I have two Domain Controller in my envorinment, Primary Domain Controller is Windows Server 2003 based and Additional domain controller is Windows Server 2008 based. When I Installed New 2008 ADC and after some time, when I check with repadmin /showreps found the error.... DsReplicaGetInfo() failed with status 8453 (0x2105):Replication access was denied. I really worried about Solutions: [ DsReplicaGetInfo failed with status 8453 ]
