While working as a consultant, he has supported Apple Macintosh, IBM OS/2, Linux, Novell NetWare, and all Microsoft operating systems from MS-DOS to Windows Server 2012, as well as hardware from most of the major manufacturers.

Timothy Warner is an IT professional, technical trainer, and author based in Nashville, Tennessee. Tim’s been involved with computers in one way or another since 1982, when he received a Commodore 64 as a birthday present.

Tim considers himself an IT generalist because he enjoys practically every facet of information technology. Since entering the field in 1997, Tim worked a variety of job roles in the education and enterprise business sectors: PC repair technician, systems administrator, technology developer, and software architect.

Some of the certifications Tim holds include the CompTIA A+ (since 1999), Network+, Security+ and CTT+; Microsoft MCSE in Windows Server, SQL Server and SharePoint Server; and various Apple, Cisco, and Novell titles.

When he’s not working, Tim loves composing on his guitar (he lives in Music City, USA, after all), and spending time with his wife, Susan, and daughter, Zoey, and their animal menagerie.
