Ace, are you around?

Hi Ace.

I need you in the Active Directory forum if you are around. I have a big
problem with NDTS.dit being corrupted. Help?

I am not Ace but....

You should probably just do a DC program if you have another DC still
online.
(Transfer any roles and GC to the other DC first if possible.)

Then do another DCpromo to get a NEW copy of the AD.

If you don't have another DC, restore system state from backups.

After than you are faced with running "Semantic Database Analysis" which is
a REALLY
BAD idea if you have any other choices so you really should have a backup.

I need you in the Active Directory forum if you are around. I have a big
problem with NDTS.dit being corrupted. Help?

How do you know that NTDS.dit is corrupt?

Hi Herb,
I am personally thanking all who helped, I appreciate it more than I can say.
heres how it turned out: (and yes semantic database analysis was involved)

After 3 1/2 hours of actual phone time (after 2 hours waiting = 5 1/2 hours
with a phone in my ear) we got it back as far as I can tell. It came down to
running the ntdsutil and then eseutil in a certain sequence. and it recovered.
The same for the exchange database. a specific sequence of eseutil and isinteg
switches, that is not outlined specifically enough in any single KB article
which was found in a message (they called it an object I think, something that
may someday become a KB article?) the pss guy walked me through it and it did
everything it said it would and it is now running again. I had all the pieces
but the ordering was critical.
I don't know how much I lost because it was 3am this morning that I left it with
the disk just churning away (Exchange trying to to catch up perhaps?) But when I
checked my mail today I might have lost the day it crashed but thats all.

Next I move the stuff off this thing and rebuild after a graceful demotion. But
that will wait a few days, I gotta get some sleep.
Thank you all for so much help!

Glad you are meeting with success.

The solution actually jibes with documentation that says (words to the
effect),
"Never run semantic database analysis unless you are talking to PSS."

Well, thats true enough. The big breakthrough came from running esetutl (not
eseutil) with a list of command line switches that almost went to the end of
the screen. All other tests and fixes said "database inconsistent" and
wouldn't do anything. But that was the magic bullet.
Well worth the price of admission.
Thank you again for jumping in to this. I am overwhelmed with the support
given here.
I someday will learn enough to give back a small percentage of what I
receive.

Sounds like you went thru alot. I guess PSS was the best bet in this case.

I would love to see the report of all the things you actually did in the
right order....

 

[mmac]

I sent that to Ace in the AD group. If you can't find it let me know and
I'll send it to you too.
