Service Unavailable Error Message When You Browse a Web Site
 
When you configure your IIS webserver and find the following message

Service Unavailable

Then the first solution to the above error is http://support.microsoft.com/default.aspx?id=823552 but if this does not solve the problem try doing the following stuff.

Open the IIS Manager, right click Web Sites and select properties:

Switch to the Service Tab

Check "Run WWW Service in IIS 5.0 Isolation Mode".

You will be asked for Restart of IIS. Click yes to restart IIS. If you are not asked just restart IIS.

This solved my problem which occurred after installing VM Server. My question is what does isolation mode really do and why did it fix the problem?

This means you will not be able to take advantage of worker process isolation and the other features of worker process isolation mode.

I am getting the service unavilable error in the interval of 3 to 6 months. the application is created using asp and oracle.
i can see the following error in the event log.

Error:

Application pool 'application name' is being automatically disabled due to a series of failures in the process(es) serving that application pool.

can anyone tell me where is the problem? my application side or iis6 server side?

Can you clarify what you meant by 3 to 6 months.

Understand and Diagnose an Application Pool Crash would be good place to start off.

Hi shabbir,

Thanks for the valuable reply,

According to that article, we have to install debugger for find out the error that will happen in the next time. I can understand, but my question is whether my application may cause this error or not? if it is so then i have to check my asp pages for infinite loop,syntax errors..etc.But it is a very standard application and running for more than 4 years without problems.
Please kindly guide me.

Regards,
Kalees

The cause of the errors cannot be from the program. It just the problem from the installation or configuration point.
