Hi,

One of my application (built in asp.net c# .net framework 2.0) is deployed in IIS6 in windows 2003 server. Recently I am getting the below error while accessing the application.

"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 have searched in google and as per the advise I got from many of the forums is to create a new application pool and deploy the application. I did the same but no luck.

Note: other applications which deployed in the same server, using diff application pool is workin fine.

Application pool identity is set to 'Network Service'


Can anyone please suggest how can I resolve this issue.

did you check this link

1 solution

Try the following in order to troubleshoot
1- Add an empty html file to your deployed folder and try to browse it from webserver
a. If you receive the same error, you might have some problem with permissions try the following link:

b. If it works means you have some problem with configuration or installed frameworks so in order to check the IIS configuration try the following :
•In IIS Manager, expand the local computer, and then click Web Service Extensions
•In the details pane, check the items and their ‘allow and deny’ settings
And last step could be registering .net framework in IIS, but I think it’s not your case, because you already have running applications in that IIS server with same framework.
