• Monitor and tune server performance (Perfmon, Resource Monitor, Event Viewer/Event Log correlation)
• Troubleshoot Kerberos/NTLM authentication issues, time sync (NTP/W32Time), and DNS resolution problems
• Manage backup/restore and DR testing for Windows server workloads (Veeam/Commvault)

• Maintain build standards, runbooks, and change documentation (ITIL-aligned)

Skills/Must Have:

• 5+ years hands-on Wintel engineering (not just admin/support, genuine build and design experience)
• Deep Active Directory: multi-domain/forest, FSMO, replication, trust relationships
• Advanced Group Policy design and troubleshooting
• WSUS/SCCM/MECM patch management at enterprise scale
• Windows Server Failover Clustering
• PowerShell scripting to a proficient/advanced level (not copy-paste)

Desirable Skills:
