- "Finding different settings can be difficult if you don't know where to look."

What do I think about the stability of the solution?
Stability seems good.
What do I think about the scalability of the solution?
We have not needed to scale out with it, as we use it for very lightweight things.
How are customer service and technical support?
I have not needed to contact technical support.
Which solution did I use previously and why did I switch?
I have tried other tools (such as Apache), and found that IIS is more stable and easier on the memory for low resource systems.
How was the initial setup?
Initial setup is straightforward for a basic setup (e.g. one host hosting HTTP traffic), but can get more complicated the more features you want to add (e.g. Windows Authentication, HTTPs, web farm, etc.).
What's my experience with pricing, setup cost, and licensing?
It is licensed with your Windows installation which makes it relatively cheap if you already have a Windows Server sitting around.
Which other solutions did I evaluate?
We also evaluated Apache, but found that IIS was easier to set up for what we wanted.
What other advice do I have?
Give it a shot. The features are included for free with Windows, so test it out. If you are unhappy, it is easy to disable and switch to a different solution.
