My first activity after building any system is to backup a HDD image. Too many years of blow ups I guess. I reloaded both the file server and my PC to their original images. I discovered that if you go into the properties of a HDD that is networked, you can setup a access for "Everyone" with "Full Control". It seems that security tab overrides the share/permissions authority, read that somewhere on a MS site. This has allowed my backups on both my wife's and my PC running Win8 Pro upgrade to work perfectly again. Rather drastic option but the most pain is loading the self-booting CDROM that allows me to overlay a original image of the OS including any and all packages that had been installed on that system. Having spent 38 years...
