Connection to network server

Roon will pick up files from my hard drive. However, it refuses to see my network server even though it will connect to it when I ask it to find files. Translation-the name of the server and file folder will show up but it will not allow a connection. Usually get message “drive is not accessible or file has been deleted.” Using form smb://name of server/name of folder with variations if that does not work. Occasionally I will not receive an error message but no files are transferred. Pulling my hair out. I have even tried to map the network drive but I probably did that wrong, but still no results. Using Windows 10 with Roan 1.1 if that helps.
