Exchange 2003 OWA Service Unavailable

Good afternoon everyone. I am having some difficulties trying to get OWA to work! Here is the scenario; Windows 2003 R2 Server, Exchange 2003 Server. Both are completely up-to-date as far as patches/SP's etc. The Exchange 2003 install is a month old, prior to Exchange being installed Novell Groupwise was on this particular server, but Groupwise was scrapped & Exchange was implemented. I cannot browse my Public folder via MS Outlook or the ESM. I have seen multiple posts all over the place pertaining to this type of issue. The Event ID's & such never match up to my particular problem though. The Event ID's in my System log pertiain to the the Default App pool & the Exchange App pool's being stopped due to multiple internal errors. The Event ID's that are associated with those errors are 1002 & 1039 W3SVC errors. If I try & view the "PF" properties via ESM then I get an ESM error saying the HTTP service used by the Public Folders is not available, possible causes are that the Public stores are not mounted and the Information Store service is not running. ID no: c1030af3 ESM. Something is definetaly going on with my App pools but I have no clue what it causing this! I have looked & looked. Any help would be much appreciated. Is there anyway to just remove IIS & then re-add it, via windows components, or would that totally hose OWA in the processes? Thanks again.

    If you are looking to re-install the IIS virtual directories, then you can try these instructions:,295582,sid43_gci1167561,00.html

    You can also use PFDavAdmin to check the permissions on the P:

    I actually stumbled acroos the first two links that you have there. This is the first time for PFDAVAdmin however & I was very excited while reading the document. But, when I try to run it I get the following error. "An error occurred while trying to establish a connection to the Exchange Server. It goes on to say to be sure that port 443 (for SSL) or port 80 (for non-SSL) can be reached. It bascially ends up saying that it Failed to connect via unsecure & secure URL's.  I am going to continue looking through things, my App pools keep stopping too. Grrr...

    I have spent a few more hours & have not resolve yet. There are a few items in the Event view they are as follows; System Log; Event ID: 1039 Source W3SVC Description: A process serving application pool 'ExchangeApplictionPool' reported a failure. The process id was '6024'. The data field contains the error number, the data is 0000: 7e 00 07 80 .. There are six of these errors, the process id's vary but the data remains 0000: 7e 00 07 80. There is an Event: 1002 as well & the description of this event is: Application pool 'ExchangeApplicationPool' is being automatically disabled due to a series of failures in the process(es) serving that application pool.
    Just to clarify, I should have done so in my above responce. I did remove all Virtual directories form IIS & removed the DS2MB referance using the MetaBase Explorer tool.. restarted the neccassary services etc. But I cannot utilize the PFDAVAdmin tool though. It's almost as though OWA is completly & utterly unavailable. When you try to browse to any OWA mailbox there is an error that states "Service Unavailable". Thanks again for your help, hopefullly we can shed some light on this tomorrow. Thanks!
