I have been administrating PCs since 1987. Have begun with MS-DOS, Novell Netware and peer-to-peer networks and IBM compatibles, recently administrating all the types of Windows (from 3.10, W95, W98, NT 3.51, NT 4, CE and learning about Win 2000) and Novell networks. Recently, several Linux and MacIntosh computers administrated as well.
Some certificates achieved, e.g. Cisco Certified Technician and Premier Reseller.
