I recently attempted to update to SP4 on my Windows 2000
installation. Upon the required reboot, I was presented
with the dreaded BSD and a message stating that my boot
device was inaccessible. (I have an 80GB IDE drive that
uses EZ-BIOS overlay software).

I was able to recover by using the ERD and, once I was
able to log in again, I uninstalled SP4. However, now my
administrator account seems to have lost it's
administrator privileges. I am unable to add or remove
hardware or install some software. I get the message
saying that I should log in as administrator (I am).

How do I get my administrator privileges back?

I thought I would post an update on this. I found this KB
article mentioned in another posting. I tried it and it
successfully restored my Administrator privileges. :-)

Hopefully, this helps out someone else.
