Why did Microsoft change the supported client operating systems for the Legacy Client?
A. Microsoft is committed to supporting configurations that provide a higher level of security. For systems running Windows 2000, Windows XP, and Windows Server 2003, a higher level of security is provided by the Advanced Client. The goal of the Legacy Client is to allow customers to manage Windows 98 and Windows NT 4.0 SP6a systems. Support for these operating systems continues with SMS 2003 SP1; however, for all later versions of operating systems, the Advanced Client allows customers to benefit from a more secure solution available for SMS clients by default.
