Some users have reported the existence of the ASP.Net machine account. In this article, I will discuss what is asp.net machine account in windows 10/7 and how to disable it, asp.net machine account password, and can I delete the asp.net machine account?

In this article I will explain with an example, how to get Client IP Address of Visitor’s Machine in ASP.Net using C# and VB.Net. This article will explain how to get IP Address of Visitors (Client) Machines which don’t use Proxy Servers and also which are behind Proxy Servers in ASP.Net using C# and VB.Net.

What is the ASP.Net Machine Account?

.NET Framework is an application on Windows that requires the installation to run several apps or games. However, when the .NET Framework is downloaded and installed, the application automatically creates an ASP NET machine account. The application does not take user permission or ask for a password before creating an ASP NET machine account windows 7 or Windows 10.

Some users have reported having been asked for ASP.NET Machine Account Password for logging in, which means while they can use the computer with the user account, they can’t have access to the second account- ASP.NET machine account windows 10 or windows 7.

Asp.net Machine Account

It is mostly recommended to people to remove the account as soon as possible to ensure safety for your system, but if you are a software developer and sure of handling it your way, you may choose to keep it.

Can I delete asp.net machine account

The simple answer to the above question is Yes. Find the following methods to delete this unwanted account created by the .NET Framework.

Method 1: Reinstalling the .Net Framework. Find the below steps to reinstall the application .NET Framework and delete the machine account.

• Re-download the .NET Framework from the Microsoft website.

• Run the .exe file and you might get a pop-up notification with the message that it is already installed and have the option to cancel or reinstall the file.

• Choose the reinstall option to solve the issue of the second administrator account on your Windows OS and that too password protected.

• Re-installation will remove the misconfiguration in the file and eventually remove the ASP dot NET machine account on your system.

• After the re-installation is complete, reboot your system to check if the problem persists.

• Congratulations on succeeding if you did, if not, then no need to worry, you have the next method to try and delete the unwanted account.

Method 2: Delete the account and leave the .NET Framework installed:

• Open the Control Panel -> Goto Administrative Tools folder and select the Computer Management option.

• Select the Local Users and Groups node.

• Click on the Users sub-node and select the ASPNET account.

• Right-click on the selected account and select Delete.

Conclusion

I hope you liked this article on the asp.net machine account. I would like to have feedback from my blog readers. Your valuable feedback, question, or comments about this article are always welcome.

It’s quite common to need to preserve state across requests in a web application. This is typically in the form of a cookie, query string or hidden form field. Commonly the state that needs to be sent back to the client is sensitive or we want to ensure it’s not been modified by the user. The typical approach to this should be encrypting (protect) and MACing (verify) the value. Writing this sort of crypto code yourself is possible but not ideal. Fortunately in ASP.NET the MachineKey API already provides this functionality. And yes, this is the same as the <machineKey> infrastructure already used to protect Forms authentication and ViewState.

The API is slightly different between 4.0 and 4.5. Here’s the 4.0 usage with some helpers:

MachineKey.Encode accepts a byte[] to protect and returns a string. The second parameter is an enum that indicates if you want encryption, validation or both. I’d typically suggest both (MachineKeyProtection.All). The returned string can then be used to pass back to the client as a cookie value or a query string value without concern for viewing or tampering. MachineKey.Decode simply reverses the process.

And here’s the 4.5 usage (it supports a slightly more sophisticated usage):

In 4.5 the old APIs are deprecated in favor of these new Protect and Unprotect APIs. The new APIs no longer accept the level of protection (they always encrypt and MAC now [which is good]) and instead now accept a new parameter which is called “purpose”. This purpose parameter is intended to act somewhat as a validation mechanism. If we use a value that’s specific to the user (as we do above with the GetMachineKeyPurpose helper) we then are verifying that the value can only be unprotected by the same user. This is a nice addition in 4.5.

In my Cookie-based TempData provider I used this exact technique — I didn’t want to reinvent crypto or introduce new keys, so leveraging the ASP.NET machine key APIs made a lot of sense.

Oh and one caveat: this does not prevent an eavesdropper from intercepting the value and replaying it, so (as usual) SSL is imperative.
