To enable the detailed diagnosis capability of this test for a particular server, choose the On option. To disable the capability, click on the Off option. If the health check returns a positive result, the value of this measure will be Pass.
If not, the value of this measure will be Fail. The numeric values that correspond to these measure values have been discussed in the table below:. However, in the graph of this measure, the same will be represented using the numeric equivalents only. If the measure reports the value Fail, you can use the detailed diagnosis of this measure to know the reason for the failure and the domain controller where the failure occurred.
This eases the pain involved in troubleshooting problem conditions. Privacy Policy Terms of Use. I consoled my self that you can always get the information by running the full test and just reading the parts that are of interest. This utility will also guide you through troubleshooting; the dashboard will indicate whether the root cause is a broken link, faulty equipment or resource overload.
Its second best feature is the ability to monitor the health of individual VMware virtual machines. If you are interested in troubleshooting, and creating network maps, then I recommend that you give this Network Performance Monitor a try.
NTM will produce a neat diagram of your network topology. DCDiag is a simple yet very powerful tool to check and diagnose domain controllers. I highly recommend that you become familiar with this tool and run it in your environment from time to time.
You can select which DCs to test, which tests to run, and get emailed reports on test results. Click here to learn more. Here tare the commands I like to run. It will run all tests, displays all the details and outputs it to a file. Great article on using DCDiag and providing an example of what a normal server result would look like. I have not run it but it appears to be supported. What is Dcdiag Dcdiag is a Microsoft Windows command line utility that can analyze the state of domain controllers in a forest or enterprise.
I counted a total of 30 different tests, and some tests had multiple tests. So what does Dcdiag actually do? This argument checks the ability to create a replication link between a real or potential source domain controller SourceDomainController and the local domain controller.
CutoffServers Checks for any server that is not receiving replications because its partners are not running. You can run the tests individually or together. The tests include the following parameters:.
Confirms that essential services are running and available, necessary resource records are registered, and domain and root zones are present. Determines whether recursion is enabled and that any configured forwarders or root hints are functioning. Checks that the Active Directory domain zone is configured to do secure dynamic updates and register a test record. AD DS displays text, such as naming context names and server names, which contains international or Unicode characters correctly only if you have installed appropriate fonts and language support on the test computer.
DcPromo Tests the existing DNS infrastructure for any computer that you want to promote to be a domain controller. This parameter reports whether any modifications to the existing DNS infrastructure are required. With the exception of the DcPromo and RegisterInDNS tests, you must promote computers to be domain controllers before you run tests on them. Identify servers that returned "warn" or "fail" status for any subtest in the summary table. Repeat steps 1 through 6 as required until all failures are understood and reconciled.
Dcdiag takes a conservative approach by identifying DNS client or DNS server configurations that may be problematic, do not conform to best practice configurations, or that dcdiag cannot fully validate.
Therefore, the summary and detailed sections of dcdiag may report warnings for DNS configurations that are currently functional.
Administrators should investigate and validate such configurations when identified by dcdiag. The tables below contain the configurations that can trigger dcdiag to report warnings or errors for each of the DNS subtests.
Every domain controller should register a host A resource record. Make sure that host A records are registered on all the DNS servers that the client is pointing to. Forwarders configured on the DNS server have an invalid IP address or are not a DNS server, or name resolution is not working that is, cannot resolve forest root domain SRV record if it is a non-root domain domain controller.
Error: Both root hints and forwarders are not configured. Please configure either forwarders or root hints. Make sure that either forwarders or root hints are configured on the DNS server unless it hosts a root zone. Status field will tell you the status of the server.
