DX4000 with New PC Setup Shows Offline

Good Morning,
Sorry for the previous post. I had to rebuild from scratch my pc due to Intel’s bios update 2.2.1, but thank goodness Dell took responsibility and replaced the processor and HD. After reinstalling Win10 pro Ver. 1709 I could actually do a manual backup and it functioned correctly. I reinstalled MS Essentials 2012 and this morning I can not get the server to see my unit online, reports offline. I can not see anything obviously wrong so I am asking for some help if possible.
