On Server 2012 R2 with XenApp 7.6 I noticed a strange phenomenon, when logging in, after the processing of my Group Policies my XenApp session would hang at a black screen for about 10 seconds
In large environments, oftentimes there can be lots of Citrix Policies involved. The XenApp 6.5 and XenDesktop 7.x Studio and AppCenter consoles currently do not have an easy mechanism to move policies around quickly. This, however, can be easily accomplished by the use of PowerShell.
Issue with CVAD 7.x where using Studio and PowerShell interchangeably can result in the error message "Changes made outside of this console, such as in PowerShell or management tools from previous versions, resulted in a discrepancy between policies. The assigned objects for policy "PolicyName" must match..."
For certain things like pushing policies to certain types of devices or applying monitoring policies, or even troubleshooting, it can be useful to know the end-point Operating System that a user is on from CVAD.
NetScaler Gateway SmartAccess depends on XML requests which need to be enabled. In the past, there was a policy to Trust Requests Sent to the XML Service Port, however, this policy has been removed from the Studio Policies
