I recently installed a Microsoft Exchange 2003 SP 2 front end server, this server is located behind my firewall. I also have an Exchange 2003 (No service pack) Back End server. I am trying to set up Outlook Web Mail. I am able to log into the back end server using Http://servername/exchange/mailbox
. I get a login box and I enter the Domain/Username and the password and I am able to use the Outlook Web page. When I try to log into the front end server using the Http://servername/exchange/mailbox.I
get the login box and enter the Domain/user name and the password. I try three times and get access denied. It is like I am not able to authenticate. I have completely rebuilt the server a few times. Both servers are running Windows 2003 SP1.
Do both exchange server need to be on the same service pack?
