NTFS File System - NTFS provides Security and it is faster. FAT provides no security and is not appropriate for the Web Server (Project Node).
Microsoft Licensing will limit the number of clients connecting to IIS. The Limit is 10 simultaneous connections in Windows 2000 and XP Professional. In Windows 2000 and XP Server versions, the limit is dependant on your license (it can be unlimited). Vista Business is unlimited
