dll error in a webform page???

During execution of a multi-tiered website, I get the following error that .Net can't load the following DLL (nOTICE THE DataAccessLayer.DLL)

Parser Error Message: Access is denied: 'DataAccessLayer'.

Source Error:


Line 196: <add assembly="System.EnterpriseServices, Version=1.0.5000.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a"/>

Source File: c:\winnt\microsoft.net\framework\v1.1.4322\Config\ machine.config Line: 198

Once I place the new version of this dll in the following directory "c:/inetpub/wwwroot/Nicem_Scheduling/bin", it works fine.

On subsequent executions of the same web page, I get the above error even though I havn't changed any settings or code on any of my 3 tiers.

I checked to make sure that the ASPNET user has Admin rights, which it does.

How can I resolve this situation?
