What is the minimum operating system requirement for the RSA Archer Web Server?

Microsoft Windows 2000 Server predates the minimum supported baseline and lacks the required IIS and .NET Framework versions needed by RSA Archer.

According to RSA Archer platform system requirements, Microsoft Windows Server 2003 is the minimum supported OS version for the Archer Web Server tier. This baseline was established based on the .NET Framework and IIS version dependencies required by the Archer application server at that release level. Earlier Windows Server versions do not meet the prerequisites for supported deployment.

Windows Server 2003 R2 is a valid supported version but is not the minimum - the non-R2 release of Windows Server 2003 is the floor.

Windows Server 2008 is a supported and recommended version but is above the minimum requirement, not the minimum itself.
