With the release of Citrix Receiver 4.x, Citrix has done away with the Program Neighborhood Agent (PNAgent), and with it, the ability to automate the creation of shortcuts to published applications on the user’s desktop. A customer recently asked me for a solution to this problem and I was able to get around it using the method below. When using Receiver 4.x, users are able to add published applications as favorites. When a user adds an application as a favorite, a Citrix-compiled .exe gets created and p... read more.

Citrix was able to converge the management and infrastructure for XenApp and XenDesktop into one product with the release of XenDesktop 7. There are many benefits to having a single architecture and shared infrastructure between the two products. Not advertised, but I believe the most important benefit, is a common feature set and single development thread for both products. This will drive faster innovation and improve support. The product was XenDesktop 7, and new terminology for the supported workloads c... read more.

There are many monitoring solutions on the market, some with specific focus for Citrix environments that tout an "end-to-end" view. But, I've yet to see a single dashboard that shows a user's connection through the NetScaler, Citrix XD/XA, and backend connections to SQL, storage, and other critical components. Splunk can capture data from all of these sources, and index it to your heart's content. But, out of the box you get individual dashboards without the zoomed out view we all crave. That is where Go... read more.

The NetScaler SDX platform is a combination of high performance hardware with a hypervisor tuned to take advantage of it. The solution offers direct mapping of specific components to virtual NetScalers, such as CPU, Memory, SSL cores, and NICs via SR-IOV. But Citrix teased us a while back that the SDX platform may also support workloads other than NetScalers. Citrix has now delivered, working with some third party vendors to offer new workloads on the SDX platform. These are the available products: We... read more.

Now that Windows 8 is officially on the store shelves no doubt users will be scouring the Windows Store looking for Windows 8 applications to play with. One app users may find is the Lync application. Once installed, excited users will enter their credentials and expect to connect to Lync just as they do with their standard desktop client or Lync mobile client. Unfortunately, many users will be disappointed when they receive a “Cannot connect to server” error message. This will create a mad frenzy among use... read more.

If you are involved in an InterOrg Exchange migration, you are going to have to migrate your Public Folder infrastructure from the source Exchange organization to the destination organization. Exchange does not offer a native tool to do this. This means you will either have to invest in a third-party utility like the Quest Exchange migration tool or use a free tool from Microsoft called the InterOrg Replication tool (IORepl). As you might expect, the third-party tools are far superior to IORepl, but are als... read more.

Lately, we’ve seen a lot of activity at Gotham clients regarding increasing the functionality their SSL VPN. Gotham has installed a lot of this technology and I was thinking about the early days of SSL VPN. When SSL VPNs first came out, Gotham was one of the first movers in evangelizing what we thought was a great way to simplify access for individual users. During the education process we would eventually find ourselves in the office of whoever was running the traditional IPSEC VPN that was currently in... read more.

I recently had the opportunity to deploy Provisioning Services 6.1 to upgrade an existing client from 5.6. As there was no possibility of downtime, we decided to go with a parallel update; taking a copy of the existing vDisk and reverse-imaging it as per the Citrix documentation, and then installing the Target Device software and using XenConvert to create a new vDisk. Everything went perfectly until it actually came time to boot the target device from the vDisk. The dreaded BSOD! The 7B BSOD; which mean... read more.

Many Exchange 2010 administrators are familiar with working with database availability groups (DAG) and the multiple copies of mailbox stores they provide. One area of confusion around DAGs, however, is properly configuring DAG networks. This article reviews how to configure a multi-site DAG that consists of multiple networks. The example I will be using consists of Exchange Servers hosted in two physical locations. Each server has three network cards and resides on three different VLANs. For simplicity,... read more.
