Citrix vs VMware

March 2nd, 2015 Posted by Citrix, Hyper-V, vmware No Comment yet

Which one is better Citrix or VMware for desktop and application delivery? We sometimes hear this question from our clients. Unfortunately, more often we hear, “We have chosen [insert product/vendor here] because it is better.” The “better” decision usually comes from reading vendor whitepapers, personal or friend’s experience, blog posts and such.

So which one is better? I would answer this question with classic consultant’s “It depends…” There is a solution out there that will be better for you. Whether it be Citrix or VMware, this is what you need to find out and this process is not easy.

Let’s review both vendors’ points of why their product is more superior than the competitor’s. Not a surprise that you will find a number of whitepapers, blog posts and articles uncovering various pieces of technology and explaining what exactly their main differentiators are, but let’s take a look at major vendor whitepapers from VMware and Citrix. Each one has four main reasons to go with a particular vendor.

.NET 4.5.2 Update on Exchange Servers?

January 19th, 2015 Posted by Exchange 2013 No Comment yet

Microsoft Windows Update is now offering the .NET Framework 4.5.2 update as an “Important” update to Windows computers.

  • Microsoft .NET Framework 4.5.2 for Windows 8.1 and Windows Server 2012 R2 for x64-based Systems (KB2934520)
  • Microsoft .NET Framework 4.5.2 for Windows Server 2008 R2 for x64-based Systems (KB2901983)

First of all, keep in mind that both of these updates require a restart. It’s also important to mention that .NET Framework 4.5.2 is only supported and recommended for Exchange 2013 CU7, but it is being offered as an Important update to all Windows servers.

When this update is installed on your Windows servers it will re-optimize all .NET assemblies on the server when it restarts. Perfmon shows ~99% of CPU resources are in use for about 15-20 minutes while this occurs.

We recommend putting servers into maintenance mode on the load balancer prior to updating them and re-enabling them once optimization completes!

January 14th, 2015 Posted by Security No Comment yet

Dell SecureWorks Counter Threat Unit(TM) (CTU) researchers discovered malware that bypasses authentication on Active Directory (AD) systems that implement single-factor (password only) authentication. Threat actors can use a password of their choosing to authenticate as any user. This malware was given the name “Skeleton Key.” (more…)
