Verify the Agent Connectivity to OMS Workspace

Now that we have configured our first agent to send data to the OMS workspace, how do we know that everything is working as it should?

The first place to check the status of the agent is the agent itself. Open the Control Panel and search for the Microsoft Monitoring Agent. If you switch to the Azure Log Analytics tab, the status of the agent is shown as following:


In case you need more details about the status of the agent and it's operations, events are written to the Operations Manager event log:


The last way to check the connectivity of an agent to the workspace is to query the heartbeat logs on the workspace itself. The agents send heartbeat messages to the workspace and those messages are available to query.


Here we see that the OMSGateway.lab.local computer has sent a heartbeat message on 2018-03-22 at 16:00 GTM. The IP address of the computer is also available along with the type and version of operating system and agent and other useful information.

There's a very cool solution for the OMS Portal that takes advantage of the heartbeat information and presents the status of the agents with some very nice diagrams.



The solution is called "Agent Health" and is available via the solutions gallery of the OMS portal. All you have to do is search for it and then add it to the portal.

Please note that the agent might need some to connect and the data to be available on the queries so don't loose your faith if it doesn't show up immediately.

Domain Controller Machine Password Reset

Image
On my lab environment, I've configured two Active Directory sites since most enterprises have offices in more that one places. My lab however is not running 24/7 and the domain controllers in the second site are rarely turned on in order to save resources. This leads to issues with the Active Directory replication such as the "The target principal name is incorrect" error when I execute:  repadmin /syncall /AdeP. To remedy the issue, we have to reset the machine password of the domain controller that has been offline. First off, we are going to stop and disable the Kerberos Key Distribution Center (kdc) service on the problematic domain controller, in our case DC4. There may be some tickets in the cache so we should also clear them using klist purge Now it's time to change the machine password of the domain controller using the command netdom resetpwd /s:dc3 /ud:lab\administrator /pd:* Replace the "lab\administrator" with an account on your

Configuring a Certificate on Exchange Receive Connector

Today's article is about configuring Exchange receive connectors with specific certificates. Out of the box, Exchange uses self signed certificates to provide TLS secured mail flow. This will definitely be an issue if you expose the SMTP protocol to client computers since they won't trust the certificate. In this article we are going to configure a certificate that was issued by a third part authority to the Client Frontend receive connector. We'll start with getting the thumbprint of the certificate using the Get-ExchangeCertificate cmdlet: [PS] C:\> Get-ExchangeCertificate Thumbprint                               Subject ----------                               ------- 241B864DC82C664FECBA18B8D54987AAFB65B4C2 CN=*.lab.com, ...

Managing Active Directory User Certificates using PowerShell

I first came across user certificates when I was working with email certificates a few years ago and I have to admit that I had trouble updating the certificates on the objects! Most organizations have a Microsoft Active Directory Certification Authority that issues the certificates used internally. When a certificate is issued to a user, the Microsoft Certificate Service saves the public key in Active Directory. The userCertificate attribute is a multi-valued attribute that contains the DER-encoded X509v3 certificates issued to the user. Although we rarely need to pay attention to this attribute, there are cases where we have to update it. To make things easier, I've written PowerShell functions to Get, Remove, Import and Export the certificates on that field. To get the list of certificates for an object, use the Get-ActiveDirectoryObjectCertificate function: PS C:\> Get-ActiveDirectoryObjectCertificate -UserPrincipalName cpolydorou@lab.local DistinguishedName
