Introduction

An Active Directory (AD) domain is a logical grouping of network objects (like users, computers, and groups) that share the same Active Directory database and are managed by a single administrative unit. 

There are several AD domains at the U of A including:

• sts.ad.ualberta.ca (STS) (also called Central Domain)
• engineering.ualberta.ca (ENGG)
• ualibrary.ualberta.ca (UALIBRARY)
• registrar.ualberta.ca (RO)
• med.ualberta.ca (MED)

This article was written to help readers know if their computer is part of an AD domain.
