NetScaler StoreFront Request Error

We started a Citrix XenDesktop 7.1 installation today and I was the person responsible for the Citrix NetScaler appliances.

In that case I had to setup two NetScaler VPX 10 appliances as a High Availability pair, load balance Storefront servers and DDCs and publish the applications and desktops using NetScaler Gateway.

I started by downloading the appropriate VM for Hyper-V, created a VM using the vhd (I could not import the VM in Hyper-V 2012 R2 because it was exported from older version of Hyper-V) and then created a clone for the second node.

I assigned IP addresses, uploaded license files and created an initial checkpoint of the VMs. I didn't update the firmware cause it was already at the latest version.

After that I created the servers for the StoreFront and DDCs and then the Service Groups and the Services on each group. I also load balanced the company's Active Directory servers for the authentication.

Then I created the virtual servers, the monitors and the LDAP authentication policy. The persons responsible for the StoreFront were able to configure their settings.

I was now ready to setup NetScaler Gateway with the above resources.

When I was done with the gateway I logged in and I got the message that my request could not be completed.

After installing brand new certificate and CA certificates on the NetScaler and StoreFront servers the error did not want to go away.

After taking a look at the StoreFront servers' log I found three errors with ids 10,8 and 3 stating that the server could not communicate with the authentication service on the NetScaler Gateway.

I then reviewed the NetScaler Gateway setup on StoreFront where I found out that the server could not resolve the NetScaler Gateway and Callback urls of the NG. I added an entry at the server's hosts file for the SNIP of the NetScaler and it worked!

After searching the web in order to verify my findings, I found this article that also has some pictures of the logs and the NetScaler Gateway setup wizard.

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
