Thanks Ramchandra for suggestion. I solved the problem now. I was not allowed to modify those folder options (you mentioned in #1) despite having all administrative priviledges because that is available only in XP professional edition. My XP was a home edition so, I needed to go into safe mode to do that. Once I knew the reason, then it was just matter of click. So easy, couldn't believe, though it took about 3 hours to look into additional information, wait until rebooting a couple of times and changing the ownership of the folders.
