I have more than twenty years experience supporting computers, networks, and end users in homes, small businesses, government offices, and Fortune 500 corporations. Most of that experience has been working with Microsoft operating systems (DOS and the many flavors of Windows) and software (MS Office, Active Directory, Exchange, etc.).
I bought my first computer in 1991 and beat my head against a wall for the next four years trying to figure the thing out. In 1995 I started my first real computer job in San Angelo, Texas, writing custom Excel applications and Access databases. After that, I worked in a tape library for a few months before moving to Denver to work for a software company. For the next few years I supported end users of a UNIX-based wholesale distribution software package, provided desktop computer support for a high-security government facility and a Fortune 500 company, manned a graveyard-shift help desk for the postal service, set up computer classrooms for a technical training center, built websites for a small business and a non-profit, and delivered the Rocky Mountain News to homes in the Denver metro area. In 1999 I began work as a systems administrator for a large network, managing servers, Active Directory, Group Policy Objects, and disaster recovery for more than fifteen thousand end users. I stayed there until the end of 2008 when I decided it was time to come back to Texas, where I did some independent consulting on anything and everything computer related. Among other tasks, I wired networks, set up email, removed viruses, fixed Macs(!?), and built more websites.
Presently, I am a senior systems administrator managing Exchange, Office 365, Skype, Active Directory, and Group Policies. Other than being MS certified, I have no affiliation with Microsoft.
