We have 5 desktop HP all in one computers, one NAS, and 2 printers in our office, all hooked up on Cat6 ,after update 1803 we have had nothing but problems with devices not seeing each other, when you look in file manager at the network it shows all the device names but when you click on them some of them give a message saying 0x80070035 which is a network issue, when you unlpug the network and use wi fi only it shows everything and can connect to all devices from any computer, trouble is its so slooooowww, I have done a network reset, set the TCP/IP NetBIOS Helper to running, in HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSLicensing I have removed HardwareID and store, Advanced TCP/IP Settings / and clicked enable NET Bios over TCP/IP, reset router, still the same, anyone had similar issues?
