I am using Sql Server 2008 to connect to a Remote Server. Everything was working fine for the last couple of months, and i was successfully connecting to the remote server. Today it suddenly stopped connecting to the remote server. note that i did not alter any configuration settings. Did my isp block Sql Server. My ISP is using ISA SERVER? The error details are:
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) (.Net SqlClient Data Provider) I am using Microsoft Firewall Client For ISA Server for opening ports. But today nothing is working.
I recently did an OS reinstall and tried to use my previously-working projects. I found that there was trouble connecting to the database for my aspnetdb.mdf. I have also tried a new project and adding a database to the project but I get the error 'a network related or instance specific...' error. I have tried reinstalling sql server 2005 express but still no luck. When I fire up sql server management studio i see the server name is the same as my computer name. I remember before the os reinstall that the server name was 'sqlexpress'.Anybody got any ideas as to how I can create databases inside of visual web developer again?

I've created a small website with a simple sqlite database using vwd 2010 .net 4. In dev and test envionments everything works fine, however when i promote to my hosting provider i receive the following error:

(provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)
I've been configuring the connection strings (autogenerated from entity framework and attached db) but unable to get it working on the hosting provider, I'm assuming it's related to permissions but not entirely sure how to resolve - here's the web.config as it stands:
<add

For info the environments are set up as follows:
- Dev environment is vwd express 2010 with sqlite mdf attached
- Test environment is windows 7 server, iis 7 with appdomain identity set to network service

I am REALLY stuck with this and need a solution in the next 24 hours .i I have uploaded my asp.net web application to the web and have the database and connection strings functioning and reading the data from the database. But when I try to write to the DB
I get the following error :

The wierd thing about this is the connection strings work from the local machine when I run from Visual Studio and I can write to the DB there, I just cannot write to the DB from the URL.
I am pretty new to asp.net but I am sure it has to be something to do with the web.config.

I am trying to create a simple login page in ASP.NET C# but am getting some error.
I googled about the error, and tried all the solutions but to no avail.What am I doing wrong? The error is:

I think it's something to do with my connection string which is as follows:
<add name="cn"
connectionString="server=HCL;DataBase=GS;Integrated Security=True" />
"HCL" is another machine connected to my PC through the LAN and this database, "GS", resides on it. Is the problem with the value I am giving in "Server" attribute of the above code? If not what else may I be doing wrong?

View 2 RepliesWhen I load the asp.net config tool in vs2010 it loads the page up fine but as soon as I click on security I get the following error:-

There is a problem with your selected data store. This can be caused by an invalid server name or credentials, or by insufficient permission. It can also be caused by the role manager feature not being enabled. Click the button below to be redirected to a page where you can choose a new data store.
The following message may diagnose the problem: A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible.

My ASP.NET MVC 2 application runs under built-in local NETWORK SERVICE account. I want to set up access permissions for the folder which resides in another computer, but in the same domain. I located that folder right-clicked to open its properties form, clicked to Security tab and pressed Add button which displayed Add user form with correct domain name in the location field. I referred to the account with following syntax:
<domain name><server name>$
because I learned that NETWORK SERVICE account uses machine account when connected to other computers in the domain. However, the system couldn't find the account, so refuses to add the account. Without the domain name it adds a user, but that user seems to be local user, not web server's NETWORK SERVICE account. What am I doing wrong?
By the way, the above syntax worked when I created login for the sql server which is different computer from the web server.
i have a folder on the server which contains jpeg files,mp4 files and also xml files...........
i would like to transfer the folder to a centralised storage server ,i would like to pass the credentials from the web page itself,,,,,,,,
what do i use for it
the storage server is within the network and all it needs is credentials to copy the folder which i m ready to pass....but i dont know the code which has to be used......
whether to use system.io.move
or

I work from home and need to connect to my employers database server. I am running SQL Server 2008 on my home PC and I am connected remotely to my employers network via vpn. However, if I try to make a connection via windows authentication it's using my credentials I use to log onto my PC and not the credentials I use to connect via vpn. How can I enter my vpn credentials and register the remote server in Server Management Studio?
View 2 RepliesI inherited a web site that has a web page that displays images of properties for an online property/tax info. Using VB code, it searches for a main image then creates and saves smaller images for use as thumbnails. Currently it gets the images from a directory on the web server. The images are copied to the web server via a job from another server on our network. I am trying to code the page to get the images directly from the original server and having trouble doing it. Here's the code. Point of failure is indicated:

View 2 RepliesI am trying to create and write a file on a remote server using the below code:
[Code]....
but i am running into issues and getting errors. Below are some tries i have given. My IIS settings are 'Anonymous Access' checked and also 'Integrated windows authentication' checked.
a. As i understand asp.net site would run using ASPNET account, i tried giving full permission to ASPNET account to the folder on the remote server (where i want to drop the file). But i am getting this error - "Logon failure: unknown user name or bad password"
b. The other thing i tried is giving full permissions to 'Everyone' to the remote server folder. But i get the same error as above. But when in my web.config i enable impersonation by using:
[Code]....
then the error goes away and everything works fine as expected. The file gets dropped to the network share.
why the scenario (a) doesn't work because that should work as if i give ASPNET account full access to the folder, and my website is running under the same account, then it should work.
Also, in the scenario (b), i believe it is using my domain account, as the impersonation is true without specifying any username and password and also the remote server folder has Everyone access to full control.
BUT, as a security breach, i cannot use Everyone account to the remote folder. In that case, how can i make this working.
I was also thinking if i can use the virtual directory as the path to the remote folder, something like
http://domain.com/remotefolder but dont know how can i use this approach. Can someone pls share some sample code and the configuration.
I have the folloing sql server error from my ASP.NET website.

This seems to be a network related issue. But on the same machine where IIS is running, I have another C# application running that is not experiencing this problem. This happens after the website has been running for a few weeks. Will this be because the database connections are opened but not closed properly?. I wrote a test web page where i just open connection but not close it and I got Time out error when connection pooling is maxed out. Is this memory issue? Memory that are allocated are not deallocated in timely fashion?..
Everything is working fine for a few weeks and after that I get the above network error.
In my asp.net wep application i would like to move the folders from the server to a network location so that the server doesnt get filled up.
i was able to move the files within the same drive but not to other network locations .
