Doesn't the // indicate an NFS path? Or, is it SMB? Anyway, / is for one of them and // is for the other. Or, maybe it is just the way my data paths are set up; one is set to the entire drive and the other is set to a directory on the drive.
This happens to me when I switch between smb and nfs, and refresh. Evidently the old (nfs) entries stay in the library until you start a new library or manually delete them.
I was switching back and forth experimenting, I ended up deciding they both work well.
I can access smb on a windows machine using \\COMPUTER-NAME
maybe that is what u mean? The double frontslash in my case was purely accidental. smb://COMPUTER-NAME I think is identical to \\COMPUTER-NAME
