I have XenServer 5.6.1 installed on an HP DL380 G7.
2 Virtualised Svr 2008r2 servers running XenApp6 farm.
The client machines have SmartCard Readers attached (required).
The CTXSmartcardSVC seems to cause the CTXSVCHost.exe to run very high CPU Usage.
Stop the CTXSmartcardSVC and CPU usage drops but then the smart cards don't work.
It is critical the smartcards work but the published desktop runs slowly.
Hope someone can help,
