Type.GetType Access is denied

[RichB]

Hello,

The .NET application I have just installed at a client web site is throwing
a strange error. At first the applications works without any problems, but
after 10 mins or so Access denied error messages are thrown.

The application, web based, late binds to a series of assemblies, none of
which are in the GAC. I have configured the application to impersonate the
IIS user and have set the user to have access to all relevant directories
(wwwroot, wwwroot/bin, Microsoft.Net/framework/v1.1.4322) and disabled the
index services service.

After digging a little deeper it seems the error is thrown when calling
Type.GetType, but like I mentioned earlier everything works fine but then
suddenly dies.

Can anybody think why this is the case and what I can do to resolve this
irritating problem.
Thanks

Richard.

Can you give you full text/call stack of the error message?

As I'm sure you've seen, the problem arises when it's trying to load the
xxx.Web.Custom assembly. The fact it's a FileLoadException (as opposed to a
TypeLoadException) to me says its a file system permission issue (as you
clearly suspected). You said you granted the IIS user access to wwwroot,
wwwroot/bin and the .NET Framework folder. I'm not sure if by "access" you
mean read/write or read-only, but you should verify the user has full
permissions for the "Microsoft.NET/Framework/v1.1.4322/Temporary ASP.NET
Files" folder and that these permissions are inherited by the subfolders.

If that doesn't fix it, do a test (if you haven't already) and have the
ASP.NET process run as a more privileged user (e.g. SYSTEM). See if that
fixes it -- at least that will verify it's a user-related permissions issue
(as opposed to some other .NET config issue).

Ken,

Thanks for the information.

Unfortunately, the IIS user has full control to Microsoft.NET directory and
all its children and it still fails. I have also changed the user to an
Admin user and it works, but causes problems because the user has to be
trusted on a SQL database.

At first I thought it could just be an issue with the client installation,
but after playing with a similar install back at the office I seem to get
the same problems when I change the port. At first everything is running as
expected, but then I get the "Access is denied" message.

Thankfully, I have found that by adding everyone to the Microsoft.NET
directory the problem is solved. Fortunately, this client is not so
concerned about security on directories, but I know for sure that certain
other clients will not allow everyone access.

Thanks

Richard.

P.S Once again thanks for the help, it is really appreciated.
