While running a SCCM prerequisite check it's giving following error.
I have gone through steps given in http://support.microsoft.com/kb/121007/en-us to solved above problem.
A new version of the Windows Update Agent is available
http://support.microsoft.com/default.aspx?scid=kb;en-us;946928
Windows Update Agent (WUA) 3.0 is required on Configuration Manager
2007 client computers so that they can connect to the Windows Server
Update Services (WSUS) 3.0 server and retrieve the list of software
updates that need to be scanned for compliance.
