The format of a share is \\MachineName\ShareName - you've omitted the sharename, so the WNetAddConnection() will inherently fail. You need to specify both parts of the UNC.

BTW, WNetAddConnction() is for backwards comaptibility to Win16; I'd strongly suggest using WNetAddConnection2() or WNetAddConnection3() instaed - it allows you to specify a userid, domain and password, offering better support,and permitting you to not force the share to map to a local resource, logging into the UNC without tying you to a mapped drive letter,
