Ever since I upgraded my computer from .NET 1.1 to .NET 2.0 I am frequently getting this error message when I try to access a website on my local IIS:

How can this be fixed?

Thanks

Did you set the site to the correct version of the framework?

Hi,

I have the same proplem...I got this message:

I would like to know how can I resolve it? how can set the site to the correct version of the framework...

Thanks,

First, do as the error tells you -- Look at the appliucation event log.  Setting the framework version is done on the ASP.NET tab of your web site in IIS.

Obviously I have Go Daddy involved as they say there is an issue with the ASP virtual instance and it has hung.  They also mentioned some potential code issues.  I have been
through everything and haven't found anything yet, but keep looking.  I hope to get the logs from Go Daddy soon.  Has anyone else seen tis or a similar issue?

July 19th 2006: 

Here is an update from Go Daddy as my issue appeared again after the moved my site to its own asp application pool.  They suggest this is a scripting issue where I am not
closing ASP objects (scripts and databases) after I am through using them.  As a newbie to ASP, I have no clue even where to start looking.

Any suggestions, thoughts or similar issues.  As a refresh, here are the site specs:

Generally, the Server Application Unavailable error, when associated with running two frameworks (1.1 & 2.0) side by side means that somewhere you are trying to run 1.1 apps and 2.0 apps within the same process.

Setup two separate application pools in IIS, one for 1.1 applications and the other for 2.0 applications.

Hello,

This problem of "SERVER APPLICATION UNAVAILABEL"  is arises due to Application pools, If we run two applications of different versions of asp.net under the same application pools then this problem occurs,

The solution is to create a seprate application pool and then run the second website which is developed in another version of asp.net under that pool.

The website that JEFF given provides a complete description about creating a seprate pool.

Bye and Take Care

If you installed 2 different versions of .net Framework then,

set the your site to the correct version of the framework...

Hello Chetan,

If u have two different version of .NET Framework then to run websites developed  under different versions then u have to make the different application pools else u can't run ur website with only setting the right version of framework for ur website.

With the setting proper version u have to develop the different application pools. 

Application pool is for the IIS 6 right? Theres no application pool for those who are using IIS 5. What is the solution for that? Upgrade to IIS 6?

Im using IIS 5 and I also got the same problem. What I did to solve this problem is I uninstalled the IIS and also the .Net framework, restart the PC and reinstalled IIS and the .Net framework. This seems very tedious work. But it works for me.

So anyone here got any other solutions especially for IIS5 developer ?
 

I have IIS version 5 where there is no option of add application pool what do I do in order to eliminate this problem. I have two versions of framework on my pc :( I am using windows Xp

can someone help me remove this problem pleases

U can follow my solutions. I also have 2 versions of .Net framework. But I use ASPNETVersionSwitcher to switch them accordingly.

 it's very clear

if u have a couple of virtual directories in two different frameworks that us the same application pool it'll cause this problem what u need to do is to make 2 application pools one for every framework and assign them to their respective virtual directories it's in the first tab that opens for a virtual directory properties window
