I would like to add my thanks to all those that have provided the help to resolve this issue. I replaced a Win 10 laptop with a Win 11 laptop and could not connect to my Win 10 Desktop. The Win 10 laptop & Win 10 Desktop could connect to each other without any issues. I followed all the advise/suggestions presented in this forum and got to the point where the Desktop could see and connect to the Win 11 laptop. The Win 11 laptop could ping by ip address or by name but could not find the Desktop when trying to map a drive.
The last suggestion involving the "set" command via the Powershell worked for me.
Thanks again to all who helped resolving this issue for me!!!
