Thanks to every one who help in this issue:
i have integrated a web report in an asp.net 2 page.
it is working properly in my pc which has iis 5 and win XP but in my server
it throws an error telling me the Reporting Assemblies cannot be load.
i looked at assemblies installed in my server and all assemblies related to
reporting are installed and it is same version as in my pc.
the server is win 2003
you can see the error here:
