http 400 Bad Request (Invalid Hostname)

Our exchange Outlook Web Access server started giving us the following error this morning:

http 400 Bad Request (Invalid Hostname)

I have followed all the documents I could find on experts-exchange and nothing seems to work.  

owa/exchange = same error
ipofowa/exchange = same error

We have disabled SSL on our server and it still doesn't work.  

We currently have a backend cluster with a front end-OWA and a bridgehead server.

We fixed it by using this Article:  http://www.winserverkb.com/Uwe/Forum.aspx/exchange-admin/19854/Front-End-problem-Bad-Request-Invalid-Hostname

The Backend cluster had a hostheader.  Removed it and everything works great.
