Hi
I have FE/BE server...
both windows 2003 sever SP1 and Exchange 2003 SP1

FE:
Srv2  192.168.0.2

BE:
Srv1  192.168.0.1
CA, DNS on Srv1:
mail A 192.168.0.2
mail MX 192.168.0.2
srv2 A 192.168.0.2
srv1 A 192.168.0.1
NS: srv1.domain.com

Exchange mail server url for internal and external:
https://mail.domain.com/exchange

My problem:
it got past the 440 timeout error by:
(Resetting IUSR_<servername> and  IWAM_<servername> account on Domain
Controller and
editing IIS-->ExchWeb-->Enable Anonymous Access--> Domain/ IUSR_<servername>
on FE
server)

now: I get the login screen but no login account works!
I Tried resetting the accounts and or creating a new user, no login will
work.
I also tried the admin login no luck.
Sound like a authentication error again:
The page must be viewed over a secure channel
The page you are trying to access is secured with Secure Sockets Layer
(SSL).
Type https:// at the beginning of the address you are attempting to reach
and press ENTER.
HTTP Error 403.4 - Forbidden: SSL is required to view this resource.
Internet Information Services (IIS)

I did also at IIS: (on Exadmin, Exchange):
in "Authentication and access control" enable:
Basic Authentication (password sis sent in clear text)
and also in Secure communication enable:
Require secure channel (SSL)
Require 128-bit encryption
I get the login screen but no login account works!

I can login to:
https://srv1.domain.com/exchange
and
https://srv1/exchange
with no problem! (but not forms-based)

but I can't login to:
https://srv2.domain.com/exchange
and
https://srv2/exchange
and
https://srv1.domain.com/exchange
and
https://mail.domain.com/exchange

please help...... how I can solve this problem?
Thanks
