View Planner client login to Desktop fails with ERROR "all available desktop sources for this desktop are currently busy"

Hi,

I am trying to start remote test using view planner. My clients are Win XP and the Desktop is Win 7.

When the test runs and use view client to login to Desktop it fails with "all available desktop sources for this desktop are currently busy"

I am using view planner 3.0.

I try using the View client to manully login to the vcenter server (using PCoIP) and that works fine.

I have to use RDP to run the remote test as PCoIP fails with this error on the desktop

Firewall is disabled Vcenter server, view and AD.

Will appreciate your help in resolving this

Thanks

Gagan
