Hi i wanna share some of my experience in the field.

Citrix Access Management tools have been renamed to Delivery Service Console.
Both consoles are available on the  XenApp5&6 DVD’s.
XenApp 5 requires a specific version of the console, please read belowed why.

The issue i have seen.

If you build an unattend setup of Citrix XenApp 5 for Windows Server 2008, and install the latest version of Delivery Service Console, then you would get an strange error in the console for the Farm.

I have identified the error and it seems that Access Management Console needs to be installed “FIRST” after the XenApp5 unattend job/setup.

When XenApp5 is installed then update the console to Delivery Service Console to the latest version to get the functionality.


Today, at Interop – Las Vegas, Citrix announced the release of NetScaler 9.2. It’s available for download on for all customers with a valid maintenance agreement. You’ll definitely want to check out all the cool new features that make NetScaler 9.2 the most cloud-ready application network platform for virtual datacenters. NetScaler 9.2 transforms infrastructure into a shared service, delivering cloud-scale performance and unmatched entity scaling for consolidation, supports easy management of app infrastructure, accelerates Web 2.0 and multimedia in the cloud and brings enterprise SLAs and security to the cloud. With over 75 new features, NetScaler 9.2 transforms the economics of app delivery and makes virtual datacenters a reality for both enterprises and service providers. Key new capabilities in NetScaler 9.2 include:

Deliver Cloud Economics and Scale

NetScaler provides unmatched performance, scalability, consolidation and flexibility. New NetScaler MPX solutions deliver the industry’s first 50 Gbps appliance in an energy and space efficient 2U form factor and introduce unparalleled elasticity into the physical network with “Pay-as-You-Grow” – allowing customers to scale from 20 Gbps, 35Gbps and 50Gbps on the same physical appliance without the need for expensive forklift upgrades.

In addition, to support the rapid global adoption of IPv6 while simultaneously becoming the consolidation backbone for very large Service Providers, IPv6 performance and NetScaler’s capacity to support cloud-scale configurations has increased dramatically with NetScaler 9.2. IPv6 performance increases by 50% while IPv6-IPv6 HTTP requests per second increase by 4X, enabling organizations to standardize on IPv6 for better scale, quality and performance. NetScaler’s capacity to support thousands of tenants and their associated configuration services, entities and applications has increased by 2X-7X driving network consolidation and economies of scale and simplifying management.

Drive Next Generation Multi-Tenancy

Shared services is a key attribute of a virtualized datacenter. New Network Aware Policies and Policy-Based Routing features enable an application aware multi-tenant network by segmenting traffic by vLAN or other L2-L4 parameters. Additionally, new NetScaler AppExpert Template and Visualizer features simplify management, migration, monitoring and synchronization of application delivery policies. Specifically, templates from existing configurations can be created for easy import/export into test and dev environments by abstracting management complexity and allowing creation of environment specific configurations.

AppExpert Network Visualizer provides a completely new way to look at how NetScaler is connected to your network. This is a graphical and fully interactive view of your network. You can configure network components like interfaces and vLANs by clicking on them directly from the configuration map. It’s also possible to add channels, view properties of configured network-related entities, and pull down statistics and counters for a particular interface or vLAN.

Global Server Load Balancing (GSLB), by it’s nature, has several layers of configuration in the feature. Once you start adding a few sites and remote services, the configuration can start to become a little involved. The GSLB Visualiser is the perfect way to graphically represent your GSLB configuration. It will organize it intelligently by the domain names you are running on GSLB, and show you exactly which systems are up / down, and allow you to get statistics on each entity.

Bring Enterprise SLAs and Security to the Virtual Datacenter

New Active-Active capabilities provide greater high-availability and network utilization to ensure enterprise SLAs are met. In addition, new web services and XML security capabilities protect applications from attacks and help enterprises comply with security regulations. These include: cross-site request forgery protection, XML attachment checks, entity expansion attack protection, SOAP fault filtering, WSDL scanning protection and XPath injection protection.

To support the transition of various application workloads to off-premise cloud deployments while providing a seamless user experience, NetScaler 9.2 has various enhancements to its Global Load Balancing suite of features including spillover of user traffic which is a critical element to drive Cloud Burst scenarios.

Optimize delivery of Video, Web 2.0 and Multimedia

NetScaler 9.2 introduces 64-bit shared-memory caching.  High-end NetScaler MPX platforms can provide up to 24GB of memory cache capacity, to cache large video files at the service provider edge, or to offload back end servers. Delivery of Web 2.0 applications are optimized with new Fast XML XPath support, which provides deep XML payload inspection and enables high-performance business logic routing.

Citrix released the latest version of XenDesktop PoC toolkit 1.1

The XenDesktop Quick PoC Kit has been created for being used as a tool for Proof of Concepts and is intended for validating desktop delivery with XenDesktop within a short time period. It provides a quick and simple setup of the required infrastructure components and can be used for Proof of Concepts that run either in an isolated environment or can even be integrated into any of the customers’ environment. The average setup time varies between 2-4 hours. The kit consists of a set of documentation guiding through the setup and the required pre-built virtual machines. The updated version 1.1 contains a new Windows 7 Enterprise vDisk and a 25-user XenDesktop Platinum Edition evaluation license. The Branch Repeater PoC toolkit has also been updated to onclude XenDesktop and XenApp in its deployemtn scenario

The Citrix Branch Repeater (PoC) Toolkit enables you to configure the most widely used Branch Repeater Family deployment scenarios based on common customer requirements, including integration with XenApp and XenDesktop environments. The PoC Toolkit takes the reader through a guided process of planning, configuring, validating, and summarizing a PoC based on demonstrating TCP-based protocol acceleration with Branch Repeater. The deployment scenario in the toolkit is based on a common infrastructure environment that can be substituted for an actual customer environment.

Ruben Spruijt, Jeroen van de Kamp have updated the famous “PROJECT VRC: Phase II” document.

Whitepaper contains new tests, comparing TS workloads on VMware vSphere 4.0, Citrix XenServer 5.5 and Microsoft Hyper-V R2:

The main updated findings of “Project VRC Phase II version 2.0” whitepaper are: 
• Considerable vSphere performance increase with VMware vSphere patch
• Update on best practices and recommended configuration
• Investigated: performance impact ASLR
