Event ID: 1311/1566 errors

[C Hall]

Good morning,

I've been seeing 1311 & 1566 errors in Event Viewer. The errors are
intermittent and at first I ignored them, thinking that the wan link may
have gone down, but looking at the times the errors are occuring, that
couldn't be the reason. When I setup the two DCs (two physical locations), I
verified that the install was correct per KB 298143. Sites have been
properly created and the default site link contains both sites. I did have
one site set as the Preferred Bridgehead server, but removed that based on a
suggestion from "Troubleshooting Active Directory Replication Problems" from
the Active Directory Operations Guide. These errors cycle through about
every 3 to 6 days and last for 2 1/2 to 4 hours. They happen at different
times of the day. Both netdiag and dcdiag run clean on both DCs. The zones
for DNS are Active Directory Integrated zones, with Allow Dynamic Updates
set to yes. I believe I've heard that if you're having these errors, change
the zones to Standard Primary.


If anyone has any other suggestions, I'd appreciate it.

What you need to do is look at the DNS servers that are used by each server.
If they are using different DNS servers, then you need to create a secondary
zone for each of the zones hosted by each DNS server on the other DNS
server. Then let them do a zone transfer and this should go away. You also
may need to create a LMHOST file during testing to get this to work as well.
I had a case like this and when we created the secondary zones, and used the
LMHOST file, the event 1311 went away and we completed the Exchange
migration...

Both server point to the Forest root server as the domain name server. I
have forwarding enabled so clients can resolve internet domain names. I'm
currently using AD-Integrated zones, but am going to change them to Standard
Primary zones.

Ozone,
I've changed the zones to standard primary/secondary. You mentioned creating
a LMHOST file below, did you just put in the servers or all records.
