Re: active directory will not start

Thanks for the help. Just to let you know that after a fruitless day
yesterday spinning my wheels trying different solutions, I pretty much did
exactly as you laid out and had everything back up and running in less than
an hour.

We also have a backup plan in place to make sure that we capture the AD sys
state on a regular basis in the future.

From DSRM change the registry key:

LanmanNT to ServerNT

On reboot you will be able to log on to the box in normal mode however
Active Directory will not start. From there you can promote the machine into
a fake domain, and then demote to completely remove Active Directory. Once
demoted you can then promote back up into your production domain. You must
go through the promotion to a fake domain otherwise Active Directory will
never be healthy.

or.... reformat :)

To all:

Ran checkdisk without problem on the balance of the drive. Don't know what
caused the corruption, could have been a number of things I suspect. Don't
have another DC or sys state to recover from, so the only answer is to
rebuild the DC, but here's the 25 cent question - how can you do that when
you cannot load active directory? Trying to remove AD when you can only get
into directory services restore mode isn't possible. Any thoughts???

You have two options

1. Rebuild DC, promote from another DC that is ok.
2. Rebuild DC, recover systemstate.

Other than that, you are done.

attempt fail with a JetEngine initialization error. We cannot even perform a
lossy repair!! Any help would be appreciated as we are desparate.
