KCC Error on 1/2 of DCs at Site

-

i have small environment 3 sites connected single site link.

site 1 has 2 domain controllers

site 2 has 1 domain controller

site 3 has 1 domain controller

all dcs 2008 r2.  dfl , ffl 2008r2.  all dcs gcs , dns servers.

what i'm seeing 2 warning events , 1 error event every 15 minutes on 1 of domain controllers @ site 1 - not on of other domain controllers - including secondary dc @ site 1.

here's i'm seeing:

event id:  1865 -- kcc unable form complete spanning tree network topology...

event id:  1566 -- directory servers in following site can replicate directory partition on transport unavailable.  (site information shown , points site 3)

event id:  1311 --  the kcc has detected problems following directory partition.  cn=configuration,dc=mydomain,dc=local

there insufficient site connectivity information kcc create spanning tree topology or 1 or more directory servers directory partition unable replicate...

i have run dcdiag /test:connectivity on dcs no issues.  again, 1 of 2 dcs @ site 1 seeing these errors, other dcs fine.

i have followed steps here:  http://social.technet.microsoft.com/wiki/contents/articles/1375.event-id-1311-microsoft-windows-activedirectory-domainservice.aspx  verify settings in ad sites , services

why 1 of dcs @ site experience issue?  what can resolve problem?

hello,

please assure no ports listed in http://technet.microsoft.com/en-us/library/dd772723(ws.10).aspx closed , dcs use domain internal dns servers on nic.

an unedited ipconfig /all each dc verify settings.

for event id 1865 see http://technet.microsoft.com/en-us/library/cc756648(v=ws.10).aspx and see similar thread http://social.technet.microsoft.com/forums/windowsserver/en-us/9a65c9f3-9f5e-4284-ad57-b838680cf0c5/ad-replication-issues-event-ids-1865-1311-1566

is of dcs created image not prepared sysprep or there restore on 1 of dcs not supported backup image/clone/snapshot?
