I have 2, 16TB NAS units that I have been using for 4+ years, mapped via File Explorer as Y and Z. These are connected via ethernet in our home based business. Shortly after Christmas 2023, I came into my office and my PC had rebooted overnight, apparently from a Windows Update, despite being set to NOT install updates automatically. Once I logged in, both NAS devices were no longer showing up as mapped drives. I tried reconnecting, but only receive errors. I have been attempting to utilize the resources available all over Microsoft, but nothing works. I can see the units in File Explorer and one device I can even see the shares (see FileExplorer.jpg). However, I cannot map to either device, neither by using the device name(\WDMYCLOUDEX1400\bmmg) nor the IP address (192.168.0.xxx\bmmg). I have spent several hours with tech support from both Synology and WD, testing and ensuring they are set up correctly. Both sources say it is a Windows 10 issue. I have attempted to get help from various Microsoft sites I have been directed to, but have been unable to get help. The 'learn.microsoft.com site has allowed me to post questions and I have received a reply, but when I attempt to respond to them, my responses are blocked due to a 'code of conduct violation'. Nothing I have attempted to post has been harsh, or any type of offensive response, only attempting to supply further information or answer questions. can't even post "Thank you". FileExplorer.JPGI
