You want to view the connection objects associated with a domain controller.
Open the Active Directory Sites and Services snap-in.
In the left pane, expand Sites, expand the site that contains the connection object you want to check, expand the Servers container, expand the server that contains the connection object, and click on the NTDS Settings object.
In the right pane, under the name column, it will display which connection objects are automatically generated (by the KCC) and which ones were manually generated.
> repadmin /showconn [<DomainControllerName>]
' This code lists the connection objects for a server ' ------ SCRIPT CONFIGURATION ------ strServer = "<ServerName>" ' e.g. dc01 strSite = "<SiteName>" ' e.g. MySite1 ' ------ END CONFIGURATION --------- set objRootDSE = GetObject("LDAP://RootDSE") set objNTDSCont = GetObject("LDAP://cn=NTDS Settings,cn=" & strServer & _ ",cn=servers,cn=" & strSite & ",cn=sites," & _ objRootDSE.Get("configurationNamingContext") ) objNTDSCont.Filter = Array("ntdsConnection") WScript.Echo "Connection objects for " & strSite & "\" & strServer for each objConn in objNTDSCont if objConn.Get("options") = 0 then Wscript.Echo " " & objConn.Get("cn") & " (MANUAL)" else Wscript.Echo " " & objConn.Get("cn") & " (AUTO)" end if next
Connection objects are used to replicate inbound changes to a domain controller. By viewing the connection objects for a server you can see what domain controllers it receives updates from. Connection objects are created automatically by the KCC, but can be created manually if necessary.
