Check the followings: Host file DNS forwarders Make sure conditional forwarders are correct if there are any DNS search order in the network configuration properties tab
For troubleshooting, use nslookup and its "set debug = 9" feature, I did not remember the exact style now, though In the worst case, compare all these related configurations side by side with the fine-working DC. Good luck, Rami From: [email protected] [mailto:[email protected]] On Behalf Of CSSU NetAdmin Sent: Monday, March 10, 2014 5:45 AM To: [email protected] Subject: [NTSysADM] Active Directory DC replication issue We have an Win2008R2 forest. There are two parent DC's and two child DC's. One of the child DC's is not replicating correctly. It seems to be OK with its child partner but it doesn't not sync with either of the parent DC's. The problem seems to be with DNS. When we run - REPADMIN /SHOWREPL * /CSV >showrepl.csv - on the box, it returns an LDAP error 81 (Server Down) Win32 Err 58 error message. Interestingly, when we ping a parent DC from the DC with the issue, it returns an outside IP address not associated with us at all. It pings its sibling fine. DNS looks like it is configured OK. The children point to each other and the parents point to each other and the other three can ping all of the DC's correctly. Any ideas for this issue would be appreciated.
