How about making the applications that run on the server more stable? IIS6
tries its best to recover from user problems, but sometimes, it may not be
possible nor make sense, so IIS will disable the application pool to prevent
further server damage.
Seriously, you should not need to re-install IIS6 to fix the issue you
describe. Can you give the event log entry that says WHY the DefaultAppPool
is being disabled? Then, can you fix your application such that it doesn't
cause the Application Pool to be disabled?
A disabled application pool can be re-enabled by simply going to the UI,
selecting the stopped application pool, and changing it to "start". Now,
that says nothing about whether you could be running junk in the application
pool that makes it disabled again.
All IIS is doing is trying to run your application. If your application
misbehaves and triggers the many health-monitoring checks of IIS6, the
Application Pool gets recycled. When this recycle happens too many times
and too frequently, IIS stops the Application Pool to prevent any more abuse
of system resources. This is also a sign for you to fix your application or
maybe IIS configuration (perhaps your health-monitoring is too aggressive
for the application).
In other words, IIS6 is simply notifying you of potential problems and tries
to buy you some more time by proactively recycling the application to keep
it running. You should try to fix the problems, not shoot the messenger.
Fundamentally, it is impossible for IIS6 to keep a buggy application running
all the time, so the only real way to make the application more stable is to
remove the bugs in it.

Hi all, I got an error message this morning from my IIS 6.0 server. It seems the Default AppPool was disabled because it had something to do with the http.sys. To resolve this issue, I had to re-install IIS since it would not start the websites. I also configured an app pool for each website running on the server. I also disabled Rapid Failover and Pinging. Is there anything else I can do to make the server more stable ? thanks
