Vista Permission to not Change Permissions

Hi All...

pulled a bit of a moron move last week.

I have a external array attached to a Dell system which we have recently
upgraded to Vista Ultimate 32bit.

To make the the files on the array available to everyone on the network, I
set up sharing so that it was avaiable able to "Everyone"

This worked great.

Then I thought I'd take it a bit further and decided that I didn't want
"Everyone" to have full control and set the permisions such that "Everyone"
couldn't delete files and ....here's the kicker...change the permssions.

Well "Everyone" includes me as the adminstrator.
Now I can't seem to change the permissions back.

With Microsoft's help I was able to change ownership of the volume and it's
files to a different Adminstative account on the system.

Now I can rename things and new folders that I create behave normally, but
legacy folders and files can't seem to be modified or deleted.

When I look, they are all flagged as Read Only, which would explain the
behavior....but when I change the read only status...it acts like it changes
it (progress bar etc)...but it doesn't change...
next time I open properties....it's read only again.

Would not any new user I create on the system also be part of "Everyone" and
thus I'm sort of stuck?

I feel like such a dunce.

Help is appreciated....

Thanks,
