When the user accesses the published XenApp application with .NET or Java component, first time user logon to the published application takes long time to appear after first click over the application. The application appears after a time out that varies and after appearing, the applications behave as expected.

In other cases, the application is started correctly but during scenarios such as execution or accessing different module of the application, this access might take more time to process or fail in some cases.

This behavior occurs when the servers where the applications are published do not have Internet access and these applications have some.NET or Java component certificate that must be verified. If the server does not have Internet access, then the .NET framework or Java component cannot access the crl.microsoft.com website to verify that the digital signatures that are used to sign the binaries for managed applications are valid. Each certificate check has a 15 second timeout in the .NET runtime implementation. Depending on what features are installed, this can add up to a minute of startup time for the application.

Resolution

Internet Properties

Open User Configuration > Administrative Templates > Windows Components > Internet Explorer > Internet Control Panel > Advanced Page.

The options that must be set to disable value are:
