Hi Niraj,
Thank you for the explanation.
As i can view the crystal reports without any problem so i think that the BO server 10.x is indirectly accessible from internet via the Integration Option for Sharepoint Software (IOMS).
Do you think that i have to include (to-ports="*" ) to crossdomain.xml or it doesn't make difference
<allow-access-from domain="*" to-ports="*" secure="false" />
Thank You
