Web Forms :: Can't Get Image From Network Server
Oct 21, 2010
I 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:
[Code]....
The server error: "Parameter is not valid." How can I get this to work?

I've got a ASP.NET site that's located on a local server (MY_SERVER). And one of the things it does is pull up tiff files which are located on another server (ANOTHER_SERVER). The location of each of these files is stored in SQL. I pull up each of these images and am supposed to display them. The problem is:
the files are not named with a tiff extension (does it matter?) they aren't displaying at all.
I am using an Image control to display these images, and I'm not sure if it matters that the extension is not set (does the image control know the difference between an jpg and a tiff without the extension?)
I am guessing the images aren't displaying because they are not on the same server MY_SERVER that the images are located (ANOTHER_SERVER).
edit: actually displaying the tiff files were amazingly simple:
protected void Page_Load(object sender, EventArgs e)
Response.ContentType = "image/png";
new Bitmap(Request.QueryString["ImagePath"]).Save(Response.OutputStream, ImageFormat.Gif);
}
but because the images are located on ANOTHER_SERVER I still can't access them. I may just do a hack where I copy them to a local directory on MY_SERVER but there's gotta be a simple way to fix this. Anyone?

I have an Image control with the ImageUrl property set to point to an image on a network folder, the address looks like this:
\fs01PRODUCTSimagesAM101.jpg
It renders correctly in IE but not in Firefox.
pasting the url/path directly into the browser, the address is maintained in IE: \fs01PRODUCTSimagesAM101.jpg
But in Firefox, it is converted to this: file://///fs01/PRODUCTS/images/AM101.jpg
I suspect this is related to the problem.

I 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 load balanced web servers My application has a function that allows the user to upload their company logo to display in the application header obviously, when they upload the logo image file, it needs to be in a central location or otherwise, the file will not be accessible to the other server on the load balancer. in order to be able to upload the image through the application other one of either servers and then display it on both servers I need a virtual directory on both servers that point to a third "file server" (this is the "AcctData" directory shown below with a sub folder "images")
If I use pass-through authentication I get a 401 error. If I use a specific user that's set up on both boxes, I get a 500 error. I've also tried sticking a Web.config file in the "AcctData" directory allowing anonymous access.

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:

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'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:
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: 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
name="ApplicationServices"
connectionString="data [code].....
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 have the folloing sql server error from my ASP.NET website.
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)
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.

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?
