Server Application Unavailable

I am using IIS 5.1 with ASP.Net 1.1.4322. About once a month I get the error above when trying to open a web application. I used to fix this with fiuxup cmd, but that does not work anymore.

Here is the error in the application log:

Aspnet_wp.exe could not be launched because the username and/or password supplier in the processModel section of the config file are invalid.

I've never changed the config log. Here, I think, are the relevant entries:

processModel Attributes:
enable="[true|false]" - Enable processModel
userName="[user]" - Windows user to run the process as.
Special users: "SYSTEM": run as localsystem (high privilege admin) account.
"machine": run as low privilege user account named "ASPNET".
Other users: If domain is not specified, current machine name is assumed to be the domain name.
password="[AutoGenerate | password]" - Password of windows user. For special users (SYSTEM and machine), specify "AutoGenerate".
logLevel="[All|None|Errors]" - Event types logged to the event log

What is this error telling me? How can I fix it?

Many thanks

Jeff,

Many thanks for your help - I am still going in circles on this one. The main thing I would like to learn is what changed with my computer, IIS, etc between yesterday and today. The processModel in my machine.config file was commented out yesterday, and everything worked fine. Today it is still commented out, but I get the error, so so much for the MSFT fix.

What mainly worries me is that there is some process going on behind the scenes which is creating changes I am unaware of. This app has been runnig for a couple of years now, but this problem comes up periodically.

It makes me very skittish about deploying MSFT flavor web apps - they seem to work one day then not the next.

At any rate, thanks for the pointer.
