Microsoft Office 2003 Registration Info After Uninstall

Recently I had to uninstall Microsoft Office 2003 from a computer and then install Microsoft Office 2007. The were no errors on both processes but when I scanned the computer with Spiceworks, it appeared  to have Office 2003 installed as well as 2007. That is because the registration info is not removed when the product is unistalled.

In order to remove that info, you have to delete the following key and it's subkeys:
HKLM\Software\Microsoft\Office\11.0\Registration

You should backup your registry before making any changes, or at least the keys you 're about to delete.

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, ...

Running Multiple NGINX Ingress Controllers in AKS

Image
In some of the previous articles of this blog, we went through the process of installing NGINX as the Ingress Controller in AKS clusters. Either for applications that should be available directly from the public internet, or for applications that should only be accessed from networks considered internal. In the majority of the cases, however, and given that an AKS cluster is an environment that is designed to host multiple applications and provide economy at scale, additional ingress controllers may be required. In this post, we're going to go through the process of deploying an additional NGINX ingress controller that is going to be used for internal applications. The below diagram depicts the desired outcome: The Angular application is published via the public NGINX through the Azure Load Balancer that has been assigned a public IP. The .NET app is published by a different set of NGINX pods that are deployed in a different namespace and their ingress controller service is connect
