IIS6 Application Pool - Unspecified Error / Service Unavailable

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
Event Category: None
Event ID: 1021
Date: 12/29/2004
Time: 8:14:18 AM

Description:
The identity of application pool, 'Test Pool' is invalid. If it remains
invalid when the first request for the application pool is processed, the
application pool will be disabled. The data field contains the error
number.

Description:
A failure was encountered while launching the process serving application
pool 'Test Pool'. The application pool has been disabled.

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!

Re: IIS6 Application Pool - Unspecified Error / Service Unavailable

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

Re: IIS6 Application Pool - Unspecified Error / Service Unavailable

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

DRC
Alphabet collector (MCP,MCSD,MCSA,NECD ECT.)

Re: IIS6 Application Pool - Unspecified Error / Service Unavailable

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?

Drew.

Re: IIS6 Application Pool - Unspecified Error / Service Unavailable

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.

RE: IIS6 Application Pool - Unspecified Error / Service Unavailable

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

RE: IIS6 Application Pool - Unspecified Error / Service Unavailable

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

RE: IIS6 Application Pool - Unspecified Error / Service Unavailable

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

RE: IIS6 Application Pool - 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???
