I have a win2k domain and an exchange 2k server for that domain. There is a child domain. I have created a new instance of mailbox store on the exchange server for this domain. All the users from child domain can access the exchange services perfectly via OUTLOOK. RUS is also running just fine.
The problem happens once they try to access OWA. For all the users on the child domain, OWA does not authenticate. Now it could be either of these two issues:
1. IIS on the Forest domain is not giving enough permission for these users to access OWA (I have tried to add the users of child domain to the Builtin\users group of forest domain, but that didn't help)
2. The mailbox store is different (but if you look at the exchange instance in IIS, you can see all the mailboxes, including the one's in child domain, so it seems more like issue number one up)
So, if anyone of you can quickly give a solution for this, I will truly appreciate it.
