Question

Trouble setting up IIS/ASP.NET development environment

Asked by: mdougan

I have Visual Studio Pro 2008 and I'm trying to work out a problem running the very first ASP.NET project I've created.

I've created a new Visual Basic project using the Web Application template and it created the Webc.onfig file as well as the Default.aspx file.

In the Default.aspx file, all I added was a Hello World!  In the body of the HTML that was automatically generated.

I've compiled the app, which lives in a folder under InetPub/wwwroot folder.

In the IIS Admin screen, I set up a virtual website to point to the physical folder, I set the permissions for that folder to allow reads and script execution, enabled Anonymous Access, and authentication is done through Integrated Windows authentication.  

Figured out that I had not installed Frontpage Extensions, so, went back and added those, and as far as I know, I've enabled them.  When I tried to navigate to my application through a browser, using a URL such as:

http://localhost/fb_feng_shui/Default.aspx

I first got an error about the user not having permissions to read the meta-something or another... which I was able to lookup and correct using aspnet_regiis -ga ASPNET

Now, I get the error below when I try to access the application directly through the browser.

However, if I enable debugging in the Web.config file and run it through the VS IDE, then VS navigates to it like so:

http://localhost:1114/Default.aspx

And that works perfectly.

Now, I'm just running this all on a stand-alone computer, connected to my home router.  I do have to login to my computer, so, I'm logged in as a local machine account, and there is no domaine controller... if that makes a difference...

Any ideas on how to proceed?  As I said, running it through the debugger doesn't generate the error, so, I can't figure out what is generating the error when not run through the debugger.

Did you run >aspnet_regiis -i ?

 

by: funwithdotnetPosted on 2009-02-02 at 15:02:40ID: 23532493

You shouldn't need Front Page Extensions unless you are using Front Page.

 

by: mdouganPosted on 2009-02-02 at 15:05:27ID: 23532517

No to the first question, but I'll try that.

I don't know if it is still the case, but under earlier versions of Visual Studio, the Frontpage extensions are also what controlled ASP.NET.  If you did not enable Frontpage extensions, then you couldn't run any ASP.

* By default Asp.net 1 is enabled for site in IIS... Check property for the folder configured and enable A
Asp.net 2.0 version and make sure that Asp.net 2.0 is enabled in Web Extenssion in IIS..

* Give Aspnet permission for the site ( folder)
* Assign Seperate application pool for this site with Identity Network Service.. ( IIS)

Yep, that did it.  As I said, I believe that in previous versions, ASP.NET was installed with Frontpage Extensions.  Using aspnet_regiis -i  invoked the install for ASP.NET and that solved my problem.  Thanks!

 

by: mdouganPosted on 2009-02-02 at 15:17:52ID: 23532615

Thanks everyone, the answer above solved my problem.  Didn't know you had to call aspnet_regiss - i to install ASP.NET

I did have to select ASP.net 2.0 for the folder, and that was another thing I'd done when setting up the folder permissions (forgot to mention that).

Couldn't find any place to enable Web Extensions in IIS for the folder... there used to be a separate folder in the IIS Admin console for Extensions where you could enable/disable them, but they don't show under this version.  All I could do was run a check on the Extensions which didn't generate any errors, just a question about whether I wanted IIS to tighten the security, which I delcined.

Never got to the last two items by servoadmin, but all seems to work now, thanks!
