I have installed a ASP.NET application in Windows 2003 server and need to remove readonly rights from a folder so that the users who access the IIS can write to this temporary folder. But everytime when i remove the readonly rights from the folder and save, next time when I open the older readonly right is enable. the color of the check box is gray. I have tried by all mean to make this work but it just won't work. The same ASP.NET system is working in Windows XP without any issues.
