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.
