Coldfusion 8, Windows 2008, IIS7
I've just spent a fair amount of time trying to work out why a model glue app that we have on a windows 2003 machine, is grinding to almost to a halt on out new windows 2008 box. After trying lots of different things including installing a new version of Java, downloading the most up to date versions of ModelGlue & ColdSpring etc it seems to be that the problem is simply that ColdFusion was not installed as administrator.
So, when installing on windows 2008, always make sure you right click on the installer and then select 'run as administrator'.
