Hello,

 

I have published Exchange 2007 OWA with my ISA 2006 Server. Each time I
connect I have to authenticate twice?

 

The ISA web listener is configured to use HTML Form Authentication with
Windows Active Directory.

 

The application Settings in the publishing rule uses the customized HTML form
for exchange.

 

Authentication delegation is Basic.

 

Any ideas why the auth is happening twice?  The second one allows access.

 

I am sure I just missed something. Can anyone help me out?

 

Thanks

 

Bill
