Verify what domain controller

Distributed File Service Replication tests examine DFSR Event log warnings over the last 24 hours to verify that the replication system is working correctly. This is for Windows Server and later. Other account-related tests include a verification that the account of the domain controller can access Active Directory and that it is marked as a Domain Controller account, that all flags on the account are correct and that it has the correct server reference. These account tests also offer repair options in the commands that run the checks.

Object replication verification checks a small number of objects and attributes on several domain controllers to ensure that they have been replicated. The test will also show the last update date and time of each value on each instance. Note that this replication is for the data within the domain controller. Replication checks return data on recent replication attempts, showing statuses and times of each event.

It particularly focuses on whether any replication took more than 12 hours and whether any domain controller has replication disabled. Event log tests ensure that Windows Event logs related to Active Directory are being preserved. These print all related log messages from the last 60 minutes. Replication topology checks look at whether inter and intra-site replication is possible for a specific domain controller by exploring the settings of all upstream and downstream replication partners.

How to run DCDiag tests The dcdiag. DCDiag options DCDiag options go after the command and an optional identifier for a remote domain controller. Only show error messages. Display detailed information on each test.

Running specific tests with DCDiag dcdiag. DnsForwarders Checks the configuration of forwarders plus the DnsBasic tests. DnsDelegation Checks for proper delegations plus the DnsBasic tests.

I would just use this command..

Ed Grauel Jun 18, at pm. BMoore - thank you! There seem to be a few ways to skin this cat. Hi, Thanks for posting here! Following command for your reference: Nltest can test and reset the secure channel that the NetLogon service establishes between clients and the domain controller that logs them on.

MAK key installation Unlock my machine in background - command. This command forces the KCC Knowledge Consistency Checker on targeted domain controller s to immediately recalculate its inbound replication topology.

It checks and creates the connections between the Domain Controllers. By default KCC runs in the background every 15 minutes to check if a new connection has been established between DCs.

This command forces the replication of the specified directory partition to the destination domain controller from the source DC. Intra-site replication : With the exception of critical directory updates that are replicated immediately, the source DC updates changes to its closest replication partner every 15 seconds.
