Hello Bolwerk,

Hello

I got a client who uses what appears to be ASP.NET 2.0. I come from a
UNIX/PHP/Apache background, and I'm not too familiar with ASP.NET. He
had some permissions problem a few weeks ago that I managed to fix.
Now, he's getting this error (similar to the one a few weeks ago):

Server Application Unavailable
The web application you are attempting to access on this web
server is currently unavailable. Please hit the "Refresh"
button in your web browser to retry your request.
Administrator Note: An error message detailing the cause of this
specific request failure can be found in the application event
log of the web server. Please review this log entry to discover
what caused this error to occur.
I'd actually likely be able to figure this out on my own if the
administrator note were correct, but I can't find anything in the
event log about the issue either. Trying to run the application over
and over produces no record of a problem in the event log.

The configuration is Windows 2000, with .NET 2.0 the default ASP.NET
runtime environment. He uses IIS (I'm guessing version 5, but I'm not
even sure where to look).

There were some application events earlier today:

aspnet_wp.exe could not be launched because the username and/or
password supplied in the processModel section of the config file
are invalid.
I see nothing about username/password in the processModel Section of
that file, which appears to be:

C:\WINNT\Microsoft.NET\Framework\v2.0.50727\CONFIG\machine.config

The process model tag seems to concist of:

<processModel autoConfig="true"/>

Another event:

aspnet_wp.exe could not be started. The error code for the
failure is 80004005. This error can be caused when the worker
process account has insufficient rights to read the .NET
Framework files. Please ensure that the .NET Framework is
correctly installed and that the ACLs on the installation
directory allow access to the configured account.
I also changed the ASP.NET state service to run on a local system
account instead of some ASPNET account. I'm not even sure what the
hell the ASP.NET state service does, so maybe I shouldn't even have
monkeyed with it.

I'm noticing that a few versions of ASP.NET appear to be installed
concurrently. 1.0, 1.1, and 2.0 as far as I can tell.

Any suggestions about to fix this would be greatly appreciated, or
even URLs in the right direction.

Thank you!

Look at the user that is configured in the application pool. You can
find the application pool in the properties of the website and/or
virtual directory that contains the site you're trying to get to run.
Then in the Applications tree look at the properties of that specific
Application Pool. One of the settings is the username to run it under.
That user must have permissions on quite a few folders to get things to
work.

1) Read/Execute on the framework directory
(c:\windows\Microsoft.NET\%Version%)
2) Read/write rights in the ASP.NET Temporary Files under the framework
directory
3) Read/write rights in the system temp directory (default under
c:\windows\temp)
4) Read/Exeute permissions on the folder containing the website
5) maybe even more, but this is all I can think of for now...

Hey, thanks for the response, but I don't see anything about an
application pool. Is that an IIS 6.x feature? I think I have IIS 5
here. :|- Hide quoted text -

State service most likely is not necessary.

Check the ASPNET account in the operating system security and make
sure the account is not disabled.

If the .net app is using impersonation, look at what user it is mapped
to in the app's web.config file, and then check that in the os
security as well and make sure that isn't disabled too. A lot of our
customers do the latter and don't realize that their 'user password
expire every X days' actually bombs the web app after X days pass and
the account disables.
