    Over the last 6 years I have been working as a system/network analyst. I know everything about Active directory with windows server 2003 and 2008. I just finished with a nice sharepoint for the office and everyone likes it. As a network admin I know a lot about office applications specially Microsoft Access. I have touched everything in IT and can do a lot more than what I describe in this first paragraph which are what I do on a daily basis. For example as a CCNA I can configure routers and switches to make your network function the way you want it.  less
