Overview

“Active Directory Troubleshooting” is designed for roles such as System administrators and IT operations and Help desk and support staff moving into administration. In 6 hours you work your way through dcdiag and repadmin, Analyzing replication errors and DNS problems in AD in a structured way – with plenty of practice and time for your questions.

Windows Server, Active Directory and Microsoft cloud services form the foundation for identities, workplaces and collaboration in most organizations. Hybrid scenarios with Entra ID, Intune and Microsoft 365 noticeably raise the bar for administrators. Our Active Directory Troubleshooting courses are for teams who want to run, secure and automate directory services, servers and endpoints reliably. You work in a provided lab environment on typical operational tasks and failure patterns, not on slide examples. The course runs online or on site, lasts one day and is offered at a fixed price per participant.

The course is delivered live – either online in a virtual classroom or on-site in our training rooms in Munich, Salzburg, Berlin, Augsburg, Hanover, Bremen, Stuttgart and Kaiserslautern. We can also run it exclusively for your team.
