I have an application written in VB.NET that sends XML to another server and it takes another XML. I am using HttpWebRequest in sending it but when I get the request stream I got this error. Please note that the application is working on my machine, but on the deployment on server I got this error.

I'm having a doozy of a problem, and can't find a solution. I have a WFC Web Service installed to a pair of servers, and accessed through a load balancer. I am accessing the service from an ASP.NET client app, also via WCF. The Client is not load balanced.I'm getting an intermittant error:
(Inner Most Exception) System.Net.Sockets.SocketException: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond x.x.x.x:80(Middle Exception) System.Net.WebException: Unable to connect to the remote server(Outer Exception) System.ServiceModel.EndpointNotFoundException: Could not connect to http://<MYSite>/<MYApp>/<MYService>.svc.TCP error code 10060: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond x.x.x.x:80.
I can reproduce this error with about 20% reliability if I execute the exact same page request on the client from 2 browsers at the same time. When the problem occurs, the successful page request returns in about 5 seconds, and the failed page request returns in about 30 seconds.I'm guessing that there is some additional latency when the load balancer decides to switch my session to another server, and that is making some timeout setting on my client to be exceeded. I need to research this performance characteristic... any thoughtsbut its not my core question.My core question is... Exactly what setting can I tweak to increase the "period of time" the "connected party" is allows to "properly respond".This is the basicHttpBinding configuration I am using on both sides of the communication:
<basicHttpBinding>
<binding name="LongerTimeout"
sendTimeout="03:00:00"
maxReceivedMessageSize="2147483647"
maxBufferPoolSize="2147483647">
<readerQuotas maxArrayLength="2147483647" maxStringContentLength="2147483647"/>
</binding>
</basicHttpBinding>
I've seen some indication that setting the receiveTimeout value on the server may help, but I set this to 1 second in a test environment, and was unable to reproduce the problem, leads me to believe its not worth a production environment change to verify this.

I am using the codes sample from Peter through this link:http://www.eggheadcafe.com/articles/20030316.asp
to validate email address. I made some minor modification to validate user email address after the user have entered his or her email address as show below
string[] host = (address.Split('@'));
string hostname = host[1];
IPHostEntry IPhst =
Dns.Resolve(hostname);
IPEndPoint endPt =
new
IPEndPoint(IPhst.AddressList[0], 25);
Socket s =
new
Socket(endPt.AddressFamily,SocketType.Stream,
ProtocolType.Tcp);
s.Connect(endPt);
The last line of code s.Connect(endPt) generated the following error if the user email address is anything other than the company email address. I have try gmail, hotmail and they all generated the same error. Can the experts tell me how to get around the problem.
Here is the error:System.Net.Sockets.SocketException: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond 64.4.20.174:25

I'm using SQL 2005 for my current project. My remote hosting server uses port number 4433 for my database. So my connection string is as follows data source=IPaddress,4433;initial catalog=mydb;UID=sand;PWD=sand45;
But when connecting from my local machine from .NET or from SQL Management Studion it creates an error
A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections.(provider: TCP Provider, error: 0 - A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.

I have the problem of Timeout expired. The timeout period elapsed prior to obtaining a connection from the pool. This may have occurred because all pooled connections were in use and max pool size was reached.
I am opening and closing SqlConnection properly.

I was wondering if anyone knows of a good login stored procedure that can be freely used and features login limits and so on (basically a good one) With my limited SP knowledge, I've tried to create one myself, I haven't completed it yet as I'm not sure on how to compare the last login attempt time against the current time (it's in the comments).
P.S. I had to write this in notepad.

I need to create an application with Forms Authentication and/or Windows Authentication. If the application is set to use mixed authentication (Forms + Windows Auth) and the user don't have a Windows user account, the login will fail and he must be redirected to a forms login page. How can I do this?
Are there any different way to provide mixed authentication?

In Visual Studio 2005 I am following the steps to add a Web Reference to a web service.hings appear to go smoothly except for an error messae I am getting. Here are thesteps I follow along with the result.1. Right click on Web References folder and select "Add Web Reference..."2. When the dialog box appears I add the web service URL into the URL dialog box.The web service methods are then displayed in the dialog box with the links to each web service and a prompt to "Start Browsing for Web Service"However in the box to the right which is labeled "Web services found at this URL", there is an error messagewhich reads:There was an error downloading 'https://stage-serv/weatherQuote/WebService/weatherQuote.asmx
The underlying connection was closed: An unexpected error occurred on asend.Authentication failed because the remote party has closed the transport stream.I don't know what is causing this problem. I can reference this same web service on a productionserver just fine, but if I attempt to access it on the stagig server I get the message Ijust talked about.I am thinking that something is not configured on the staging server correctly.

I want to be able to run an ASP.NET application when a file is upload via FTP. I understand how to use the filewatcher class to monitor the directory but I don't know where to put the code so it is always running.
Files will be uploaded once per month for each group of users of the system and the next time the user logs on after the upload I would like the application to reflect the new data. I don't want to check for a new upload when each user logs on because the processing could take a log time.
The uploads are automatic from multiple other computer systems and not done by any user.
The Application is hosted (by GoDaddy) so I don't have full control of the server.
Is there any way to have a process running all the time in the background and if so how? The application is written in VB.net.

I'm getting the following error after uploading my site on live server:Timeout expired. The timeout period elapsed prior to obtaining a connection from the pool. This may have occurred because all pooled connections were in use and max pool size was reached.i'm using the following code:
public static IQueryable<Property> Properties(string name, string city, string state, int pageIndex, int pageSize, ref int total)

ServerDataContext server = new ServerDataContext();

return server.Properties.Where(x => x.Name.StartsWith(name) && x.City.StartsWith(city) && x.State.Contains(state)).Skip(pageIndex * pageSize - pageSize).Take(pageSize);

I want to redirect users when they reach a page in my web project. I want this to happen in page load after say 2 seconds.
I'm using this code on page load:
[Code]....
With this code, as soon as the page loads it redirects to that page. There are some text in this page that i want the user to see while the page is redirecting. What are my options? Should i use Timer? and tell it to redirect after two or three ticks?

Let's say we are building some public service that grabs the setup of a user (what server, user and pwd he wants to perform the call), logs in into that server and do some processing...
the process takes about 15 seconds to complete each user has a different setup (server/user/pwd), so the process needs to run against each one
if 1000 users tells the system to run the method at 1:00PM
How can I insure that the method is processed in the next 15 minutes?
What should be the correct approach to this little problem?
I'm thinking that I need to do something Asynchronously, and parallel processing could speed up things, maybe throttling the processes, maybe execute 100 calls per each 30 seconds?
I never did something like this and would love to get your feedback on ideas and future problems just to spend 100 hours of work and realize that I took a wrong road

My web site seems to be running quick. I have not deployed my web site yet, so I am the only one using it right now. The problem I have is if I am testing out the site and then I stop using it for a short period of time, when I come back the web site takes about 8-10 seconds to startup again. I did not rebuild the site I just simply stopped using it for a short period of time. It seems like after a short period of time I have to 'wake it up' again. Is this normal? How can I prevent this?
