Question

ASP.NET environment setup issue

Asked by: peh803

I believe I'm having a setup issue with a .NET environment.

Here's some potentially useful background info:
- Windows Server 2003 / IIS 6.0
- The following directories exist in the C:\Windows\Microsoft.NET\Framework directory:
    1.) v1.0.3705
    2.) v1.1.4322
    3.) v2.0.50727
- I have full admin access to the web server in question and I am free to make configuration changes, recycle IIS, etc.
- I have added IUSR_[machineName] and IWAM_[machineName] users to the Administrator group just to make sure permissions weren't the issue here

I am trying (unsuccessfully) to install Microsoft's FlexWiki.  I have actually installed the wiki successfully on different servers, so I'm at a loss as to what's wrong in this case.  

When I try to view the wiki (localhost/flexWiki/default.aspx and any other pages) I get just a blank page -- no error at all.  

I found this towards the bottom of the following flexWiki help desk page: http://www.flexwiki.com/default.aspx/FlexWiki/WikiHelpDesk.html

"Q: I went through the steps in QuickSetup. When I navigate to http://localhost/FlexWiki/default.aspx I get a blank page. I also get a blank page when I navigate to http://localhost/FlexWiki/admin/config.aspx . In both situations the View->Source command is disabled so I don't have a way of determining whether this is really an empty page or a page that has bad HTML. When I navigate to http://localhost/FlexWiki/default.aspx/MyWiki.HomePage I get a 404 error. Has anybody seen this behavior before? What do you think is wrong with my setup?

A The problem in my case was that asp.net was not properly installed. I got a tip to run the following command to install it, and this fixed my blank page problems:

C:\WINDOWS\Microsoft.NET\Framework\v1.1.4322\aspnet_regiis -i"

I tried the similar command for v2.0.50727, restarted IIS, and I'm still having blank page issues.  Does anyone know of a utility I can run or some test I can do to see whether or not the ASP.NET runtime is successfully installed on my server or to further diagnose this issue?

>>does the event viewer show any errors?
No -- sorry, forgot to mention that ; thanks for asking.

>>Have you tried setting the framework version in IIS, for your site/virtual directory?
No -- somewhere in the properties of my virtual directory?

Thanks,

might sound silly...but is the virtual directory set up correctly?
when you right-click the virtual directory flexWiki in IIS and go to the Properties page, is there an asp.net tab?

 

by: peh803Posted on 2007-04-26 at 13:12:18ID: 18984780

Sorry -- yes, there is an ASP.NET tab, and the "ASP.NET version:" item has only 1 entry in it: 2.0.50727

The location for the web.config file is correct.

The directory is set up as an application in IIS (right click, properties, "Create" button under Application settings).

...you can't get to anything in your flexwiki install?
can you create just a super simple html page, put it into the flexwiki folder, and then see if you can browse to it?

like put this in notepad and save it as "test.htm" and place it in the flexwiki folder, then see if you can browse to it by going to http://localhost/flexWiki/test.htm

Strangely enough, when I try "http://server:port/default.aspx" in IE6, I get a blank page.  
When I try it in Firefox, I get:

   XML Parsing Error: no element found
   Location: http://server:port/default.aspx
   Line Number 1, Column 1:

When I navigate to "http://server:port/" in Firefox or IE6, I get blank pages.

Ideas?

 

by: samtran0331Posted on 2007-04-27 at 07:25:02ID: 18989230

ok...so that means the virtual directory is mapped correctly...
now...let's test if a simple aspx page works...put this in a notepad file called test.aspx and put it in the same flexWiki folder and see if you can browse to it...it should just load the time...
...I know it seems like silly tests...but without being there and only using this forum...I don't know of a better way to test things...
if this page loads ok...then we know asp.net 2.0 is running correctly on the server and IIS is setup correctly...and the problem is in the actual flexWiki installation and not server related...

Nope -- same result -- blank page in IE, the above XML error in Firefox.

I hope that means something to you!

Thanks,
Phil

 

by: samtran0331Posted on 2007-04-27 at 07:30:44ID: 18989284

ok...so the port number is a new bit of info...are you running the app in a port besides the default 80?

 

by: peh803Posted on 2007-04-27 at 07:33:33ID: 18989310

Yeah -- I've tried configuring it as its own website in IIS rather than just a virtual directory set as an application root -- same result either way.  

Interestingly enough, I can go to something like:
    http://server:port/pageDoesntExist.aspx
OR:
    http://server/appRootName/pageDoesntExist.aspx

And I get a blank page in IE, XML error in Firefox.

Arrrgh!

 

by: peh803Posted on 2007-04-27 at 07:34:38ID: 18989320

Obviously, the two pages above are references to nonexistent ASPX pages, in the event that the file name wasn't clear enough...

Are there any diagnostic tools to run against your current version of ASP.NET on a given server that will detect what's wrong with the setup?

Thanks,
Phil

 

by: samtran0331Posted on 2007-04-27 at 08:07:32ID: 18989610

http://server:port/pageDoesntExist.aspx
loads a blank page

and
http://server:port/test.aspx
doesnt work

but
http://server:port/test.htm
(our first html test page)
works?

 

by: samtran0331Posted on 2007-04-27 at 08:14:58ID: 18989686

i'm back to thinking that it is the asp.net components not being installed properly in IIS.
there isn't a diagnostic tool I know of perse besides aspnet_regiis...but usually running aspnet_regiis almost always clears up these types of problems...

aspnet_regiis has a lot of switches and parameters...and I"m betting one of them will get things going....
http://msdn2.microsoft.com/en-us/library/k6h9cz8h(VS.80).aspx

there are 2 switches that will let you see how asp.net is installed in IIS
"-lk" and "-lv"

maybe running those will give you some insight on whether or not asp.net got installed properly for the app....

 

by: peh803Posted on 2007-04-27 at 08:55:48ID: 18990075

Loads blank page in IE6, XML error in Firefox:
   http://server:port/pageDoesntExist.aspx
   http://server:port/test.aspx

Loads with no issues:
   http://server:port/test.htm

Thanks,
Phil

 

by: peh803Posted on 2007-04-27 at 08:57:02ID: 18990086

OK -- I will try some of the aspnet_regiis switches / parameters and post results ...

by: peh803Posted on 2007-04-27 at 09:08:14ID: 18990173

I am going to use -ua next:
   "Uninstalls all versions of ASP.NET from the computer."

And then try installing the ASP.NET redistributable once more (1.1 first, then 2.0 if 1.1 doesn't work).

thanks,
Phil

 

by: samtran0331Posted on 2007-04-27 at 09:54:11ID: 18990562

based on your "-lk" results...just to make sure...
W3SVC/1/ROOT/supportWiki/       2.0.50727.42
"supportWiki" ... is a different install of a wiki right?...it's not the one in question?

 

by: samtran0331Posted on 2007-04-27 at 09:56:14ID: 18990579

is flexWiki supposed to run on 1.1 or 2.0?

 

by: peh803Posted on 2007-04-27 at 10:28:54ID: 18990847

>>"supportWiki" ... is a different install of a wiki right?...it's not the one in question?

That's flexWiki.

flexWiki is supposed to run on both 1.1 and 2.0.

The one I've got working elsewhere is on 2.0, but was originally configured successfully to run on 1.1.  

 

by: peh803Posted on 2007-04-27 at 10:40:08ID: 18990943

OK -- some additional updates.

When I do -ua, of course it uninstalls all versions of ASP.NET, as promised.

Now the responses seem to be more reasonable:
   server:port/page.aspx -- "The request is not supported."
   server:port/nonexistentPage.aspx -- "The system cannot find the file specified."

I do -lk and -lv and it tells me that no versions of the ASP.NET framework are detected.

So, then I go to the Microsoft site and download the ASP.NET 1.1 redistributable (http://www.microsoft.com/downloads/details.aspx?FamilyID=262d25e3-f589-4842-8157-034d1e7cf3a3&DisplayLang=en) and try to install it.  It tells me that this version of the ASP.NET framework was already installed with the OS (Windows Server 2k3).  But I thought I uninstalled it?

At any rate, now I go back in to C:\NW2003\Microsoft.NET\Framework\v1.1.4322> and run aspnet_regiis -c, which says that it installs successfully.  

Then, trying the pages above give me the same errors as before.

Arggh!

I will try again with downloading and reinstalling the ASP.NET 2.0 redistributable: (http://www.microsoft.com/downloads/details.aspx?FamilyID=0856eacb-4362-4b0d-8edd-aab15c5e04f5&DisplayLang=en)

 

by: peh803Posted on 2007-04-27 at 10:41:47ID: 18990955

oops, error in my last statement.  I said this:

At any rate, now I go back in to C:\NW2003\Microsoft.NET\Framework\v1.1.4322> and run aspnet_regiis -c, which says that it installs successfully.

I meant this:

At any rate, now I go back in to C:\NW2003\Microsoft.NET\Framework\v1.1.4322> and run aspnet_regiis -i, which says that it installs successfully.

Note that I meant -i vs. -c (that's the only difference)

Thanks again.

 

by: samtran0331Posted on 2007-04-27 at 10:42:27ID: 18990960

>>But I thought I uninstalled it?
You didn't actually un-install the entire framework...you removed asp.net from IIS

 

by: peh803Posted on 2007-04-27 at 10:45:06ID: 18990981

I see -- good call.

What I'm doing now is running the Microsoft .NET Framework Version 2.0 Redistributable Package on the server.  When I executed it, it asked me if I wanted to repair or remove the one currently on the server.  I said "repair".

I'll let you know how that goes.

Thanks,
Phil

how many web sites are there in this IIS? do asp.net pages work in the default website at the default port?

 

by: peh803Posted on 2007-04-27 at 10:47:18ID: 18991002

It seems that *.aspx pages aren't working anywhere (application roots under default website on port 80 or other websites configured on different ports).

 

by: peh803Posted on 2007-04-27 at 10:49:25ID: 18991018

I've completed the repair, and now I'm back to the ol' XML error:

by: peh803Posted on 2007-04-27 at 10:58:06ID: 18991069

Still the same -- I will now try to uninstall ASP.NET 2.0 and then try to reinstall it.

 

by: samtran0331Posted on 2007-04-27 at 11:00:11ID: 18991083

>>I put the same test.aspx (from before in this thread) in wwwroot and tried to access it through the default website on port 80

That test page will only work if it is in a place (root or virtual directory) that is defined as an application and has a web.config file...and running net2.0 ...

 

by: peh803Posted on 2007-04-27 at 11:02:20ID: 18991097

ok, good to know.. will just try it within flexWiki's root directory (defined as an application with web.config file, etc.)

Thx...

 

by: peh803Posted on 2007-04-27 at 11:33:08ID: 18991306

hmm, after uninstalling ASP.NET 2.0 and reinstalling it, I get the same thing (XML error in FF, blank page in IE).

I seem to be running in circles.  Any other ideas?

 

by: samtran0331Posted on 2007-04-27 at 11:53:30ID: 18991431

all I can think of is a corrupt IIS metabase...and regardless of what the diagnostics tell you...asp.net is definitely not installing correctly into IIS

and since you've installed flexwiki before without problems...it makes sense that the issue is at the web server (IIS) level and not anything with the installation of flexwiki...
99% of the time i've had problems getting asp.net to run, aspnet_regiis takes care of the problem...that other 1%...

sadly (and don't hate me for this)...I had to un-install IIS completely...ran some registry cleaning tools...and did a re-install of IIS and then ran aspnet_regiis

with all the things you've tried...I"m guessing this isn't a production server...a re-install of IIS is all I can think of ...there are ways to try and repair the IIS install...but it might just be easier to start fresh...

 

by: peh803Posted on 2007-04-27 at 12:08:51ID: 18991539

arrgh!  How about I try another server? :-)

Ok -- so I've tried another server, and I notice when I right-click on an application root or a website in IIS 6 and hit properties, I don't see an ASP.NET tab.

However, I did run aspnet_regiis -i on directory v1.1.4322 on this server and it said that it completed successfully.  

Why wouldn't the ASP.NET tab be there?

Thanks,
Phil

it's been a little while, but if I remember correctly, the asp.net tab in IIS wasn't added until 2.0 came out

1.x by itself didn't have this tab...

again...it's been a little while..and I can't find a web server on our network that is running only 1.x to verify...but i'm about 90% sure this tab wasn't there if your web server is running only 1.x

Ah, well that would make sense then.  I haven't tried upgrading this other server to 2.0 yet --  Thanks for the tip.

@samtran0331:

I have not pursued this issue any further, mostly because I didn't want to totally rip out IIS and reinstall it on either of these two servers.  However, you've been immensely helpful and I really really appreciate it.  I am confident that reinstalling IIS would resolve the issue, so I am comfortable awarding points for that recommendation.

Thanks again for all your assistance with this, and I apologize for the delay!

Best,
