Resyncing AD

Hi, I have a situation. I just got customer who had deployed 2 2K3 AD and
had it sync with each other in the local office. however, they split the
network between 2 sites and have been making changes on both sites. thus now
both site have different database. this has been going on for a while and
they did not connect the 2 sites together, thus the AD is not sync.

Question: If they connect the network together now and tried to sync the 2
AD, will the different changes made on both AD be sync to each other thus
have a single database again? Thanks.

For how long have those two domain controllers been seperated?

Hello Gilbert,

If you are under the tombstone lifetime you can be happy that they can replicate
again, maybe with some conflicts based on the different changes on both sites.
In 2000/2003 or upgraded 2003 SP1 or R2 the default is 60 days, 180 days
is only if the forest was created with SP1 installed before promoting or
with CD1 from R2.

You will see if lingering objects exists with Event ID's 1388, 1988, 2042
for example:

Harlo, I would imagine that its been about 3 months... the OS is W2K3 R2...
reading from the other post, it seems like there would be trouble... if
they tried to sync, what could be the likely outcome? changes on one site
disappeared?

Thanks.
Gilbert

what do you mean with:
"deployed 2 2K3 AD"
"had it sync with each other in the local office"

multiple forests?
multiple domains?
one domain but split up? (if yes, for how long)

what's the name of the "ADs"

not enough details to answer your question
