Q: What is the appropriate MS operating system product for me to license and use for multi-user computing with SPEED products:
A: Microsoft Windows Server products are the operating systems licensed, designed and supported by Microsoft for multiple simultaneous users. To work with SPEED products, you will need to license and use Windows Server 2003 R2 or Windows Server 2008 today. In the future, you will be able to license and use Windows Server 2008 and Windows MultiPoint Server 2010 to work with SPEED products.

Q: Can I run Windows XP instead of Windows Server software if I want multiple simultaneous users to access and use the operating system software?

A: Only under very limited circumstances. If you (the customer) have licensed the appropriate number of Windows Server operating system and associated Client Access Licenses for simultaneous access by multiple users to the Licensed Computer, you may install and run the SPEED vSpace Software on a separately licensed Windows XP Client operating system in lieu of the Windows Server operating system. You may only install and use either the Windows Server operating system software or the Windows XP Client operating system software but not both. Note that while Microsoft allows this limited use of the Windows XP client operating system configuration under these specific circumstances, support for SPEED’s  software running on Windows XP is solely provided by SPEED. Microsoft does not provide any support for SPEED Software or for the Windows XP Client operating system in this configuration; you should seek support from SPEED for issues relating to the SPEED Software and its use with the Windows XP Client operating system.

Q: Can I run Windows Vista, Windows 7 or any other Microsoft client operating system product to allow multiple simultaneous users to access and use the operating system software?
A: No, that is not permitted. You should instead purchase and run the Microsoft Windows Server operating system software that is appropriate for your needs. You must also obtain the appropriate number of Microsoft client access licenses that are necessary for the number of users or devices that access and use the server. Only Microsoft Windows Server software is licensed, designed and supported by Microsoft for multiple simultaneous users.
