I started working for a small title company about 8 months ago. When I came in everything was a mess. Everybody had admin rights on every machine. I came in and made a comment to my boss that it wasnt good. I showed thim what one machine could do and almost inmediatelly he gave me control over the network. Our network was so slow, spywares, adwares even viruses where crawling on our network. Once I cleaned it all up I locked dumped everybody down to users. It was a pain but after that uptime and network performance boosted up. Hope this helps!
