LDAP Error 81

    Question

  • Our environment has a root and several child domains running W2K8 SP2.  For 1.5 days a server was down that has a replication partner for the same child domain in a difference site.  After network services were restored, I ran KCC * from the root.  All were successful except the down child domain.  There I get the error:  '[d:\longhorn\ds\ds\src\util\repadmin\repldap.c, 1415] LDAP error 81 (Server Down) Win32 Err 58.'

    All of the servers are online now.  Would I still need to perform a metadata clean up?  Or, will AD clean itself?  If I need to clean up AD I am not certain of the steps involved with the clean up.

    Thanks, Jesse

  • Hello,

    if a DC was down for that short period of time you shouldn't have any problem after reconnection, it should automatically start replicating. Before doing anything like metadata cleanup please upload the following files, so we can get an overview:

    ipconfig /all >c:\ipconfig.txt [from each DC/DNS Server]
    dcdiag /v /c /d /e /s:dcname >c:\dcdiag.txt
    repadmin /showrepl dc* /verbose /all /intersite >c:\repl.txt  ["dc* is a place holder for the starting name of the DCs if they all begin the same (if more then one DC exists)]
    dnslint /ad /s "DCipaddress" (http://support.microsoft.com/kb/321045)


    As the output will become large, DON'T post them into the thread, please use Windows Sky Drive (skydrive.live.com) [with open access!] and add the link from it here. Also the /e in dcdiag scans the complete forest, so better run it on COB.

  • Hi,

    you have to do a metadata cleanup ONLY when you want to remove a failed DomainController which can´t be removed with a regular demotion of the DC.

    When I unterstand your post correctly, then your DC was only down for a short period of time.

    Please check your replication status

    - use dcdiag /v /c /d /e

    - repadmin /replsummary *

    - repadmin /showrepl *

     

    Look for errors in the results and please post errors when you find some.

     

    Martin

  • Metadata cleanup is performed to remove the DC & its references from the domain when either DC is crashed or permanently offline, which doesn't look to be the case from your post. Since, DC was down for 1.5 days, reconnecting should make it work as this is not the big deal.

    Make sure proper DNS is specified in child domain DC & all the DC related (DNS/FRS/KDC/Netlogon)services are working.

    How many DC's are there in the child domain? Could you post relevant error message from the event log.

    I have outlined the metadata cleanup explanation & steps, but until DC is crashed or permanently offline metadata cleanup is not required.
