Can you figure out what is the problem ?

I have .NET 3.5 installed. I have given all the permission but still not working.

Is it ADODB version peroblem or MSSQL server problem ?

Does user write permissions to the Temporary ASP.NET Files folder pose any security problems?

Joergen Bech — Wed, 08 Jul 2009 09:32:05 GMT

I am experiencing assembly binding failures due to insufficient permissions to the Temporary ASP.NET Files folder.

The application uses (web.config) Forms authentication with Impersonate = True and IIS Windows Integrated Authentication.

According to ASP.NET Identity Matrix, this means that the WindowsIdentity resolves to Domain\UserName and according to ASP.NET Required Access Control Lists (ACLs), the WindowsIdentity requires read/write permissions to the Temporary ASP.NET Files folder.

Using the Fusion log viewer, I can confirm that the assembly binding failure is due to Domain\UserName (belonging to the "Users" group in security) only having read permissions to this folder, but not write permissions.

The questions are:

Are there any security implications of assigning write permissions to the Temporary ASP.Net Files folder?

Is such a server configuration change commonly used? If not, why would WindowsIdentity resolve to Domain\UserName for this combination of web.config settings - or should this combination not be used in this context?

Note: The problem only occurs if a non-admin user is the first to hit the page. If the assembly has already been compiled and stored in Temporary ASP.NET Files due to an admin user hitting the page, there are no problems for subsequent users. I do NOT wish to place the assemblies in the GAC.

Hey Suzanne,

Could you please help me out for I am getting

System.IO.FileLoadException: Could not load file or assembly 'Interop.SHDocVw, Version=1.1.0.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040).

I am using this dll in my test project

The problem is that if I reference this dll in a separate project it works fine and gets loaded

However if I reference in my existing test project then It throws the mentioned error

I made sure to remove all the previous versions of Interop.shdocvw dlls and replaced it with that of System32 folder.

Helping to resolve this will be highly appreciated
