Microsoft maintains an updated system requirements page for every Dynamics GP version. The following URL is specific to Dynamics GP 2010 and requires access to either PartnerSource or CustomerSource: https://mbs.microsoft.com/customersource/documentation/systemrequirements/MDGP2010_System_Requirements.
All of this information is updated as new versions and service packs of products are released and certified, so it is important to refer to the current information online when planning your implementation.
The system requirements are broken out into several categories: client requirements, server requirements and recommendations, terminal server requirements, and additional notes. The following sections will discuss each one in more detail.
