Server Application Unavailable-No application Event Log

I have a Windows 2003 Server Web Edition running an ASP.NET application. Every so often (maybe once every day or two) when I try to get to the site I will get the following error: 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. However, when I go into the server's event log, there are no events related to IIS, ASP, or anything. No web related events whatsoever. If I stop and restart the WWW Publishing Service, the site will come back up. I've searched for other people having this problem and I haven't seen anything that's similar to my situation...does anyone have any suggestions? Thanks.

Hi, Just check whether the application pool is having some problem and gets blocked down after some time. If you go to the virtual directory, right click on it and select properties, you will see the application pool drop-downlist. Check out the application pool which is listed there and check whether it has some problems. I think this could be the problem.

Re: Server Application Unavailable-No application Event Log

Hi, Thanks for your response...I've looked and it's using the default application pool. I really don't know anything about application pools, so I'm not sure how to tell if it's having problems. Is there something special I should be looking for? Thanks.

Re: Server Application Unavailable-No application Event Log

Hi in the IIS, Click on Application Pools. You will be able to see the available application pools. Check to see if the Default applicaiton pool is running or its state is "stopped" unspecified error. Check and let me know so that we can diagnize. Thanks.

Re: Server Application Unavailable-No application Event Log

The default application pool is running. No errors are being shown. Thanks.

Re: Server Application Unavailable-No application Event Log

This morning I got the same error when attempting to run my web application. Before I restarted IIS, I went and looked at the application pools and there is no indication of any problems (they are all running). There is nothing in the event log relating to IIS, application pools, ASP.NET, etc. Does anyone have any suggestions of where I should continue to look? I'm kind of in a bind here and I don't know what to do next. Any help is appreciated. Thanks.

Re: Server Application Unavailable-No application Event Log

I am experiancing this difficulty as well. After restarting Windows Server 2003, ASP.NET will not function, but restarting IIS fixes this for several minutes.

Re: Server Application Unavailable-No application Event Log

Hi I am having the exact same problem. My asp.net applications will work for a day and then they suddenly go down. I too do not have any error messages in the event viewer and the application pool seems to be ok. (However, everything is running right now, but I'm sure that tomorrow I'll have yet another Server Application Error greeting me in the morning and so I'll check it then.) When everything goes down regular ASP still works and everything is normal with the exception of my .net stuff. I've been snooping around in the application pools and it appears that all of my applications are in the same pool and so I'm figuring that's why they all go down at the same time. So perhaps it has something to do with that, but if not then I'm at a complete loss as to what's going on. Someone please help us! Thanks. Kylir Horton

Re: Server Application Unavailable-No application Event Log

Odd times I guess. I am getting this on my local dev box as well. I DO have an error in my event log that I found on the ms site. It recommends some registry edits/manual permissions settings, etc... I am not to keen on fiddling with my box this way. Thoughts?

Re: Server Application Unavailable-No application Event Log

Hey guys, I think that I may have fixed the problem with my particular problem. I noticed that when I got this error message that ALL of the asp.net applications went down simultaneously. I thought that to be strange and concluded that the problem wasn't with any one of the programs specifically. So I looked at my application pools on IIS. I noticed there that all of my applications were in the same pool (DefaultAppPool). I created some new application pools and moved my most important applications into them so as to seperate them from others that could be causing problems. I did that about a week ago and since I haven't had any problems whereas before it was crashing daily. Perhaps try doing something similar to this? mbowles, I think that you may have a different problem from the rest of us. None of us ever got any error messages in the event viewer, which I'm guessing means that something happened within IIS. Good luck! Kylir

Re: Server Application Unavailable-No application Event Log

A few days ago, I decided to use three worker process under IIS 6. If a page says "Server Application Unavailable," just refresh the page and it will usually work. But a real solution to this problem would be nice.

Re: Server Application Unavailable-No application Event Log

I had the same problem running ASP.NET version 2 Beta 2 under windows XP professional.

I found that the 'Cache ISAPI applications' option in IIS on the 'Home Directory' tab under 'Configuration' must be enabled.
