As a Windows administrator, what tools do you feel you cannot live without?
Currently I have been using (D)DoS-Deflate to manage such situations on numerous remote servers, along with Apache JMeter for load testing.
Overall it has been working fairly well, although I'd like to hear some suggestions from gurus who have been working with these sort of circumstances for longer than I have. I'm sure those working in the web hosting business have had their fair share of dealing with these situations. So I'm wondering what the best practices are to approaching these sorts of problems in a corporate environment?
