Hi, just about finished setting up a new DS918+, and will now use my old DS414 as a backup for the 918. I've always mapped to the shared folders on the NAS from Windows, but I can't map drives to both NASes from Windows 10 at the same time. I'm getting the following error in Windows "The network folder specified is currently mapped using a different user name and password". Both NAS boxes contain the same user accounts & associated permissions, and the shared folders have the same names on both boxes (video, photo, music, etc). So I can map \\ip_of_NAS1\music, but then can't map \\ip_of_NAS2\music until I delete the map of \\ip_of_NAS1\music. Doesn't make sense to me as both have different ip addresses of course. If I rename the first mapped drive from"music" to "backup-music" it makes no difference. Stumped so any help appreciated.
