I have created an ASP.Net website and tested it using the default server. I used the integrated membership provider for the users login and everything worked fine.
Now I moved to IIS 7 and nothing works anymore. I disabled the read-only feature but every time I try to either register a new user or add an item to the chart I get this error
Cannot open user default database. Login failed.
Login failed for user 'NT AUTHORITYNETWORK SERVICE'.
Ok this one might be a bit tough to figure out, but each day when users open their application the following error is generated and they can not enter the application: "Failed to decrypt using provider 'EncryptionProvider'. Error message from the provider: The RSA key container could not be opened." Guess what fixes it... I have to open the application 1 time and then all of the users can being to open the application. This is not an issue with the encryption/decryption of the .config never having worked; it works just fine - but not all of the time. It sounds like a permissions issue to me, like me opening the app grants access to the key file for a time period, and the next day the issue starts all over again. Here is what I have already done (actually when I set up encryption originally), as the many, many posts with this issue are resolved with, but none have worked:
- aspnet_regiis -pa "MyWebKeys" "NT AuthorityNETWORK SERVICE"
- aspnet_regiis -pa "MyWebKeys" "ASPNET"
- Gave ASPNET account read access to "C:Documents and SettingsAll UsersApplication DataMicrosoftCryptoRSAMachineKeys" folder
- Gave NETWORK SERVICE account read access to "C:Documents and SettingsAll UsersApplication DataMicrosoftCryptoRSAMachineKeys" folder
I did not do the following, since I am not using the deafult machinekeys, but rather the imported "MyWebKeys" container
- aspnet_regiis -pa "NetFrameworkConfigurationKey" "NT AuthorityNETWORK SERVICE"
- aspnet_regiis -pa "NetFrameworkConfigurationKey" "ASPNET"
Here is how the file is encrypted:
aspnet_regiis -pef "appSettings" "C:MyProject" -prov "MyEncryptionProvider"
"MyWebKeys" are an imported key container on the server, that upon importing reside in the default "C:Documents and SettingsAll UsersApplication DataMicrosoftCryptoRSAMachineKeys" directory. So it appears I have covered everything, right? What am I missing? Do I have to add individual users or groups with the pa command that use my application to allow access to the container? Remember the encryption/decryption does work 95% of the time. It just seems that each day in the morning, I must open the app once prior to the users being able to open the application, which tells me it is a permissions issue because I am an Admin on the server and they are not, but I thought all of this runs under the NETWORK SERVICE account anyways?)

I am trying to copy a website from one server to another, however I am getting the error above
<connectionStrings configProtectionProvider="WSConfigProvider">
Line 51: <EncryptedData Type="http://www.w3.org/2001/04/xmlenc#Element"

Line 53: <EncryptionMethod Algorithm="http://www.w3.org/2001/04/xmlenc#tripledes-cbc" />
I have copied the entire site so cant think what file it could be missing, however looking at the article [URL] .... I cannot seem to find the location Documents and Settings{UserName}Application DataMicrosoftCryptoRSA on the server, where would this be on a 2008r2 server? And is there some files in there missing which could be causing this error?

I am writing a page for creating a new user for a website. After the user fills out the form and click the "Create User" button, the information provided is supposed to be sent for storage to the database. I have been getting the same error message for a couple of days now and I've ran out of things to try. The message doesn't seem like a complicated issue, in fact it's quite common and found a great deal of information on how to resolve it. However, nothing I've tried works. I'm using VS 2010, and SQL Server Express 2005. The message I get is the following:Cannot open database "[database]" requested by the login. The login failed.Login failed for user "[MACHINE_NAMEUSER]".I have added my current Windows account to the Users folder under the Security folder through Management Studio and granted it all the role memberships. I'm also using Windows authentication. If there's any information I'm not providing to figure out what's the issue, let me know and I'll post it.Stack Trace:

Currently using VS 2005 & MS SQL 2005 Server with a Windows 7 OS and I am unable to generate Update/Insert/Delete queries when using the TableAdapter wizard. I am able to create the Select statament.

I have seached the web but no one seems to have seen this same issue.
If you know what is causing this let me know. I didn't have this issue while running a XP or Vista OS.

Source Error:
The source code that generated this unhandled exception can only be shown when compiled in debug mode. To enable this, follow one of the below steps, then request the URL:
1. Add a "Debug=true" directive at the top of the file that generated the error. Example:
<%@ Page Language="C#" Debug="true" %>
or:
2) Add the following section to the configuration file of your application:
<configuration>
<system.web>
<compilation debug="true"/>
</system.web>
</configuration>
Note that this second technique will cause all files within a given application to be compiled in debug mode. The first technique will cause only that particular file to be compiled in debug mode.
Important: Running applications in debug mode does incur a memory/performance overhead. You should make sure that an application has debugging disabled before deploying into production scenario.
