I can't access my Windows network shares anymore! People tell me to use the smbmount command, but it doesn't work!

Modern versions of Linux use a type of Windows file sharing called "The Common Internet File System" (CIFS). Instead of using "smbmount", try:

mount -t cifs //1.2.3.4/share /mnt/somedirectory

For more information about this, in a terminal you can do:

man mount.cifs

Note that CIFS can't resolve Windows computer names, so you're better off using their IP addresses.
