I upgraded the following: Mac OS 10.10 to 10.11.x Parallels 10 to 11 Windows 8 to 10 Now I can only see the Synology server as a device in Windows Explorer, but it does not appear in the Network section to access it. The Parallels Configure/Hardware/Network setting is "Default adapter" I'm guessing there is a setting in Parallels or Windows 11 that is effecting this.
