Event ID: 1311

[Milt]

Can anybody please help with this error message?

The Directory Service consistency checker has determined that either (a)
there
is not enough physical connectivity published via the Active Directory Sites
and
Services Manager to create a spanning tree connecting all the sites
containing
the Partition CN=Configuration,DC=DOMAIN, or (b) replication cannot be
performed with one or more critical servers in order for changes to
propagate across all sites (most often
due to the servers being unreachable).
For (a), please use the Active Directory Sites and Services Manager to do
one
of the following:
1. Publish sufficient site connectivity information such that the system can
infer a route by which this Partition can reach this site. This option is
preferred.
2. Add an ntdsConnection object to a Domain Controller that contains the
Partition CN=Configuration,DC=DOMAIN in this site from a Domain Controller
that contains the same
Partition in another site.
For (b), please see previous events logged by the NTDS KCC source that
identify the servers that could not be contacted.

Hello Milt,

This is usually due to the fact that "Site link bridging" is enabled by
default and the network is not fully routed meaning that we cannot contact
the remote site due
to the network design. To resolve this issue you must disable "Site link
bridging" by peforming the steps in the articles listed below:

Other things to check
===============
1. Make sure the Intersite Messaging Service is started and set to
automatic.

2. Point the problem DC to another DNS server and run ipconfig
/registerdns, you should also restart netlogon.
