By default, all cells are protected when sheet protection is enabled.

Hit CTRL + a(twice in 2003) to select all cells.

FormatCellsProtection. Uncheck "locked" and OK out.

Select the cells you want protected and FormatCellsProtection

Check "locked".

ToolsProtectionProtect Sheet. Note the options when protecting.

Supply a password and OK.

Excel's internal security is weak but this will prevent overwriting by accident.
