OWA not working - page cannot be displayed

please check if iis services are running, please try to run iisreset and check after that from exchange server

All Exchange services are running. I did the IISRESET but this did not fix the issue.
When I go into ESM and look at Status I get a notification for Critical for my server, even though all services are running. Not sure if this has anything to do with it.

first thing to do is reset the virtual directories as per: http://support.microsoft.com/kb/883380
I use method 2 but others use method 3.

I checked permissions per Narayan's post and made the changes below, did an iisreset and this did not fix the issue. Although - I do not have an "exchange-oma" website. Is this an issue? I am going to try method 2 from the KB now.
added integrated to default website
removed integrated from exchange website
removed anon and integrated from RPC - added basic + ssl  
thanks,
Bobby
 
 

Exchange-oma is not created by default it is just for ActiveSync when you have FBA enabled so no need to wory about it.... not related to OWA at all.follow the method 2 of Kb 883380 and see if it works

Ok - i followed method 2 of the kb all the way through and the issue still persists. what should i try next?

Can you get OWA from your exchange server if on the exchange server you browse to http://localhost/exchange ?

If not what error do you get?

What about just browsing just default website open IIS and right click on default website or open IE and just type localhost
see if you get the IIS page Under construction.

I tried http://localhost and http://localhost/exchange and both come up as "The page cannot be displayed".
"The page you are looking for is currently unavailable. The Web site might be experiencing technical difficulties, or you may need to adjust your browser settings. "

open IIS manager goto exchange directory right click and say browse
please let us know what error message it gives

Same - The page cannot be displayed

is it asked you for credential. and after providing credential it has given "page cannot be displayed"

I would remove and reinstall IIS as per: http://support.microsoft.com/kb/320202

make sure you follow the steps exactly.

do we have any logging enable please check Httperr.log.

please be aware reinstalling IIS would break exchange and you have to reinstall exchange after you reinstall IIS

it does not ask for my credentials. well that sucks - i guess there is no way to fix it without taking down Exchange at this point??

But its sounds logical to reinstall IIS and then exchange as suggested by our friend demazter

The document improvised a link for explains how to remove IIS from a server that is running Exchange, that's why I posted that link!!

Maybe you should read it before knocking it?

My previous comment was not aimed at you author!

No problem - I appreciate all the comments. While waiting until tonight when I can re-install IIS I am looking at the other posted KB: http://support.microsoft.com/kb/934878.
I actually do have the /3gb switch in the boot.ini and the connections refused errors in the HTTPERR log described in the KB.
I added the aggressivememory key to the registry and restarted IIS. OWA is now working internally - if I go to IIS Admin I can browse to the site and login.
It is not working externally or from PDA's - could this be a permissions issue?
 
Thanks,
Bobby

I took screenshots of the results and have attached them...

Can you try these trouble shooting steps: http://support.microsoft.com/kb/330463

I had to add Integrated authentication back to the Exchange website per the suggestion on the connectivity test website and now the issue is completely resolved.
Thanks everyone for your help I really appreciate it !!!!!!!!!!!!!!!!!!!!!!!!!

Thanks!
