Hi,

I have an assembly (.exe) started at logon of each computer of my company
and for each user. (Through PDC scripts)

This assembly use web services in order to request any informations.

When my exe is executed, i have this exception :

.... It sounds like your code (exe) doesn't have permission to access the
web... This can be caused by if your exe is not located on the local hard
drive, but running from a network share or such. (by running from the local
HD, your code gets all permissions... unless it has been changed from the
default by the Administrator of the domain or such... in which case, you'd
have to ask your administrator for what he/she could do about getting more
permissions for your assembly)

I've got some blog entries about Code Access Security (CAS), which could be
quite helpful in examining your assembly's permissions, and understanding
the implications of where it is running from (and to examine which "zone"
you would need to run it under in order to have the correct permissions).

My CAS blog is here:
http://cactidevelopers.resdev.net/Product%20Guides/ProductBlog.aspx?GuideID=66dcc35e-340a-18b0-69c8-45ed4f806c7e

Specifically, after reading a little bit about how CAS works... I think this
entry might be most helpful in helping to understand the proper direction
you would need to take or research to get what you need done:

http://cactidevelopers.resdev.net/Product%20Guides/ProductGuideEntry.aspx?GuideID=66dcc35e-340a-18b0-69c8-45ed4f806c7e&EntryID=78e62cf5-5953-2bb2-ab80-8088a186a154

Hope this helps!
