What the SHA is going on with my Citrix Access?!? The news is that SHA1, a very popular hashing function, is on the way out. Strictly speaking, this development is not new. The first signs of weaknesses in SHA1 appeared (almost) ten years ago. In 2012, some calculations showed how breaking SHA1 is becoming feasible for those who can afford it. In November 2013, Microsoft announced that they wouldn't be accepting SHA1 certificates after 2016. So what does this mean to you and your Citrix Environment? To u... read more.

Many customers that are using Microsoft Threat Management Gateway (TMG) already know that Microsoft will not be releasing any new versions or updates (minus security updates). While TMG is still supported (extended) by Microsoft until 2020, there are other options out there that should be considered. Recently Gotham worked with a customer to replace the TMG environment that was front-ending their global SharePoint solution with a NetScaler MPX 5500 solution to provide the following: Authentication pag... read more.

Windows XP end-of-life (EOL) was highly publicized. Some companies have been in the clear for awhile, others made a mad dash to the finish, while a few are still struggling (http://www.crn.com/news/applications-os/300072525/irs-misses-windows-xp-deadline-inks-extended-support-deal-with-microsoft.htm). But, I can say it has been on people's radar for awhile. Windows 2003 seems to be the sleeper. Windows 2003 will reach EOL in July 2015. Server upgrades are a different type of challenge, as they support ap... read more.

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.
