Hi, I'm having troubles with windows server 2008. This problem occured suddenly, everything worked fine but now the 2 domain controllers won't replicate anymore and I'm getting the error: Event ID 1001: (every 5 minutes) Security policy cannot be propagated. Cannot access the template. Error code = 3. \\Domain\sysvol\vyncke.voh\Policies\{31B2F340-016D-11D2-945F-00C04FB984F9}\Machine\Microsoft\Windows NT\SecEdit\GptTmpl.inf. I'm also having errors in the DFS Replication events: (event id 1202) The DFS Replication service failed to contact domain controller to access configuration information. Replication is stopped. The service will try again during the next configuration polling cycle, which will occur in 60 minutes. This event can be caused by TCP/IP connectivity, firewall, Active Directory Domain Services, or DNS issues. Additional Information: Error: 160 (One or more arguments are not correct.) AND in the Directory service events: (event id 1863) This is the replication status for the following directory partition on this directory server. Directory partition: DC=ForestDnsZones,DC=Domain,DC=voh This directory server has not received replication information from a number of directory servers within the configured latency interval. Latency Interval (Hours): 24 Number of directory servers in all sites: 1 Number of directory servers in this site: 1 The latency interval can be modified with the following registry key. Registry Key: HKLM\System\CurrentControlSet\Services\NTDS\Parameters\Replicator latency error interval (hours) To identify the directory servers by name, use the dcdiag.exe tool. You can also use the support tool repadmin.exe to display the replication latencies of the directory servers. The command is "repadmin /showvector /latency <partition-dn>".

This can have multiple causes. are there any other events logged? For exampel take a look at followong MS KB's: Event ID 1000, 1001 is logged every five minutes in the Application event log: a group policy corruption error Error Messages Every 5 Minutes Report Events 1000, 1001, and 13508, Citing Replication Trouble: a time synchronisation failure event 1863 points out the local domain controller has not recently received replication information from several domain controllers (intersite). This is a result, not a cause. event 1202 is probably more a cause than a result: Failing DFS replication can be the cause, or hte result from the issue. use this link to troubleshoot this. To be very short: check all connectivity and authentication between the DC's! MCP/MCSA/MCTS/MCITP

Hello, please follow this ones to troubleshoot replication problems: http://technet.microsoft.com/en-us/library/cc949120(WS.10).aspx For additional help please use Windows Sky drive to upload the following output files: dcdiag /v /c /d /e /s:dcname >c:\dcdiag.txt repadmin /showrepl dc* /verbose /all /intersite >c:\repl.txt (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. Also the dcdiag scans the complete forest, so better run it on COB.Best regards Meinolf Weber Disclaimer: This posting is provided "AS IS" with no warranties or guarantees , and confers no rights.
