Once login to HSD and tried to login StoreFront. Then receiving "There are no apps or desktops available to you at this time."

do you get the apps if you specify username/password?
If SSO is broken, you should be unable to logon using SSO .. but not logon and get an empty store.

do you use a browser or installed receiver?
... try using the browser ... result?
do you use a NetScaler within your installation?

within a current client (receiver) you see the option "configuration-check". Try this ... result?

Thanks for your response.
I am using StoreFront only. So SSL.
yes, I have Receiver with Include SSON .

Yes, SSL is required for SSO configuration. Once I configured SSL then all GPOs are working fine. Now I am able to see published Applications on Citrix Receiver.
But when I tried to access any application, I am receiving Citrix Receiver error "Cannot start app. Please contact your help desk"
Please suggest.

It#s a new problem ...
would suggest to ask a new question.
So other experts can take a look too.

...
- check for connection-error-messages within Director.
- are the servers registred within studio
- is maintenance-mode enabled for server or group
- are the firewall rules at the xenapp servers configured?
- check with netstat -n while client tries to connect ... some connections in "SYS SEND" state?

Thankyou
