I have a Windows Network sharing issue. My desktop runs Win 10 My laptop runs Win 10 My HTPC runs Win 7 All 3 have shared folders with Everyone permissions Read & Write Network sharing options are all set to the same/proper selections. My desktop & HTPC have been networked for many years, no issues even after a Win 10 upgrade on the desktop. I'm trying to introduce my new laptop to the network. Everything shares without and prompts except the laptop to the HTPC. When trying to access shared folders from the HTPC through the laptop I get a Win10 Security box prompting for Network Credentials U/N & P/W. This doesn't occur when performing the same task on the desktop and the HTPC either way, nor between the desktop and laptop either way. I find this very strange. Any help would be great. Thanks.
