Our clients’ customer, AFBA Group, is a multilingual Business Advisory and Accounting Firm. The company was running an on-premises Windows Server 2012 R2 configured to act as a Remote Desk-top (RDS) Server. It was was deployed using Hard-ware Virtual Machine (HVM) Mode under Citrix Xen Hypervisor. The issue was that they were running it without an Active Directory Domain Services (AD DS) environment in place.An AD DS is the function in an active directory that helps manage users and their computers and helps admins organize data into hierarchies. AD DS provides security services, LDAP, SSO (Single Sign-Ons) etc.
