Which version of Windows Server is required for installing the Okta Active Directory agent?

The correct answer is that Okta Active Directory agent requires Windows Server 2008 R2 or newer. This specification is important because it ensures compatibility with modern security and network enhancements present in later versions of Windows Server. Windows Server 2008 R2 introduced significant improvements in terms of performance, scalability, and security features, which are essential for the effective functioning of the Okta AD agent.

Using a version older than 2008 R2, such as Windows Server 2003 R2, poses risks, as it lacks the necessary updates and enhancements that are crucial for secure and efficient integration with modern cloud identity solutions like Okta. Moreover, Windows Server 2012 and later versions do offer notable improvements as well, but the requirement indicates that the minimum supported version is Windows Server 2008 R2. Therefore, while higher versions would also be suitable, the threshold for compatibility starts at 2008 R2.
