Access Denied when launching Citrix Published Application

Hi Experts,

I have an issue with a user that has been granted access to a published application on our Citrix XenApp 6.5 farm, he can see it when he goes through the web interface and Program Neighbourhood but he gets an "access denied" as though he is trying to log onto one of the Citrix servers itself. He has the Receiver installed on his machine, and I've checked his in a group that can access the application, not sure what the cause could be.

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

I'm assuming the user was a member of the Remote Desktop Users Group on the target server?

Run dscheck /clean on Data Collector once done then run gpupdate /force and check.

Hi Brian, Yeah the Domain Users group is a member or the Remote Desktop Users Group. Sehar I did run dscheck on the Data Collector and it did find one reference to an unknown object but I have not poerformed a  dscheck/clean. The article seems to have done the trick, though I am kind of concerned as to what dscheck has brought up.
