So I'm trying to use XP_CMDSHELL to set up my drive for using a backup. I already have the drive mapped, but per Link, I figured I'd need to mount the drive using net use.

But when I do, I get System error 53, 'The network path was not found.'

EXEC XP_CMDSHELL 'net use S: \\sql-backup'

I know this unc is accessible from the server because it is mounted as a network share on the sql server.

Any ideas why the unc is unreachable?
