The logs don't really tell much because they are so full they are
only
holding 2 day's worth of data. I keep getting repeats of the
following
Events in my Directory Services Event Log:
Event ID:
1865
"The Knowledge Consistency Checker (KCC) was unable to form a
complete
spanning tree network topology. As a result, the following list of
sites
cannot be reached from the local site..."
Event ID: 1925
"The
attempt to establish a replication link for the following writable
directory
partition failed. ..."
--
Event ID: 1566
"All domain controllers in the
following site that can replicate the
directory partition over this transport
are currently unavailable...."
--
Event ID 1311:
"The Knowledge
Consistency Checker (KCC) has detected problems with the
following directory
partition.
Directory
partition:
CN=Configuration,DC=mydc,DC=mydomain,DC=edu
There is
insufficient site connectivity information in Active Directory
Sites and
Services for the KCC to create a spanning tree replication
topology. Or, one
or more domain controllers with this directory
partition
are unable to
replicate the directory partition information. This is
probably due to
inaccessible domain controllers.
--
All of the Domain controllers are
still allowing users to log on, which
is
why I'm limping through the last
week and a half of the Quarter. I
believe
the problem occurred because I
restored my PDC from a ghost image of the
day
before at the end of march
because of a problem the server had with a
windows update that I couldn't get
rid of. And ever since replication
seems
to have been working but my
guess is it's only been working 1 direction.
My
PDC receives updates from
another DC in the site and that has worked.
But
replication from my PDC
back to that DC has not. Although this last
week
replication has
just given up all together.
Thanks,

Does the PDC FSMO or the other DCs have any
events with errors can
possibly
tell more about this
issue?

I've talked about this a little before, but I dug in a littler
further
and
found more info.
I have 4 domain controllers in 1
domain.
When I'm on one of the 3 DC's that is not the PDC and I try to
connect
to
the PDC it tells me I'm not authorized. I get this when
trying to
connect
to the PDC's AD users and computers, DNS, or even a file
share. I can
however connect to any of these services using the IP
address. This is
strange because all DC's can ping each other and resolve the
IP
addresses
from the names just fine and I don't seem to be having any
DNS issues.
The
3 DC's (not the PDC) can connect to each other just
fine.
I'm pretty sure I'm going to need to remove 1 or more of the DC's
from
the
domain and re-introduce them. I'm just trying to figure out
if I should
remove the PDC or remove the other 3
DCs.
Thanks,
