Windows 7 64 bit SP1 unable to check for updates - 80072EFD error

A new notebook Samsung 900 series. Replaced the HDD with Crucial M4 mSATA 256GB. I used the win7 OEM recovery to re-install on the new mSATA. Instllation was fine. I manually updated the drivers from the Samsung site. I using win7 pro firewall configured for browsers and svchost.exe (initially for windows update and later for all programs and services). I use MSE and MBAM Pro realtime. I checked the MS site and allowed exceptions to their weblinks in Internet Options. The MSE and MBAM update without any issues. Win7 is validated as SP1. I am unable to run the win7 update since last night. I am getting the captioned error. I pinged their site from the elevated and normal command prompt. The ping returns a failure, while I can browse any website. I tried MS Fixit. It does not run for the same error. I repaired and upgraded without any success. The updates at the upgrade phase also fail for the same error. I seemed to have exhausted all options. MBAM Pro and MSE do not return any malware/virus.

The firewall rules are similar on the desktop and the two notebooks. The update problem (connectivity) is showing only in the Samsung Notebook, while MBAM Pro and MSE are nicely updating in Samsung as well.

Please advise.

Thanks

Problem Solved. I booted from the flash drive, reformatted the hard drive and re-installed win 7.
