IIS - IIS 7 Running 32 bit app in 64bit server

Asked By joe90bas

Hi,

I'm trying to get a new helpdesk applicaiton running on IIS7 on Server 2008
std 64 bit, currently the server runs Exchange 2007 and our Intranet and
external site (I know not best practice but circumstances dictate!) Exchange
is sitting on the default website, with a separate site for the external
website with the Intranet sitting under this site and the helpdesk under this
- all is well and the helpdesk works apart from the e-mail polling which
requires a 32 bit application pool in IIS.

I have tried setting the Intranet application pool to 32 bit but it also
turns the default website pool into a 32 bit pool which kills OWA :-( I've
trawled the Internet and all the guides I find suggest doing exacly what I've
tried. Am I missing something obvious?

Thanks

Chris

Hi Chris,

I'd suggest you follow the steps below to try again:

1. Create a new application pool for the helpdesk application.
2. In the new pool's advanced settings, set Enable 32-bit Applications to
true.
3. Right-click the helpdesk application's virtual directory in IIS manager,
make sure it has been converted to application. This makes it be a separate
web application which is independent to the parent site.
4. In the virtual directory's Basic settings, change it to use the new
application pool.

If any problem still persists, please let me know.

Have a nice day.

Sincerely,

WenJun Zhang

Thanks,
I'll try these steps tomorrow. We've had a few inches of snow today and as
always the UK grinds to a halt and the school I work at is closed!

What I'm puzzled at is the default website, external website and intranet
are separate applications using separate application pools, so why does
changing the intranet pool to enable 32 bit applications automatically change
all the other pools as well?

Thanks

Hi Chris,

I also think it's an unexpected behavior and cannot reproduce it on my
64bit Windows 2008 machine. Anyway, please try the steps and see if the
problem no longer occurs. If it still persists, we should perform further
investigation.

Thanks.

Sincerely,

Morning!
I can confirm that creating a new application pool, and setting it to enable
32 bit applications sets all other application pools to true for "enable 32
bit applications".

Hi Chris,

This is really unexpected behavior. So far I haven't heard anybody else
reported the same issue. Probably reviewing your server's config file will
give us some clue on this. Would you please send your
applicationHost.config in System32\inetsrv\config to me via email?

My email address: wjzhang@online.microsoft.com (please remove online.)

I look forward to your message.

Hi,
Thank you for the suggestion via e-mail. I have tried the config adjustment
but still no joy. The entry for the application pool in question is now as
follows:

managedRuntimeVersion="" managedPipelineMode="Classic">
loadUserProfile="true" />

It still shows as enable 32 bit applications 'false' and the helpdesk e-mail
poller still does not run.

It's a mystery!

Hi,
I have made the suggested change (as below), however the heldpesk e-mail
application still does not run - the enable 32 bit application is also still
showing as false in IIS manager
managedRuntimeVersion="" managedPipelineMode="Classic">
loadUserProfile="true" />

It's a mystery!

Solution - in case it helps anybody else........

Right clicking the application pool and choosing set application pool
defaults does just that! It isn't just for the app pool you right click
on......

Thanks to WenJun for his help with this, my error was only spotted when I
was in an EasyAssist session with MS product support. I feel a bit better at
being told that the support professional made the same mistake when he first
used IIS7!!
