OWA will not work on Exchange 2003, shows red crosses and no icons

I recently installed Exchange 2003 on a Windows 2003 Server. The server is on SP2, Exchange is on SP2 also. All was well for a few weeks as far as Outlook Web Access is concerned until recently. Now OWA simply loads up a load of big icons with red crosses in each of the boxes and will not show you any messages. Everything else on the server works fine, all clients on local Outlook 2003 work fine.

It matters not what machine I try and log on to OWA from, still the same, even on the server itself.

The only thing I can assume that has happened is that someone else has loaded another application (Autodesk Vault Manager) which has made some changes to IIS in some way to throw out the OWA.

I'm not sure where to start.

I have done all of the bove to no avail. All the directories in IIS have re-created themselves, I've checked permissions etc and all seems ok. Then I restarted IIS and still just get big blue boxes with red crosses in them.

Data loss can hit a business in any number of ways. In reality, companies should expect to lose data at some point. The challenge is having a plan to recover from such an event.

Not sure if this helps, but if I click on one of the icons with a cross in the box I get error on page, the details of which show:
Error:Object Expected

Not sure what this means but I'm sure its relevant to the problem.

Just solved the problem myself:

F:\Program Files\Exchsrvr\exchweb and all of its subfolders did not have the IUSR_ permissions set and therefore wouldnt allow people to get the images etc. hence the red crosses.

Thanks for all your help anyway.

Hi I'm sorry I can't help with this as I have slept since 3.5 years ago! I'm not sure which server it was in order to check it out either, there must be more info on here I would have thought. The most common issue I have come acrtoss is that the IIS folders do get the permissions mixed up and need resetting, Sorry for being unhelpful.
