ConfTool and IIS. Things to check:
- Is it possible to lauch NSLOOKUP?

- Is it possible to make the upload directory writeable?

- Can PHP parameters be modified with set_int()?

- How long is the CGI timeout? (for uploading files...) It is usually 3 or 5 minutes, that is
  often not enough (e.g. for sending emails).

- If https is used: Check if downloads and data export work properly!
