Ofcourse, thank you very much for bringing me the solution of the use of Dial-a-fix. I am very glad with your advice to get the permissions straight again. I hope you accept my apologies. It was not my intention not to mention my thanks, but after trying DAF and the surprise of dissapearing accounts, I had no time anymore to test XP's WSH and did a systemrestore, in order to let other users use the PC with their own accounts. I have only used registrar to check the permissions of the remain accounts. After that I have write a quick respons of my experience and went away. I'm intent to use Dial-a- fix again if I have more time to test XP as soon I have the opportunity to do this without disturbance of regular users of the PC.
