Big Business Goals? Which KPIs Will Help You

The most successful MSPs rely on metrics – known as key performance indicators (KPIs) – for making informed decisions that help their businesses thrive, rather than just survive. This eBook provides an overview of the most important KPIs used by top MSPs.

what you did is catastrophic... very bad... there's not any easy list of steps to follow, only the hard way (the link he posted above), and the harder way (blow everything up and recreate it all)

...maybe you could call microsoft product support, for a $250 phone call they should take over your screen and fix it for you

Please phone a Microsoft support professional at (800) 936-4900

A non-authoritative restore means that the objects you restore will be overwritten during the next replication cycle.  What you need to do is mark the OU as authoritative.

Guy has a good step by step here  http://www.computerperformance.co.uk/w2k3/utilities/windows_authoritative_restore.htm

I also helped with a question last year to help with an authoritative restore

IT-MAN-2010,

Your not going to find a 10 step guide.  It's fairly involved. If your not willing to read even a KB you should probably just call MS.  $250 is cheap support.
