I have developed a OWIN self host webApi application with angularjs 1.6 and c# .net. Am able to access my application on my LOCAL LAN network but unfortunately i lack in knowledge of setting it up a 'self hosted webApi' application over internet and am struggling it to work on internet. Am looking for some assistance.
`
static void Main()
{
bool first = false;
m = new Mutex(true, Application.ProductName.ToString(), out first);
if ((first))
{
// Specify the URI to use for the local host:
string baseUri = "http://*:8757";
Console.WriteLine("Starting web Server...");
WebApp.Start<Startup>(baseUri);
//MessageBox.Show("Server running at {0} - press Enter to quit. ", baseUri);
Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault(false);
Application.Run(new MainWindow());
}
else
{
MessageBox.Show(" Cannot start another instance of server !!!!!!!" + " ." + " " + "Server is running........");
}
}

I have Http server running on my PC, I can use localhost or 192.168.1.69 talk to the server.
I have a tablet in the same wifi as the PC, when I do 192.168.1.69:8080/hello
I don't get any response.
I tried set up port forwarding on router, added .exe to firewall trust, also tried use public ip(that open router login page) with port number. but they doesn't help,
public HttpServer(int port)
{
if (!HttpListener.IsSupported)
{
// Requires at least a Windows XP with Service Pack 2
throw new NotSupportedException(
"The Http Server cannot run on this operating system.");
} // end if HttpListener is not supported
_httpListener = new HttpListener();
_httpListener.Prefixes.Add("http://localhost:" + port + "/");
_httpListener.Prefixes.Add("http://192.168.1.69:" + port + "/");
_resourceLocator = new Locator();
}
public void Start()
{
if (!_httpListener.IsListening)
{
_httpListener.Start();
_running = true;
_connectionThread = new Thread(new ThreadStart(this.ConnectionThreadStart));
_connectionThread.Start();
}
}
I am trying to change IIS App Pool Identity (user) remotely using C# and getting an error
System.Runtime.InteropServices.COMException (0x800706BA): The RPC server is unavailable.
I am able to do it properly if I allow all RPC dynamic port (in the range of 49152 to 65535) from firewall for all services on a remote machine.
I just want to know the exact service or process name used by the remote system to complete the process so that I can allow the ports for that service only.
public static bool ChangeAppPoolUser(string ip, string machineName, string username, string password, string applicationPoolName)
{
try
{
var metabasePath = "IIS://" + ip + "/W3SVC/AppPools";
// Get list of appPools at specified metabasePath location
using (DirectoryEntry appPools = new DirectoryEntry(metabasePath, username, password))
{
if(appPools==null)
{
Helper.PrepareDebugLog("appPools is null");
}
Helper.PrepareDebugLog("metabasePath:" + metabasePath + " username:" + username + " password:" + password);
// From the list of appPools, Search and get the appPool
using (DirectoryEntry AppPool = appPools.Children.Find(applicationPoolName, "IIsApplicationPool"))
{
Helper.PrepareDebugLog("in");
if (AppPool != null)
{
AppPool.InvokeSet("AppPoolIdentityType", new Object[] { 3 });
// Configure username for the AppPool with above specified username
AppPool.InvokeSet("WAMUserName", new Object[] { Environment.UserDomainName + "\\" + Environment.UserName });
// Configure password for the AppPool with above specified password
AppPool.InvokeSet("WAMUserPass", new Object[] { CommonProgramVariables.localPassword });
// Write above settings to IIS metabase
AppPool.Invoke("SetInfo", null);
// Commit the above configuration changes that are written to metabase
AppPool.CommitChanges();
return true;
}
}
}
}
catch (Exception e)
{
Helper.PrepareLogWithTimstamp("EXCEPTION WHILE CHNAGE USER: Parameter USED machineName:" + machineName + " username:" + username + " password:" + password + " applicationPoolName:" + applicationPoolName + " LocalPassword:" + CommonProgramVariables.localPassword + " Local User:" + Environment.UserDomainName + "\\" + Environment.UserName);
Helper.PrepareLog("EXCEPTION:", e);
}
return false;
}
Expected: AppPool User should be changed for remote machine AppPool.
Actual result:
System.Runtime.InteropServices.COMException (0x800706BA): The RPC server is unavailable.
The error The RPC server is unavailable. (Exception from HRESULT: 0x800706BA) can occur if RPC / WMI connections are blocked on the target machine due to Firewall restrictions or you entered incorrect hostname / IP address of the target machine.
To resolve this error you could follow the below steps:
1)Open Control Panel, click Security and then click Windows Firewall.
2)Click Change Settings and then click the Exceptions tab.
3)In the Exceptions window, select the check box for Windows Management Instrumentation (WMI) to enable WMI traffic through the firewall.
There is something terribly wrong below but i just cannot figure out what.
Although the website is created like a charm, the Application pool that should be associated with it, is not created at all.
public string Create(string sitename)
{
try
{
using (ServerManager serverMgr = new ServerManager())
{
string strhostname = sitename + "." + domain;
string bindinginfo = ":80:" + strhostname;
if (!IsWebsiteExists(serverMgr.Sites, strhostname))
{
Site mySite = serverMgr.Sites.Add(strhostname, "http", bindinginfo, "C:\\admin\\" + domain);
ApplicationPool newPool = serverMgr.ApplicationPools.Add(strhostname);
newPool.ManagedRuntimeVersion = "v4.0";
newPool.ManagedPipelineMode = ManagedPipelineMode.Integrated;
serverMgr.CommitChanges();
return "Website " + strhostname + " added sucessfully";
}
else
{
return "Name should be unique, " + strhostname + " already exists.";
}
}
}
catch (Exception ex)
{
return ex.Message;
}
}
What am i doing wrong here?
What's happening here is that when you create your site it automatically gets assigned to the DefaultAppPool.
What you need to do is replace your site's root Application (/) and point it at the application pool you just created.
The easiest way to do this is to first clear your new site's Application collection, then add a new root application that points to your application pool.
Taking your code snippet I changed it to the following:
Site mySite = serverMgr.Sites.Add(strhostname, "http", bindinginfo, "C:\\admin\\" + domain);
// Clear Applications collection
mySite.Applications.Clear();
ApplicationPool newPool = serverMgr.ApplicationPools.Add(strhostname);
newPool.ManagedRuntimeVersion = "v4.0";
newPool.ManagedPipelineMode = ManagedPipelineMode.Integrated;
// Create new root app and specify new application pool
Application app = mySite.Applications.Add("/", "C:\\admin\\" + domain);
app.ApplicationPoolName = strhostname;
serverMgr.CommitChanges();
I wouldnt expect the App Pool name to have punctuation in it. Adding the domain as part of the app pool name is a little unusual - perhaps thats the source. The basic method is discussed here, along with the appcmd syntax to make the same thing happen on the command line - try creating your app pool on the cmd line to see if your parameters are acceptable.
Create an application pool that uses .NET 4.0
I have a console app written in C# that uses MS Fax (FAXCOMEXLib) to send faxes. If I run the application manually or from a command prompt it works as expected. If I schedule the application with Task Scheduler or try to run from a service with a timer, it fails when calling the ConnectedSubmit2 on the FaxDocument object. The application runs as expected, gets the data, creates the pdf, connects to Fax Service, fills the FaxDocument properties, but bombs on ConnectedSubmit2. It feels like a security issue. The windows account the TaskScheduler runs under belongs to the administrator group.
This same application has worked on another Server 2008 (not R2) computer without issue with Task Scheduler.
The server in question is running Microsoft Server 2008 R2.
Recap: The application will work if run manually, fails if run from another process like Task Scheduler.
Any suggestions would be most appreciated. Thank you.
C# Code:
FAXCOMEXLib.FaxServer faxServer = new FAXCOMEXLib.FaxServer();
FAXCOMEXLib.FaxDocument faxDocument = new FAXCOMEXLib.FaxDocument();
ArrayList al = new ArrayList();
al.Add(orderPdfFilePath);
if (facesheetPdfFilePath != "")
al.Add(facesheetPdfFilePath);
if (write) Console.WriteLine("Preparing to Connect to Fax Server...");
sbLog.Append("Preparing to Connect to Fax Server...\r\n");
faxServer.Connect("");
if (write) Console.WriteLine("Connected.");
sbLog.Append("Connected.\r\n");
// Add Sender Information to outgoing fax
faxDocument.Sender.Name = dr2["FacilityName"].ToString();
faxDocument.Sender.Department = dr2["TSID"].ToString();
faxDocument.Sender.TSID = Truncate(dr2["TSID"].ToString(), 20);
faxDocument.Recipients.Add(dr2["FaxNumber"].ToString(), dr2["Pharmacy"].ToString());
faxDocument.Bodies = al.ToArray(typeof(string));
faxDocument.Subject = order;
if (write) Console.WriteLine("Attempting submit to fax server...");
sbLog.Append("Attempting submit to fax server...\r\n");
// attempt send...
try
{
object o;
faxDocument.ConnectedSubmit2(faxServer, out o);

We just started up a new webserver and i'm running into "class not registered" when creating a new application pool. I'm using the code below but I have no idea how to distinguish what is not registered. Any thoughts would be awesome.
Thanks.
string path = "IIS://" + server + "/W3SVC";
string app_pools_path = path + "/AppPools";
/error below.
var app_pools = new DirectoryEntry(app_pools_path);
foreach (DirectoryEntry app_pool in app_pools.Children)
{
//do work
}
Error "Class no registered" error code:2147221164
ON the server open the server manager
add new features ==> Web Server (IIS) ==> Management Tools ==> IIS 6 Management Compatibility then check IIS6 Metabase Compatibility. use your original connection string / path
string path = "IIS://" + server + "/W3SVC";
string app_pools_path = path + "/AppPools";
try this please :
private void StopAppPool(string app_Pool , string server)
{
try
{
ConnectionOptions co = new ConnectionOptions();
co.Username = "DomainName\\UserName";
co.Password = "UserPassword";
string appPool = "W3SVC/AppPools/" + app_Pool;
co.Impersonation = ImpersonationLevel.Impersonate;
co.Authentication = AuthenticationLevel.PacketPrivacy;
string objPath = "IISApplicationPool.Name='" + appPool + "'";
ManagementScope scope = new ManagementScope(#"\\" + server + #"\root\MicrosoftIISv2", co);
using (ManagementObject mc = new ManagementObject(objPath))
{
mc.Scope = scope;
mc.InvokeMethod("Stop", null, null);
}
}
catch (Exception e)
{
Console.WriteLine(e.Message);
Console.WriteLine(e.StackTrace);
Console.WriteLine(e.InnerException);
Console.WriteLine(e.Data);
}
//Console.ReadLine();
}
You should avoid using DirectoryEntry to manipulate IIS 7 and above. That's the old API based on IIS ADSI interfaces,
http://msdn.microsoft.com/en-us/library/ms524896(v=vs.90).aspx
IIS 6 Compatibilities might help you out though,

The best solution (which is also strong typed and more convenient for C# developers) is Microsoft.Web.Administration,
