This is my problem. I am using Visual 2003, .Net framework 1.1 and the
Application Block
I configured the DAAB using the Enterprise Library Configuration

now this is the error which is coming

Hi Ankit,

Thank you for posting.

From your description, I understand that you have an ASP.NET web
application which use the enterprise library and DAAB. However, at runtime,
you're encountering some System.Security Exception, correct?

Based on the error message and callstack, the exception occured when the
code try accessing certain windows registry entry. So this is a security
permission problem. I suggest you try the following steps first:

1. Change your ASP.NET application's process idenitity to LOCAL SYSTEM and
run it to see whether the problem still occurs. If still occurs, that means
this is not a raw windows security issue, but a .NET code access security
issue. If the problem go away, we need to check the original process
identity's windows permission to the registry.

2. If we've confirmed that this is a .NET CAS issue through #1, we need to
check our asp.net application's Trust Level first, is your ASP.NET
application running under "Full" trustlevel? The trust level can be
configured in the web.config(or machine.config) through the <trust> element:

#trust Element (ASP.NET Settings Schema)
http://msdn2.microsoft.com/en-us/lib...93(VS.80).aspx

If the original value is not set as "Full" , you can manually set the
application's Trust level to "Full", like below:

<trust
level="Full"
/>
After that, test the application again to see whether it can run
correctly(acces s the registry correctly).

Hope this helps.

Steven Cheng

hey Ankit,
this is the problem of registry settings in Enterprise Library.
Just run the batch file of "Install Services" provided in the Enterprise
Library. I hope it may solve ur problem.

Thanks for your response Ankit,

What's your webserver's OS version and is it using IIS5 or IIS6? As for
the step1 I mentioned before, it depend on the IIS server your application
running against. For IIS 5, it use the ASP.NET processModel, you can change
ASP.NET process idenitity through the <processModel > element in the
machine.config file. For IIS6, it by default use applicationPool model, so
you can just configure your ASP.NET application(vir utal dir)'s application
pool's idenitity account. Change the account to LocalSystem and test it to
see whether it works

for IIS5
#<processModel > Element
http://msdn.microsoft.com/library/en...cessmodelsecti
on.asp?frame=tr ue
for IIS6
#Identity Application Pool Settings
http://msdn.microsoft.com/library/en...tityapplicatio
npoolsettings.a sp?frame=true

if change process idenitity to run under LOCALSYSTEM not work, you should
check the .NET CAS setting as I mentioned in step2:

#ASP.NET Trust Levels and Policy Files
http://msdn.microsoft.com/library/en...ettrustlevelsp
olicyfiles.asp? frame=true
