Install RU6(11.0.6000.550) for starters to prevent the problem from happenning again as this is a bug. The DelTemps.exe works but the problem is that is has to be run locally or using a remote execute tool like PSExec, and it takes hours if there are literally thousands of temp files. I created a VB script that I run from a web page that does it a little better, in my opinion, both methods work for me but they can run for several hours, like sometimes over 24 hrs. That is why I prefer the script as it works behind the scenes and doesnt bother the user.
