• Everything seems to be going well and Pre requisite passed with flying colors.
• But while installing Management Server in the middle it failed with Fatal error 1603 and all got rolled back and installation was aborted.It asked me to refer the scom install log while which just gave the error 1603 Fatal error.
• After investigating some time found that there is 1 pre requisite which Microsoft missed to do.Probably a bug.
• Microsoft.NET 3.5.1 is mandatory. If this is not install it won't say any errors while you run the pre requsite. But.But in middle install will fail.
• So before starting the installation of SCOM management Server Go to Add/remove programs and click "add roles" and select "Application Server"    and install.
