IIS6 Application Pool - Unspecified Error / Service Unavailable

[Colin Bowern]

Can't seen to figure out why the server is returning Service Unavailable to
the web browser and Unspecified Error for the application pool. It is using
a domain user account (member of IIS_WPG, temporarily added to Domain Admins
/ Administrators) and IIS is running on a domain controller. My event log
is outputting three errors in the system log:

---
Event Type: Warning
Event Source: W3SVC

The event log and error messages seem rather vague and silly in my opinion.
I have been through KB article 812614, REGMON, FILEMON, and other tools with
no luck. Any thoughts?

Thanks!

I seem to have resolved the issue by recreating the application pool account
(delete / recreate). Still not sure of the root cause.

Hi,
You need to get into the local policy (in mmc add the group policy of
the local machine snap in)
and then go to Computer config/windows settings/user rights assignments
and add under Act as part of the operating system, what ever user id
your using to start the application pool

I've been encountering the same error. I have added the Domain account
into "Act as part of the operating system", have added the user to the
iis_wpg, and even created a brand new pool to test this on, etc etc. I
still get the same error. With one domain user (mine) the pool runs
fine; with the one set up especially for this application/system, the
pool errors out. I am told the only difference in these IDs is that
mine has expiry passwords and the 'system' one doesnt, and that the
'system' one has to be granted permission to the devices on which it
will run (which I'm also told it has).

Anyone have addtional ideas I can try?

FWIW, I'm also having the same trouble. I've also added the domain
account (both mine personal account and a non-expiring "faceless"
account) into the "Log on as a service" group in the Local
Policies/User Rights Assignment. No luck. I still get the exact same
event log and the pool gets disabled.

You have to add the user to the IIS_WPG user group. It should work then.

Adding the identity account to the iis_wpg group fixed me right up. Thanks!

In our case the Application Pool Identity Users password was reset on the Domain but not retyped into the Application Identity settings. see this article. http://support.microsoft.com/kb/931507

Listen Everyone, I was facing the same problem and what I found on this discussion were only workarounds but there was no one to answer the real cause of this problem.

The real cause of the application pool not starting is that you Application pool account's password has either changed or the password has expired.

First Step findout your application pool UserID
Go to IIS:
Check the Identity Tab for your application pool account(leave those application pools where the app. pool identity is predefined ). In my case my configurable UserID was MOSS and the password of this UserID had expired. In your case the UserID can be different.

Second Step reset the Application pool Userid's password
Goto Active Directory:
Its possible that someone else might have changed the password for MOSS ID, or based on policy password might have expired.
So now change the password for MOSS UserID as it is your application pool ID.

Third Step
Goto IIS Again:
For ALL application pools go to the identity tab and next to your Application Pool UserID (ie MOSS in my case) write the new password.

Due to some problem the password changed and it is not updated in IIS automatically so IIS is unable to start application pools, start throwing Unspecified Error / Service Unavailable.

Hi, I've just been reading this thread, as I am facing the same problem on different servers within an IIS farm (24 in total). the root cause seems to be a password expiry issue. However, I checked the Identity settings for the AppPools, they are all running with "Network Service" account.

Any thoughts on this one???

Hi Steve,

Have you discover what was the problem? I'm having the same problem, I did everything and nothing ...

1.) Make sure the user password is correctly entered when assign the user into application pool identity, then stop the pool and start the pool.

Check the IIS User Id and Password, this error occured sometimes changes administrator password changed or expired. Start IIS - Application Pool - Right click - Proprities - Identify Tab -- check user id and password or retype the current user id and password in the Configurable option selected. Finally Restart IIS.

unfortunately, I now have this problem too. however, I've tried all of the
suggestions and nothing works.

I'm thinking this happened due to an MS update coming in over update center
last night...

please let me know if anyone else has this issue and finds a different
solution for it...

There are infinite ways to get "Service Unavailable" on a web server.

You have to diagnose the cause of the issue to determine the
corrective action. If you do not know the error code from the event
log that caused your "Service Unavailable", then you have no chance to
solve your situation by searching and trying random "solutions" on the
web.

Remember, there are infinite ways to get this issue, and you cannot
try infinite solutions to resolve it. Asking for different solutions
is pretty much waste of time because there is no guarantee that
someone's solution to their problem is the same as your problem; you
could have different problems that result in the same "Service
Unavailable".

You have to diagnose the issue and then resolve it.

When IIS returns "Service Unavailable" there WILL be event log entries
detailing what happened to take the IIS Application Pool offline. You
have to look at those event log entries and take corrective action.

For example, if the application pool has a custom user/password which
expired, that will cause the Application Pool to fail to start up and
hence result in "Service Unavailable". That unique error code will be
logged in the event log on failure to start up, which is what tells
you to synchronize the password.

I had the same kind of problem when I try to use a different application pool with different credentials. Adding iis_wpg solved the issue. Thanks a lot for the tip.
