Jakiej biblioteki używasz(bo to jak sądzę System.Net.Sockets.Socket czy pokrewna nie jest)? Jak wygląda kod? Strzelanie na ślepo tutaj niewiele da.
Public Class Form1 Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click winsock.RemoteHost = "184.108.40.206" winsock.RemotePort = 234 winsock.Connect() End Sub Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Dim wysylanie As String If tekst.Text = "" Then Exit Sub End If wysylanie = tekst.Text winsock.SendData(wysylanie) End Sub End Class
Oznacza to ;
Używasz Winsock ; Twój serwer blokuje wysłanie.
Exception from HRESULT: 0x800A9C46
What does this mean??? Exception from HRESULT: 0x800A9C46
When the cpu usage rises, some of the winsocks loaded give this error... The number of winsocks loaded is very high (more than 1000)

Just why are you using Winsock? That is a bad idea, since .NET already has perfectly usable (and fairly well designed) libraries to accomplish the same task inside the System.Net namespace, and it is far better performant since it requires no COM interop.
There are several good tutorials/examples on using the .NET classes here and here, and several others that can be found by just searching google. Try them first.

How to use HttpWebRequest to send POST request to another web server?
In classic ASP applications we had the flexibility of having multiple form tags on the same page and each form could have different target URLs and different method types. This has been kind of a limiting factor in ASP.Net applications. But this does not mean that it can not be accomplished. Micorosoft .Net framework has a very rich library and provides answers to most of the questions. It has a very handy HttpWebRequest class that can be used to send HTTP requests to any server.
Where do I need to use it?
Its is important to know where this feature is required. A very good example is if you are using Paypal to accept payments for your e-commerce application. It requires that you set up your shopping cart button to submit a POST request with all the required information. Following is an example from Paypal's developer support web site.
border="0" name="submit" alt="Make payments with PayPal!">
You can see that when you click on this button, a form will be submitted to paypal. The problem is that ASP.Net does not allow embedding of second form tag inside the main form.
How will I do it?
We will gather all the required information from the user on a regular ASPX page. And then when user clicks button to submitt information for shopping cart, then we will use HttpWebRequest object to submit the request to target web server. The following illustrates how values from two text box controls are sent to a target web server. This example does not correspond to the fields described in the Paypal example.
private void OnPostInfoClick(object sender, System.EventArgs e)
string strId = UserId_TextBox.Text;
string strName = Name_TextBox.Text;
ASCIIEncoding encoding=new ASCIIEncoding();
postData += ("&username="+strName);
byte data = encoding.GetBytes(postData);
// Prepare web request...
HttpWebRequest myRequest =
myRequest.Method = "POST";
myRequest.ContentLength = data.Length;
// Send the data.
If your server is capable of sending compressed response, read our article How to use Accept-Encoding HTTP Header for more details about it.
