Experience : 5+ Yrs

Built and provisioned Windows servers (physical and virtual) — OS installation, role configuration (AD DS, DNS, DHCP, IIS), and post-build validation.
• Deployed and managed VMware vSphere/ESXi environments across the enterprise —
administered ESXi hosts, managed vCenter Server, and handled virtualisation incident resolution.
• Provisioned and configured virtual machines — allocated CPU, memory, and storage resources;
performed VM migrations, cloning, and template creation for rapid server deployment.
• Managed VMware snapshots — created pre-change snapshots, monitored snapshot growth, and performed consolidation to maintain datastore health and performance.
• Configured and managed virtual networking in VMware — created port groups, distributed virtual switches (DVS), and VLAN assignments aligned to enterprise network segmentation standards.
• Performed VMware vMotion (live migration) and Storage vMotion to balance workloads across ESXi hosts with zero downtime during maintenance and capacity changes.
• Monitored ESXi host and VM performance using vCenter dashboards — tracked CPU, memory, disk I/O, and network metrics; identified and resolved resource contention issues.
• Managed resource pools and HA (High Availability) settings in vCenter to ensure workload
continuity and failover protection for critical virtual machines.
• Configured and maintained WSUS infrastructure for patch approval, deployment scheduling, and compliance reporting across server fleets.
• Executed server backup and restoration activities; supported disaster recovery failover validation and restoration testing for critical systems.
• Analysed Windows Event Logs (System, Security, Application) to identify root causes and prevent recurring infrastructure incidents.
• Managed disk configuration — volume extension, partition management,



and storage optimization for enterprise Windows Server environments.

• Administered Active Directory (AD DS) including OU design, user lifecycle management, group memberships, delegation, and FSMO role management across multi-site domain environments.
• Designed and implemented Group Policy Objects (GPOs) for security hardening, software
deployment, user restrictions, logon scripts, and compliance enforcement enterprise-wide.
• Managed DNS zones, conditional forwarders, record management, and DHCP scope
configuration; troubleshot resolution failures and lease conflicts across the infrastructure.
• Monitored and troubleshot AD replication across sites using Repadmin and DCDiag, ensuring domain controller synchronisation and health.
• Resolved Kerberos, NTLM, and domain trust authentication issues in enterprise environments, minimising login failures and service disruptions.
• Administered SCCM/MCM for end-to-end patch management — configured Automatic
Deployment Rules (ADRs), Software Update Groups, and maintenance windows; tracked
compliance across server and workstation fleets.
• Deployed applications via SCCM using deployment types, detection methods, and device
collections; resolved deployment failures using CM Trace log analysis (ccmexec.log,
AppEnforce.log).
• Applied CIS security baselines, disabled unnecessary services, enforced compliance standards, and managed NTFS permissions across Windows Server 2016/2019/2022.
• Managed Hyper-V environments — VM provisioning, snapshot management, virtual switch, configuration, and performance troubleshooting.
• Automated Active Directory and server tasks using PowerShell — bulk user provisioning, group membership updates, password policy enforcement, and server health reporting.
• Managed end-to-end incident resolution and change requests via ServiceNow, maintaining SLA compliance and documenting root cause analyses (RCAs).
