load dll permissions problem

[ghell]

my webserver (iis6.0) has a virtual dir called public, i put a dll in public\bin\ (on my computer using iis5.1 its just in c:\inetpub\wwwroot\bin\) and it stopped saying the cant find file error and now saysParser Error Message: Required permissions cannot be acquired.

i cant find anywhere to set these, i set them all up to everything on iis (i think) and dirs but it still says it, where can i change persmissions to get this working?

EDIT: ok, it turns out removing the dll (http://www.carlosag.net/Tools/WebChart/) from the bin directory gets asp.net working again but how can i put this dll on without it breaking, on xppro it was no problem, what do i have to do to avoid this problem on ws2k3?

make sure that the file is not marked as readonly and that your asp.net account has access to the folder and the file.
