Password Protected Sharing in Vista Ultimate

I had this feature turned off in the Network and Sharing Control Panel to
ease communication between machines in my home network. Now it is turned on
and when I tick it to turn off and click apply it remains activated. My
other machines are running XP Pro. This hasn't been a problem until today.

Anyone come across this and know a fix or work around?

Hi Michael:
Have you created a new user recently?

My OS: Windows Vista Ultimate OEM
I had the same problem, and from what I read on the Web, the only solution
at the time was to format my HDD and re-install OS to fix.

I found according to Web searches, that one of the problems to cause this
can be by not setting a USER password!
After formatting/re-installing OS, this problem returned the same day and
I'm sure I had passwords set for both of my USERs, but by going into
"Control Panel"/"User Accounts" and changing newly created USER password. (I
entered the same one I had previously - both Administrator Type).
I then rebooted computer.
So, only after re-entering a USERs password could I turn off "PASSWORD
PROTECTED SHARING" and it stayed off.

NOTE: It didn't prompt me for the old password when changing password which
I thought was weird (or maybe I was creating a password?). So maybe I just
had a momentory memory loss due to early morning (2-3am repairs) and I
didn't enter a password? (I could have sworn I had entered one).
That was over a week ago and I've had no more of this problem since.
Cheers Sharpy
