Oh thank you for the reply! I hope you have some ideas.
I can get the DSM to work on Windows XP in a heartbeat. In Windows 7 and 10, I can see the drive, I can see the folders, but when I try to map the folder, it asks for the Network Password. On Windows XP it is SAN_Name\Username. But from Windows 7 and Windows 10, the DSM is not accepting it.
