Over the last 2 months OWA has stopped working on IE browsers. It started with one workstation and then spread to others. What I mean is that for example, Workstation 1,2,3,4,5... can use OWA while workstation 6 can not. But workstation 6 can when using a browser other then IE. A few day later workstations 2 and 3 stop working and eventually all IE clients stop. This is happening both inside and outside the firewall. I am the only person who makes changes to the OWA environment and over the past 6 months I've only applied windows updates.

Hi Erick Could please Be more specfic in regards to the error Message that you get when trying to browse OWA in IE or any event id you get in event veiwer or can also refer http://support.microsoft.com/kb/326303

I have a similar problem. Two machines running an older version of IE6 can access OWA. All the other ones with updated versions report script errors when trying to open new windows.
