RMTSHARE.exe (NT 4 Resource kit - download)

Manage File and Printer shares, local or on a remote server.
Although missing from recent Resource kits, the old version appears to work fine under Windows XP/2003.

Syntax
  Display all shares
      RMTSHARE \\server

  Display details of a specific share
      RMTSHARE \\server\sharename

  Share a Folder 
      RMTSHARE \\server\sharename=drive:path [options]

  Share a Printer 
      RMTSHARE \\server\sharename=printername /PRINTER [options]

  Edit an existing SHARE
      RMTSHARE \\server\sharename [options]

  Delete a SHARE
      RMTSHARE \\server\sharename /DELETE

Options
      /USERS:number 
      /UNLIMITED
      /REMARK:"text"
      /GRANT user:perm
      /REMOVE user

Notes: Either specify /Users to restrict the number of connections that can be made OR specify /UNLIMITED
You can include several /GRANTs in a single command line.
Enclose paths that include spaces like this
\\server\"long share name"="c:\long file name"

An alternative way to list remote shares with PowerShell:

# List the file shares on the remote server: SERVER64.

$shares = Get-WmiObject -class Win32_Share -computername SERVER64 -filter "Type=0"
$shares | foreach {
    $path=($_.path)
    $Description=($_.Description)
    $name=($_.name)
    $Caption=($_.Caption)

    "Share Name   : $name
     Source Folder: $path 
     Description  : $Description
     Caption : $Caption"
    }
