OWA - Bad Request (Invalid Hostname) / Owaauth.dll
Posted on 2007-08-10
Hello All, I have the following problem with one of my exchange 2k3 SP2 front end servers.
This new FE, owa-ex01, server can talk to every single server except for one BE, prob-ex01, (of course the only one I really need it to connect to.) Set for SSL Cert (owa.domain.com) and Form Auth.
My main FE, webmail-ex01, server is running fine. It will connect to every single BE server, even the above "problem" one. Set for SSL Cert (webmail.domain.com) and Form Auth.
The new FE server has been added in to support our (uhhhgggg Entourage Mac clients) The FE server is local to them so that they do not need to traverse wan to find the main FE server.
When I try and access any account on this specific server, prob-ex01, FROM the new FE server, owa-ex01, I get the following errors:
IE - Address Bar: https://owa.domain.com/exchweb/bin/auth/owaauth.dll
Page Cannot be found HTTP 400 - Bad Request
Firefox or IE with friendly Errors off - Bad Request (Invalid Hostname)
I've tried going though and reseting directory permissions
Deleteing and having the 6 IIS directories recreated
Made sure the IUSR_ and IWAM_ accounts have proper passwords
All servers are running MS Server 2003 SP1 and Exchange 2003 Sp2.
