Connect with me at jgerstne@mindspring.comMy name is John Gerstner, and I am a System Administrator with 15 years worth of experience in Information Technology. I am looking to expand my network on LinkedIn and I'm also interested in learning more about employment opportunities for which I may be a good fit. With regards to my overall work experience, I have worked for the past 10 years in Wintel server environments supporting both medium and large environments ranging from 100 to over 700 servers. In my current position, I work with McAfee's ePolicy Orchestrator as a security administrator. I'm responsible for host intrusion prevention measures as well as antivirus/spyware/malware detection and removal. In my previous position as backup administrator, I ensured backups were working, implemented changes as to inclusions and exclusions of data for backups and tested upgrades and fixes as needed.. I’ve also implemented backup solutions in environments for the first time and performed the necessary steps to get backups working correctly. I also have extensive experience installing, troubleshooting and configuring Windows Server 2003 and 2008. My duties have included the configuration and resolution of operating system and hardware issues. Additionally, I have some experience on VMWare VI3. Throughout my career, I've advanced into positions of greater responsibility and excelled at meeting new challenges. I also like to think that I've left every environment in better shape than when I arrived. Please feel free to contact me to connect to my network at jgerstne@mindspring.com.Specialties: Some of my specialties involve working with McAfee's ePolicy Orchestrator. I also have extensive experience with backup strategies, mostly IBM Tivoli Storage Manager Client, EVault InfoStage, and Symantec Backup Exec.
