Scott, you know this stuff a lot better than I. It is an HP t5720, but this is what it says on the HP website: "HP Compaq t5720 Thin Client with Genuine Windows XP Embedded. The t5720 delivers desktop-like features and support for local applications. . . The processing power your workers need for a great server-based computing experience, whether running general office applications or your specific line of business software on a terminal server. . . Advanced connectivity features include a wide range of ports and support for options including smart card readers, modems, and other common options." It does indicate support for Citrix and RDP but also says it is "compatible with XP Professional." Has HP misled me?
