• Performing all duties of a shipboard IT Manager in the datacenter testing environments. Driver’s Alert / Robert Half Consultant, Deerfield, Florida February 2014 – Sept. 2015 Systems/Network Administrator

• When I started at Driver’s Alert I found a network with no licensing, no network management or monitoring, no security, no help desk, no comprehensive backups, and no asset or patch management. There were production servers that scattered between the office and the data center on severely underpowered Dell r320 servers. Virtually no virtual environment organization at all.

• Patch management, firmware, IDRAC drivers, and BIOs upgrades for servers were five years behind and were disabled at the local OS level. DNS was full of errors and no attempt to audit it had been done in many years. I audited and fixed all DNS errors.

• Many production servers were still running 32bit operating systems. I also discovered a 2007 Exchange server that was not replicating in both directions causing a major problem in the attempt to upgrade to 2010 Exchange servers. Their SQL production servers were also acting as the domain controllers causing serious performance issues with SQL and domain replication.

• A complete overhaul of all facets of the network configuration and design had to be performed. In the time that I was there I brought Driver’s Alert up to an enterprise level network. When I was done there was a very small footprint with all servers in the data center for optimal performance of all production, development, management, and testing servers.

• The first thing I did was to evaluate all the scattered servers and determine which ones were enterprise level servers and could be refurbished to host a large Hyper-V environment. I found three Dell PowerEdge R610, two Dell PowerEdge R710, and two Dell PowerEdge 2950s.

• I started by building a Microsoft Systems Center Operations and Configuration Manager server and the Systems Center Virtual Machine Manager on one of the R610s. This enabled me to move virtual machines around while upgrading the other hosts with 96 gigs of dual ranked memory, new hard drives, and raid configuration. Then convert all existing physical production and testing servers in the office to virtual machines and move them to one of the Enterprise Hyper-V clustered hosts in the data center.

• I purchased an HP StoreEase 1640 NAS. Then installed twelve 2TB Seagate Constellation hard drives and 32 gigs of memory and configured two raid 5 containers. Then I took two Dell PE2950s and refurbished them by rebuilding operating systems and installing bios, firmware, and driver updates for the hardware. I then built a redundant CA ARCserve UDP backup solution for all physical and virtual systems. This included Bare Metal Recovery built on Microsoft ADK development. Network Administrator, IT Computer Systems

• I managed all firewalls, switches, and routers and kept backups of all configurations. I developed a complete asset management system for all devices on the network.

• I built, configured, and managed a McAfee EPO (EPolicy Orchestrator) server including the McAfee Security for Microsoft Exchange (MSME) spam filters. This system updated DAT files daily and ran nightly and real time scans for all workstations and servers.

• I built, upgraded, and managed the Exchange organization from one 2007 to three 2010 servers in a DAG configuration with a Kemp load balancer for performance optimization.

Included IP configuration (static/DHCP/number), make, model, and mapped locations of all computers, servers, routers, switches, firewalls, printers, and security cameras. Also, user ID, username, mapped location, department, and phone extensions.

• Managed all help desk crew for efficiency and accuracy. Developed new procedures for the insertion of Acronis imaged systems to the company domain for accuracy. Worked extensively with help desk diagnosing and repairing hardware and software issues. Also, set up new users, user system profiles, emails boxes, scanner access, phone extensions, access cards, and necessary software for departmental functions.

Network Administrator, IT Computer Systems

• Retroactively analyzed errors on twenty-five 2003r2 and 2008r2 enterprise servers on a daily basis to optimize performance and uptime. Reconfigured DC servers for Global catalogs, raised PDC from 2003 to 2008, and reconfigured DNS entries in the NIC settings for optimal network performance.

• Upon arriving at Kahane I found that Group Policy GPOs were not functioning properly. After resolving the SYSVOL replication problem and the DNS errors I audited Active Directory. I found many overlapping and misconfigured GPOs and computers in containers that are not subject to GPOs. I then removed 800 systems that did not exist on the network anymore. I then restructured the OUs to the organizational outline. Then I moved all users and computers into their prospective OU containers and applied new GPOs and logon scripts according to the established company policies. Installed ADMX templates and configured Office 2010 specific GPOs and GPPs.

• Kahane had thousands of emails daily and there were always issues. I worked with the McAfee MX logic email cloud security service, Barracuda email archiver, and other methods to track and resolve delivery, spam, and virus quarantine issues.
