SYMPTOMS
The Directory Service log on your server that is running Microsoft Windows 2000 Server logs Event ID 1128 and Event ID 1129 every 15 minutes.

Event ID 1128 contains information that is similar to the following:

3/25/2003 8:19:19 AM 4 1 1128 NTDS KCC N/A MMACCT-DC-04 A replication connection

from CN=NTDS

Settings,CN=MMACCT-DC-24,CN=Servers,CN=BocaFl-RSO01-Site,CN=Sites,CN=Configuration,DC=root,

DC=mds to CN=NTDS

Settings,CN=MMACCT-DC-04,CN=Servers,CN=WAN-01,CN=Sites,CN=Configuration,DC=root,

DC=mds was created.Event ID 1129 contains information that is similar to the following:3/25/2003 8:19:19 AM 4 1 1129 NTDS KCC N/A MMACCT-DC-04 The replication connection

from CN=NTDS

Settings,CN=MMACCT-DC-24,CN=Servers,CN=BocaFl-RSO01-Site,CN=Sites,CN=Configuration,DC=root,

DC=mds to CN=NTDS

Settings,CN=MMACCT-DC-04,CN=Servers,CN=WAN-01,CN=Sites,CN=Configuration,DC=root,

DC=mds was deleted to improve the replication load of the system



CAUSE
This problem occurs because the Knowledge Consistency Checker (KCC) detects that a connection in a site is incorrect, and then it generates a new connection (a duplicate). But soon after, the KCC deletes the new connection because it does not permit duplicates. This behavior continues without resolution.

The KCC deletes the new connection because the m_timeCreated property of the connection is set to 0 instead of to the current time. Therefore, the new connection appears older than the incorrect connection, and the new connection is deleted.



WORKAROUND
To work around this problem, delete all connections that are referenced in the Event IDs to force the KCC to create new correct connections, and then permit the KCC to re-create these connections. To delete connections, follow these steps:
 * 1) Click Start, point to Programs, point to Administrative Tools, and then click Active Directory Sites and Services.
 * 2) Click Sites, and in the right pane, double-click the site name that is listed in the Event ID.
 * 3) Double-click Servers, and then double-click the domain name.
 * 4) Double-click NTDS Settings, right-click each connection, and then click Delete.



STATUS
This problem is scheduled to be fixed in Windows 2000 Service Pack 5 (SP5).
