Encrypted Web.config on IIS 6.0, Win2k3

1.
created identity.aspx containing only the following:

<%@ Page Language="C#" %>
<%
Response.Write(System.Security.Principal.WindowsIdentity.GetCurrent().Name);
%>

In a browser, saw that the identity was
NT AUTHORITY\NETWORK SERVICE


2.
cd C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727


3.
C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727>aspnet_regiis -pa "NetFrameworkConfigurationKey" "NT AUTHORITY\NETWORK SERVICE"
Adding ACL for access to the RSA Key container...
The RSA key container was not found.
Failed!


4.
C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727>aspnet_regiis -pc "NetFrameworkConfigurationKey" -exp
Creating RSA Key container...
Succeeded!


5.
Tried step 3. again...

C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727>aspnet_regiis -pa "NetFrameworkConfigurationKey" "NT AUTHORITY\NETWORK SERVICE"
Adding ACL for access to the RSA Key container...
Succeeded!


6.
I have two websites, on different ports, both on the root URL /, so to distinguish them when encrypting the connection strings, I uses the site ID ( Identifier field in IIS Manager Web Sites list),

C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727>aspnet_regiis -pe "connectionStrings" -app "/" -site 1
Encrypting configuration section...
Succeeded!

C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727>aspnet_regiis -pe "connectionStrings" -app "/" -site 219934440
Encrypting configuration section...
Succeeded!


7.
I verified in a text editor the Web.config sections had been changed, and also that the running application was still able to read the connection strings.


8.
I did the same for the machineKey:

C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727>aspnet_regiis -pd "system.web/machineKey" -app "/" -site 219934440
Decrypting configuration section...
Succeeded!



9.
I tested decrypting the sections back to the originals:

C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727>aspnet_regiis -pd "connectionStrings" -app "/" -site 1
Decrypting configuration section...
Succeeded!

C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727>aspnet_regiis -pd "connectionStrings" -app "/" -site 2054359653
Decrypting configuration section...
Succeeded!
