I m having a database problem that I couldnt identify. The IIS loses connection to database once in 3 weeks. Once you restart the IIS everything is normal. Looks like IIS is fine because i can go to static pages. When I go to a page that requires database connection I get this error:
A transport-level error has occurred when sending the request to the server. (provider: TCP Provider, error: 0 - Either the application has not called WSAStartup, or WSAStartup failed.
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: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)
Is this a connection string problem?. because without changing anything if I restart the webserver all is fine. Is this a problem with application state?
Error at the transport level when sending a request to the server. (Provider: Shared Memory Provider, error: 0 - Since both ends of the canal there are no processes.)
I've got this exception on my Web Site every time after restarting my SqlServer on simple request like this :
if (System.Web.HttpContext.Current.User.IsInRole("Administrator"))
but after I do refresh the page with this codebehind error disappears.
How to handle this error and where it comes from ?

when a user enters a bad email I am doing a check on this and throwing an exception message as follows, this works fine on the test site but for some reason the same code on the live site gives a "internal server error" (http code 500). The code below:
[Code]....
not certain why this is happening, I assume that it's some server or config difference between the test and live sites. has anyone seen this before? For a quick fix i'm registering javascript alert and showing the same text so it works but I would like to figure out why the code above is not working.

I want some tips regarding sending mail ,I want to send bulk mail from my web application in c#. so ,what should be the best code for this and also what should be the best configuration used in the smtp server. because my current system fails to send 100 mails out of 400 mails in smtp server. I aslo used theading for sending this mail in batch of 30 mails in every 20 minute but it is not working . I want solution of both in my c# code and smtp and also is there any new solution in new technology like web services or any other option .
The question: Is it possible to configure multiple SMTP servers or update the SMTP object server information at runtime?
Description of problem: The site I'm working on has a few pages which send emails. Our site is using Gmail so even though it's a custom domain our email is sent out though Gmail SMTP servers.
Some emails come from the system and some emails come from users in certain groups. I have an SMTP server configured with the admin email for the system e.g. admin@mysite.com This works fine and when I get the email it shows from admin@mysite.comOne of our user groups let's call it "groupA" has an email configured on our domain i.e. groupA@mysite.com When I send the email and specify a from address for the MailMessage object as groupA@mysite.com it still shows up in my outlook as coming from admin@mysite.com I did a little further testing and if I specify both the from address and the ReplyTo as groupA@mysite.com it will show as From=admin@mysite.com but when I choose reply in outlook it shows groupA@mysite.com My best guess is that Gmail is overwriting the From address with the SMTP user to prevent email spoofing.
I found this: http://www.systemnetmail.com/faq/4.1.aspx but it won't work for me since group A, B, and C all need to send emails from the same page.
i'm using asp.net 3.5 and my site is hosted on godaddy i have a contact us form on the site. and i have to send the contact queries on [URL] which is hosted on godaddy. whenever i try sending mails i get this error

i tried changing smtp to relay-hosting.secureserver.net aswell. but it didn't work. i'm using this method of my classfile's sendmail class public void SendMessage(string From, string ToEmail, string subject,string body)
I have a serious problem with "Error on Page". The error message points to line number 939, char 13. In my code behind (C#) in line number 939 is only an obsolete method found which is no longer called. The aspx file has only 339 lines. What the heck is line number 939?The Webapplication allows a special user group to change some group memberships for members of another user group in Active Directory. The App handles 3internal DataViews derived from corresponding DataTables as DataSource for 3 GridViews and some other internal lists with objects (List<obj>).
It uses windows authentication to get current users credentials and his membership in the "Operators" group. This credentials will be passed-through to allow the process managing group memberships in active directory.After starting the App in browser it seems to work fine. But after an indeterminated time it doesn't longer respond. After each click on buttons (or link buttons) you only can see the message "Error on Page" in the browsers status bar below.I played with session timeout, storing the DataTables in session variables, without success.
Last week I found this article here: [URL]" and I addedEnableEventValidation="false" ViewStateEncryptionMode="Never" to Page declaration. However, at some point the the server does not respond. Each time the worker process on webserver recycles it seems the application turn to wrong state. Might be important: All controls including GridViews are embedded in an AJAX UpdatePanel. How to get a better error message? Debugging is enabled and Custom Error handling On, Off or Remote Only brings the same result as described.

I'm new to this forum. I was directed here from an Expression Web forum. I am using Expression Web, but this seemed like the most appropriate place to post. I have a site [URL] that uses masterpages and I'm having a problem...sometimes...when I publish the site.
I just got a new computer with Windows 7 and installed IIS, including support for ASP. I am running everything locally on my computer. A simple statement like <% response.write time() %> works fine, so ASP is working, However, when I try to run a page that accesses a database (at least, I am assuming that that is the root of the problem) then I get the unhelpful error message:An error occurred on the server when processing the URL. Please contact the system administrator.If you are the system administrator please click here to find out more about this error. I have no idea where to begin. the database is in the same location as it was on with my old computer, and I have adjusted permissions to the database so that everyone except Creator Owner has full permissions - for whatever reason I am not able to change Creator Owner permissions.
i am experiencing thi error when i click on the application in the remote machine.

What do i have to do to eliminate this error message?
I am receiving the following error on one of the web servers I support:
Event Type: Warning
Event Source: ASP.NET 2.0.50727.0
This is completely preventing access to the web site. Every attempt to access the website results in one of those error messages appearing in the event viewer. If I enable custom error pages on the website, I can see that same error.I have not been able to find any information whatsoever on what could be causing this.
