• Troubleshoot Windows server issues within the infrastructure support scope and document issues requiring AltaGas or Qualys support.
• Support approved network or connectivity changes through the applicable AltaGas process when a PoC test requires a new port, URL allow-list entry, or firewall change.
• Maintain detailed test records and risk entries, including evidence of success, failure, rollback needs, and follow-up actions.
• Contribute Windows server findings, risks, limitations, and recommendations to the PoC findings report.
• Coordinate with the Desktop Support Engineer, Linux Administrator, application owners, and AltaGas stakeholders.
