mount.cifs: bad UNC ...

[Albretch Mueller <lbrtchx@gmail.com>]

 I am unsuccessfully trying to mount a Windows Network share which (on
windows) advertises itself as using the following path
~
 \\315wcclassdc.wcclasses.local\users$\class1
~
 but this is what I am getting:

$ sudo mkdir -p /media/cifs

$ sudo mount -t cifs \\315wcclassdc.wcclasses.local\users$\class1 -o
username=class1,password=12345 /media/cifs
mount.cifs: bad UNC (\315wcclassdc.wcclasses.localusers$class1)

$ sudo mount -t cifs //315wcclassdc.wcclasses.local/users$/class1 -o
username=class1,password=12345 /media/cifs
unable to add mount entry to mtab
error 22 detected on close of mtab
unable to add mount entry to mtab

$ sudo mount -t cifs "//315wcclassdc.wcclasses.local/users$/class1" -o
username=class1,password=12345 /media/cifs
mount error(16): Device or resource busy
Refer to the mount.cifs(8) manual page (e.g. man mount.cifs)

$ sudo mount -t smbfs "//315wcclassdc.wcclasses.local/users$/class1"
-o username=class1,password=12345 /media/cifs
mount error(16): Device or resource busy
Refer to the mount.cifs(8) manual page (e.g. man mount.cifs)

$ sudo mount -t cifs \\\315wcclassdc.wcclasses.local\users$\class1 -o
username=class1,password=12345 /media/cifs
mount.cifs: bad UNC (\315wcclassdc.wcclasses.localusers$class1)

 How do I troubleshoot that problem?

 How do you probe a Windows FS from within Linux?
