IIS is being really stupid - "Unspecified error"

I have IIS6 running on a Win2K3 box. It has been fine up until yesterday.
Prior to that the only configuration change I'm aware of is the installation
and subsequent uninstallation of SQL Server 2000.

When I browse to any of the hosted sites, I get simply "Service
Unavailable". When I go into the IIS manager, the Application Pools are
stopped with "unspecified error".

There are several different repeating kinds of entries in the logs in Event
Viewer. In the Application Log, there's:
=============
Event Type: Error
Event Source: W3SVC-WP
Event Category: None
Event ID: 2268
Date: 26/10/2007
Time: 10:42:15 AM

==========================



This has got me completely stumped. I have been searching for hours on
Google and found the following suggestions, none of which have worked:
*Changing the Identity of the application pool to IUSR_
*Adding the user to the IIS_WPG group
*Giving the IIS_WPG group, and Network Service, and Local Service, and
IUSR_ explicit permissions to access the necessary files
*Adding the users and groups to the "Act as part of the operating system",
"Adjust memory quotas for a process" and "Replace a process level token" user
rights
*Even giving the application pool my domain admin account to play with
*Running iisreset after trying each of these things
*Set up a new web site with one plain, basic html page to see if that causes
problems (it does)

I can reset the application pool and its status gets changed to "Started",
but as soon as I go to browse to the site I get "Service Unavailable" in the
browser and "Unspecified error" on the application pool.

There are several application pools. There's the default, which is used by
our websites, and several used by Exchange that I'm guessing are used by OWA.
All but one of them repeatedly gets the "Unspecified error".

I'm really desperate here. Any help is appreciated!

Re: IIS is being really stupid - "Unspecified error"

Well, it seems that the root of your problem is that the process identity is
invalid.

So the first question is: What identity are you using for the application
pool?

The next question is - what has changed from when it was working,to when
it's not working?

Re: IIS is being really stupid - "Unspecified error"

Thanks for the reply. I hadn't changed the account at all. Right now, its
identity is my domain user account. I have given it my domain admin user
account to play with as well and these made no difference, apart from the
fact that the warning event about incrorrect identity is no longer being
generated with the other log entries.

I hadn't changed the identity prior to this stuff-up at all. It was and
always has been using Network Service.

Re: IIS is being really stupid - "Unspecified error"

0x800700C1 with failure to load ISAPI Filter usually means that you
have configured an ISAPI Filter with the wrong bitness.

This usually happens on 64bit Windows, and occassionally on 32bit
Windows when user misconfigures with a 64bit ISAPI DLL.

Common ways to get into this state include:
1 Changing the Bitness of IIS6 (there's only three allowed values and
two states -- unset means the same as 0, and 1)
2 Adding an ISAPI Filter DLL of the wrong bitness

At this point, I cannot tell you which is the right answer. I suggest
that you toggle the bitness to see if it fixes things, and if not,
figure out the ISAPI Filter DLL that's failing and remove or find the
right bitness.

How to determine Bitness:
CSCRIPT %SYSTEMDRIVE%\Inetpub\AdminScripts\adsutil.vbs GET W3SVC/
AppPools/Enable32bitAppOnWin64

If it is not set or set to 0, change it to 1. If it is 1, change it to
0

How to set Bitness
CSCRIPT %SYSTEMDRIVE%\Inetpub\AdminScripts\adsutil.vbs SET W3SVC/
AppPools/Enable32bitAppOnWin64 0

For further explanation and other fun things with bitness, search my
MSDN Blog for "WOW64" and read.

Re: IIS is being really stupid - "Unspecified error"

Thankyou for the response. It seems you were right in that it has something
to do with the bitness. The problem is solved now, because I phoned the M$
support line and they eventually directed me to a KB article. Following the
particular sections the guy said to has solved the problem.

Thanks for helping out :)

Re: IIS is being really stupid - "Unspecified error"

Glad you resolved your issue.

Just trying to save you some $$ from having to call product support.
