Horizon Troubleshooting Bootcamp (OHTB)

Horizon Troubleshooting Bootcamp course gives you the hands-on skills in resolving common issues that occur in a Horizon® environment.

This is a five-day combination course of Horizon Virtual Desktop Troubleshooting & Horizon Infrastructure Troubleshooting. You will engage in a series of lab exercises to bring existing environment issues to resolution. The exercises mirror real-world troubleshooting use cases.

These exercises equip learners with the knowledge and practical skills to manage typical challenges faced by Tier 1 virtual desktop administrators and operators, as well as advanced knowledge, skills, and abilities to troubleshoot Horizon infrastructure. This workshop teaches the required skill and competence for troubleshooting Horizon Connection Server, Unified Access Gateway, protocols, connections, and certificates. Horizon Troubleshooting bootcamp provides two challenge labs designed to present participants with virtual desktops and infrastructure issues that may arise in actual Horizon environments. The lab objective is to put into practice the contents covered during the training to create a working environment.
