"Reset" random in class

So the task was to make a program that selects three different chest pieces (color + piece) using Enums. I made one instance of a Random object but of course this gives the same number throughout the execution of the code since I only initialized one int holding the random number.

Now my question is, is there any way you can reset it (update/modify the seed) or something like this during the execution so I don't have to create x amounts of int (in my case) to hold the random numbers?

For example: Every time my int chestpiece is used it would reinstate itself.

Is this possible or do I have to create several chesspiece int's (in my case) in order to fix this.

        private static void Main()
    {
        int chesspiece = Rand.Next(1, sizeof (EnumChestPiece) + 1);
        int color = Rand.Next(1, sizeof (EnumColor) + 1);

        EnumChestPiece firstPiece = (EnumChestPiece) chesspiece;
        EnumChestPiece secondPiece = (EnumChestPiece) chesspiece;
        EnumChestPiece thirdPiece = (EnumChestPiece) chesspiece;

        EnumColor firstColor = (EnumColor) color;
        EnumColor secondColor = (EnumColor) color;
        EnumColor thirdColor = (EnumColor) color;

        Console.WriteLine("{0} {1}", firstColor, firstPiece);
        Console.WriteLine("{0} {1}", secondColor, secondPiece);
        Console.WriteLine("{0} {1}", thirdColor, thirdPiece);
    }

    private enum EnumChestPiece
    {
        Pawn,
        Knight,
        Bishop,
        Rook,
        King,
        Queen
    }

    private enum EnumColor
    {
        Black,
        White
    }
