Check before UnMapping Network Drive Letter

I have the following code to Un-Map a drive letter.  What I would like assistance with is code to determine if DriveLetter is actually a mapped network drive.

Public Function UnMapDrive(ByVal DriveLetter As String) As Boolean
          Dim rc As Integer

''''''' - code here to determine if DriveLetter is actually a mapped network drive '''''''

            rc = WNetCancelConnection2(DriveLetter & ":", 0, ForceDisconnect)

                 If rc = 0 Then
                Return True
                Return False
            End If

          End Function
