OWA and cross domain authentication

[UnibankBS]

Here is the situation.....

I have two domains

Bank.domain.com
and
sterling.domain.com

BOTH domains share one exchange 2003 server (all malboxes reside in one exchange server) The exchange server lives in the BANK.domain.com.


Users in the STERLING.domain.com want to login to OWA.... they come to the login page.... when they login I normally tell users to login as follows:

username: STERLING\USERNAME_HERE
pw: that persona's password.....



When they hit return, it does not allow authetication to go forward..... Note: This was working for like the past 6 months and now NO AUTHENTICATION is allowed. I will say this... an ISA server was put in about 2-3 months ago.... I'm using the box as a caching server only (which filters ONLY HTTP and HTTPS traffic)

Id there something I need to modify in IIS on the exchange server? Should I try adding a permit rule to allow anyone on b0oth domains to access the OWA box?

(note: authentication will not work internally via OWN or externally)

Can you paste a part of your logfile from IIS, that are located in C:\WINDOWS\system32\LogFiles, probably W3SVC1...

Need to isolate if the problem is with the ISA or Exchange permissions.

If you are on a box on Bank, do you get in when logging in as someone from stirling?

Also, check Exchange server logs.
