Question

To enable or disable a user on local computer, I am using the following snippet.

DirectoryEntry localMachine = new DirectoryEntry("WinNT://" + Environment.MachineName);
DirectoryEntry currentUser = localMachine.Children.Find(user, "Administrators");
currentUser.Invoke("AccountDisabled", new object[] { true });
currentUser.CommitChanges();

I am assigning user as a string. I am getting a “filepath not found error”: Comexception Unhandled.

Is anything wrong with my code ?

According to the MSDN Page for DirectoryEntry:

Connect to a user on a computer. For example, “WinNT://<domain name>/<computer name>/<user name>“. If you are connecting to a local computer, “WinNT://<computer name>/<user name>“.

So, your code to grab the user should be:

DirectoryEntry currentUser = new DirectoryEntry("WinNT://" + Environment.MachineName + "/" + user);
