMG server and then from the console choose to join an existing array. If I'm wrong on that please anybody let me know. But besides that, I tried to install this particular TMG server 3 times already and before reinstalling the entire OS I wanted to ask for help. Every time I'm running the installation, when the wizard is on "Additional Components (Estimated........)" the installation fail with this error: - Microsoft SQL Express 2008 (reporting instance could not be installed). As a result, Forefront TMG installation cannot be completed. Any help will be appreciated.
