No valid source or MP locations could be identified to download content from

Most likeley we will get below error msg when installing SCCM client on workgroup computers;
"No valid source or MP locations could be identified to download content from. Ccmsetup.exe cannot continue.
Failed to parse '"C:\Windows\ccmsetup\ccmsetup.exe" /runservice /source:"\\SCCM2012\sms_LAB\Client" "SMSMP=xx.xxxx.xxx"' with error 0x80004005"
CcmSetup failed with error code 0x80004005.

Various factors may cause this problem.
Few key points to check;
- Boundary is in place
- Boundary assigned to a boundary group and assigned a site server
- Required ports are opened
- entered correct SMSMP FQDN
- Use correct commandline when running CCMSetup.exe as below;
