I know what your thinking... Is this guy for real? Everyone being an administrator would be insane!!!
Regardless, the question has come up in my department. We support 2000+ users in an academic environment. I try to explain the importance of limiting access to limit liability and decrease the amount of service calls related to viruses and user error. Sadly that isn't enough.
I am reaching out to the TechNet community to develop an extensive list of Pros and Cons on "Why can't everyone be an Administrator?"
What would the advantages be if every user was an Administrator? What are the disadvantages? Feel free to chime in with your horror stories!
