I have all application errors sent to my email. I keep getting this:

i googled and read to add machineKey in my web.config <system.web> which i did: <machineKey validationKey='0EFA95136AEA44850D5CEDDF0CC7502B1A009.....' decryptionKey='E88EB13ADB2C3D395193AA71DBB1E...' validation='SHA1'/>
and added <pages masterPageFile enableViewStateMac="true" viewStateEncryptionMode="Auto"> to my masterpage.But i keep getting that error.
I am using following code to encrypt and decrypt files. It works fine in windows application but shows an error in asp.net class. It's using Riijandael method.
Error : padding is invalid and cannot be removed

We (out IT partner really) recently changed some DNS for a web farmed site we have so that the two production server have round-robin DNS switching between the two. Prior to this switch we didn't really have problems with WebResource.axd files. Since the switch, when we hit the live public URL, we get an error:
CryptographicException
Padding is invalid and cannot be removed.
When we hit the specific servers themselves, they load fine. I've researched the issue and it seems since they're sharing assets between two servers, we need to have a consistent machineKey in the web.config for each server so they can encrypt and decrypt consistently between the two. My questions are:
Can I generate a machineKey via a tool on the server, or do I need to write code to do this?
Do I just need to add the machineKey to the web.config on each server or do you think I'll need to do anything else to make the two server work together? (Both web.config's currently do not have a machineKey)
I'm using the ChangePassword method of membership provider to change the password and one of the requirement before calling the ChangePassword is to retrieve the current password. But I'm getting error:
I'm getting the following error in our QA environment but only through the IIS7 reverse proxy. If I hit the application server directly it works fine. In our DEV environment it works fine through the proxy or directly.
I'm not really sure where to go with this, Server Error in '/' Application.

We're getting this InternalSubStringWithChecks exception with our application's healthMonitoring. This exception is like the Padding is invalid and cannot be removed exception where it's being recorded and we're getting a notification email but the end user is unaware that an actual error has happened. Though we don't want our event log filled up with this rubbish! The stack trace is:

Since installing the security patch for the ASP.NET Oracle Padding vunerability any user that was keeping themselves logged in to our site is getting error messages when hitting any page.
With custom errors switched off a user sees the following information

We have a cookie management library that writes a cookie containing some sensitive information, encrypted with Rijndael. The cookie encrypts and decrypts fine in unit tests (using Moq), works fine for MVC web applications, but when called from an ASP.net 2.0 website, the cookie cannot be decrypted. "Padding is invalid and cannot be removed."
We are sure that the cookie value is valid because we tested it 10,000 times with random data in a unit test. There is something about what ASP.NET 2.0 does when it reads and writes the cookie that causes trouble.
App is imported in the parent web.config file, Tom and App have classes with the same names.To avoid errors resulting from ambiguous class names I removed the App namespace from the sub-directory where the Tom namespace is used.
However the namespace App is still imported on content pages that have a master page outside the Tom directory. This causes the aforementioned errors.Here is my dir structure
-Root Directory --Default.master --web.config (App is added in web.config) --Tom Sub-diretory ---web.config (App is removed in web.config) ---Content page that uses Default.master (Here is the problem) ---Page without master (Works OK)
I came up with the following error when i tried to run my asp.net application.
The error is : Unable to Attach.The Binding Handle is invalid.Do you wish to continue?
If i click Yes, application is running but could not able to debug.
Then I referred to microsoft blogs and tried the following solution control Panel-->Administrative tools-->Services-->Terminal ServicesI changed startup type to "Manual" ,restarted my machine.But it's not working for me.

When i try to encrypt it goes fine.. but when i right after try to decrypt it i get an:"Length of the data to decrypt is invalid" error... the error occours when i try to run the code FlushFinalBlock();here is my code:
I have IIS on S2k8 and a website with Windows Authentication only.
I can easily reproduce the following scenario, where HttpContext.Current.Request.LogonUserIdentity.Name has a bad value:
Login to website using FireFox, using an Active Directory account "user" (I could use IE to reproduce the same, but it's a few extra steps)Display <%=System.Web.HttpContext.Current.Request.LogonUserIdentity.Name%> on the pageIt shows "DOMAINuser", which is correctI go into Active Directory and rename the account to be "userX" instead of "user" (both SAMAccountName & UPN)Restart FireFoxLogin to website using "userX" accountThe page still shows "DOMAINuser", instead of the expected "DOMAINuserX"
It seems almost as if IIS has cached the old username and it's not showing me the new one, even though I explicitly enter it in the login prompt.
