By "Vesta" you mean "Vista"?
According to Knowledge base Article #7152, Windows Vista Business SP1 is listed as being able to run Filemaker Pro Server 10. There are hardware requirements as well as software. For more info, see KB 7152, FileMaker Server 10 and FileMaker Server 10 Advanced System Requirements.
Windows XP clients should be able to linke to a database hosted by FMS on such a system.
