System Center Guide

When installing SCCM 2012 in a clustered SQL environment, you may receive the following error message during the prerequisite validation:

Configuration Manager only supports the use of primary FQDN’s, where the DNS hostname (first label in the FQDN) matches the NetBIOS hostname of the computer. The FQDN provided for this site system does not meet this requirement and cannot be used. Correct the FQDN and try again.

According to TechNet threads, this is a known bug and may be circumvented by using the /NoPrereq command line switch against Setup.exe in the folder SMSSETUP\BIN\X64.
