Well, I am going to jump out right in front of the truck and say that this is a bad idea! I personally HATE it when normal users have local Admin rights to their own machines!
Yes, the users can't break your network just by having local admin rights. They can't run "DEL *.* /S" on a server when they only have local admin rights; they can't disable a web site on a server; they can't delete shared public folders on the servers; they can't remove print queues.
All they can do is mess up their own workstation.
And to be honest, that is bad enough!!!
I don't know how many times I have heard users say things like, "I changed this setting and..." or "I installed this program and now...." or "I was looking around the system and..."
IMHO, it is a big mistake giving your users local Admin rights. If they need more than the normal user power, see if Power User status will do the job. Sometimes being a Power User will allow them to have all of the "advanced" functionality they might need. You can install as a Power User; you can modify some things as a Power User.
Yes, you can really mess up your system as a Power User, but I have seen it work so that it limits the users JUST ENOUGH to prevent regular workstation destruction!So, I am a vote in the negative for this idea, based off what I have seen over the years.
Absolute power corrupts absolutely....
user workstations!
