Problem Cause

The timeout occurs when the WEM agent collects user information for the CVAD Session Launch Event and it only occurs for the ICA session, which is not needed for the RDP session. So the problem only occurs in CVAD environment. It seems the Microsoft API FindByIdentity may cause such delayed time which can be avoided by disabling NetBIOS over TCP/IP on all Hypervisor-Switch network interfaces. AD routing related issues can contribute to this additionally
