Projects
Altiris patch solution (IT Management Suite Version 8)
Implemented Altiris (ITMS) 8. Used this tool to patch all the servers and workstations including Domain controllers and other critical servers.
Power Admin implementation
Implemented Power Admin (PA) monitoring tool to monitor Windows, Linux and ESXI servers. With this tool, 100% of the critical servers are proactively monitored and remediated issues such as Disk space, Ping down and service stop alerts.
SEPM Upgrade from 12.1 RU6 MP1 to 12.1 RU6 MP5
Upgraded Symantec Endpoint Protection Manager (SEPM) from 12.1 RU6 MP1 to MP5. SEPM is the main Antivirus for our environment. That reports and quarantines Virus and worm intrusion in the network.
Server patching compliance
Worked with Security team and patched all systems on a new environment. Achieved 100% compliance in ISO and Security audits for Pentest vulnerability tests.
Automation through PowerShell and PowerCLI Scripts
Automated repetitive tasks such as Disk space report generation, Host entry update (for a specific project - Altiris) using PowerShell scripts. VMware tools installation using PowerCLI scripts.
SEP reconfiguration to address severe network latency
One of the environments got severely affected with network latency issues. We found that Symantec endpoint protection was the cause of the issue. To address the issue, I have made changes in SEP heartbeat interval, Download randomization, SEPM updates storage limits and Client Virus scanning settings etc. This fixed the latency issue considerably.
Domain Controller recreation
On separate instances, Primary and secondary Domain controllers went down after server hardware related issue. They both went beyond repairable. Replaced two faulty additional domain controllers by performing Seizing FSMO roles and metadata cleanup with new ones in a live environment.
