I remember when Windows NT 4.0 Terminal Server edition was released, and the integrated capability of having more than one user access a server at a time was born. Sure, Citrix had created this already with WinFrame on Windows NT 3.51, but Windows NT 4.0 Terminal Server edition brought the functionality to the native operating system. We take this for granted now, with every administrator of a Windows server environment heavily relying on RDP for their day-to-day jobs. But it was an exciting time. But the... read more.

To follow up on my previous blog about the Cloud First world we live in, I thought it would be helpful to highlight an area where the cloud offers a great AND low cost solution for Citrix disaster recovery. The costs of having workloads in the cloud are typically the largest obstacle for our customers to start the journey to the cloud.

Splunk allows the transformation of dashboards into forms, which present controls for users to enter search criteria. This allows you to have text boxes, pulldown lists, checkboxes, radio buttons, and other controls at the top of the form. The user’s selections from these input controls are stored in tokens that you can use in your queries or to control various aspects of the form. You can also add these input controls to specific panels on your form, not just at the top of the page. This makes it... read more.

When extracting fields from events in Splunk, typically each field has a single value. For instance, in a firewall packet event there is a src_ip, src_port, dest_ip, dest_port, action, etc., each with a single value. But there are occasionally fields which have more than one value. One common field type that often has multiple values is an e-mail address field, such as from or to. Splunk deals with these values by allowing fields to hold multiple values, which it refers to as simply a “multivalue fiel... read more.

Overview Citrix acquired Unidesk in early 2017, and quickly integrated the App Layering technology into the stack.

In Citrix XenApp and XenDesktop 7.18, a new feature was introduced to help identify issues from user locations to the Citrix environment hosting the applications and desktops. This feature, Application Probing, has a few requirements, but is not too difficult to set up and can provide immediate value. Application Probing requires the following: Citrix XenApp / XenDesktop 7.18 or newer runni... read more.

Global Server Load Balancing (GSLB) is a feature of NetScaler that provides for disaster recovery and continuous availability of applications when there are points of failure in a wide area network (WAN). GSLB can balance application loads across data centers by directing client requests to the closest or best-performing data center, or in the case of an outage, any surviving data center. In a typical GSLB deployment, proximity-based load balancing methods are used to determine the location of the client a... read more.

Part 1: Adding the Timeline Visualization Why a Timeline? One important metric when delivering user desktops is the amount of time the user has to wait for the desktop to launch. It’s hard to ensure user acceptance of the delivered environment if they find it slow before their desktop even becomes available. Various processes run to build up the user environment from many configuration layers, including group policies retrieved from busy domain controllers, policies from desktop delivery software li... read more.

The benefits of patching in a timely manner include feature enhancements, bug fixes, and of course security updates. But for many of our customers, patching is time-consuming and resource-intensive, and gets in the way of IT teams focusing on more strategic and tactical matters. As a result, patches aren’t maint... read more.
