I have a control which connects to an object on a server. This object has an
event, and client (the control) subscribes to this event. So something
happens on the server, it fires the event - the control is notified.
All this works just fine when the controll is hosted in a windows
application, but I have to host it in IE.
To make it work I asserted any permission I can think of (as a matter of
fact I asserted unrestricted for now) but it got me only so far. The control
creates the remoted object and it can subscribe to an event, but when the
server attempts to fire the event, it blows (see the text of the message
below in this post)

It looks like I still need to assert necessary permissions somewhere else,
but what permissions and where do I assert them - I have no clue. Any idea?

The text of the exception:

An unhandled exception of type 'System.Runtime.Remoting.RemotingException'
occurred in mscorlib.dll

the server: System.Security.SecurityException: Request for the permission of
