"Terminal server requirements
Microsoft recommends using a dedicated Terminal Server/Citrix Server when running Microsoft Dynamics GP 9.0. There might be performance losses if Microsoft SQL Server is running on the Terminal Server/Citrix Server. To avoid performance losses, it is highly recommended to have two separate servers: one server with Terminal Server and/or Citrix, and one server with Microsoft SQL Server."
