In my application I needs to stop a application pool programmitically in IIS 7. I have created a local acccount and given him Administrative Priviledges. Here is the code

Private static void StopApplication()
{
    string serviceHostDeploymentType = "local";
                if (serviceHostDeploymentType.Equals("local"))
                {
                    WindowsIdentityImpersonate newIdentity = new WindowsIdentityImpersonate();
                    if (newIdentity.Impersonate("AccountName", Environment.MachineName, "Password"))
                    {
                        try
                        {
                            ServerManager serverManager = ServerManager.OpenRemote("Server");
                            string siteName = GetWebSiteNameById(serverManager, 1);
                            Site parentWebsite = serverManager.Sites[siteName];

                            if (parentWebsite != null)
                            {
                                ApplicationPool apppool = serverManager.ApplicationPools["Application Pool Name"];

                                if (apppool != null)
                                {
                                    apppool.Stop();
                                }
                            }
                        }
                        finally
                        {
                            newIdentity.Undo();
                        }
                    }
                }
                else
                {
                   throw new ConfigurationErrorsException("...");
                }
    }

I am getting an error Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED)).
