Server Application unavailable error

[Guest]

I have set up a virtual directory using IIS. Whenever, I load a web page of
type .htm, I have no problem. Whenever I run a .aspx page I get the statement
below. I am running on XP Pro, both Microsoft .Net 1.1 & 2.0 installed. How
do I remedy this error?

//Error below

The critical part of the error message is this :

!> Failed to execute the request because the ASP.NET process identity
!> does not have read permissions to the global assembly cache.

Are you impersonating the ASP.NET identity ?

You are running on XP.
XP's default ASP.NET identity is the ASPNET account.

run :

aspnet_regiis -ga machinename\aspnet
( substitute *your* machine's name for "machinename"... )

....from a command window in the .Net Framework 2.0 directory :
Drive:\WINDOWS\Microsoft.NET\Framework\v2.0.50727

I'm not sure if you can get away with running just :

aspnet_regiis -ga aspnet

That should get you up and running again.

I did all you told me to do and the problem persists. This is the error
event log data. It seems the same as shown below.

I suspect you fumbled the command which gives *any*
account *all* the permissions ASP.NET needs to run.

In spite of that, Try to give access permissions to
the ASPNET account to the GAC directory itself.

The GAC directory is Drive:\WINDOWS\assembly

 

[Guest]

Not sure of the steps to this. Could you enumerate the steps. Thanks

re

The best way to approach this, since you can't set the access permissions
to the GAC directly, is to annul and recreate the ASPNET account.

To do that, run, from a command window in the .Net Framework directory:

aspnet_regiis -u

and, immediately after that, run :

aspnet_regiis -i

That will, first, annul the ASPNET account and, then, recreate it,
assigning all necessary permissions to all the needed directories,
including the GAC.

Still does not help. I'm thinking of re-installing IIS, ASP. Net and Visual
Studio.

 

[Guest]

I am so, so so, ahhhhhh. What is wrong? I can't believe that I've spent the
better part of 4 days trying to figure out this without success. If Apache
could have done it I would have switched long ago. I've been using Apache and
PHP for years and no problem to configure the web server. This is my first
try at using ASP.Net. When I check the Internet, I see a plethora of
questions about the same issue and there seem to be so many ad-hoc
patches/solutions. The only thing I see on Microsoft site which resembles my
problem, has to do with problems in ASP.Net 1.0 issues. I have not seen any
solution to ASP.Net 2.0 problems. If I had not invested so time and effort in
this I would toss all this .net technology aside.

 

[Juan T. Llibre]

On your first message you said that the problem
is with *one* of several ASP.NET applications:

!> I have some asp.net applications running on a IIS server. No problem.
!> This morning, i wanted to start an asp.net application, but i get the error:
!> "Server Application Unavailable; the web application you are attempting to
!> access on this web server is currently unavailable.

Can you run *any* asp.net application on your IIS server ?
Or, does the problem extend to *all* asp.net applications ?

 

[Guest]

Actually, I meant 1 application. I have never been able to run an ASP.Net
from IIS application only using VS 2005.

 

[Juan T. Llibre]

If that's the case, it's a good assumption that you have a bad install.
Nuke ( fully uninstall ) IIS and the .Net Framework.

"Start", "Settings", "Control Panel", "Add or Remove Programs".

The .Net Framework 2.0 removal icon should be visible
when you open "Add or Remove Programs".

You can, afterwards, uninstall IIS by clicking "Add/Remove Windows Components".

Then, after rebooting, install *first* IIS, and then the .Net Framework 2.0

Please postback your results.

No change. Do you think I need to re-install from the OS? That is what I've
seen in some newsgroups. I notice that if I try to use Firefox to access
localhost/mysite, I am being prompted for username and password. That is not
the case with IE6

 

[Guest]

Hi,
You have mentioned that both .NET 1.0 and .NET 2.0 are installed .So
probably both ASP.NET 1.0 and ASP.NET 2.0 are installed on your machine.If
that is the case then you need to tell IIS which version you want it to run
with.Steps for these are:
The ASP.NET MMC Snapin is integrated into the IIS MMC administration tool.
To use the snapin, use the following steps:
[1]Open the IIS MMC console, by using Administrative Tools/Internet
Information Services.
[2]Select the application or directory you want to debug, and select
Properties from the Action menu.
[3]From the property sheet, click on the ASP.NET tab.
On this tab, you can review or change the ASP.NET version used for the
current application. Any change you make to this setting applies to all child
applications.
from this tab you can change version to 2.0 or 1.1.
However I wanted to make sure that if you are using IIS 6

Dave,

I was plagued by this exact error as well as "Access Denied" errors until I
figured out the file encryption software my company installs as part of our
standard image was causing this.

I am surprised that you say you uninstalled IIS and the .Net Framework,
and reinstalled them both, in only the 1 1/2 hours that passed between
my suggestion and the time you reported that implementing them didn't work.

Are you *sure* you followed my suggestion *exactly* as explained ?

It's impossible to uninstall/reinstall *both* IIS
*and* the .Net Framework in less than 1 1/2 hours.
