How the Account Setup Assistant works 
When the Entourage 2008 Account Setup Assistant is used to set up a Microsoft Exchange Server 
mail account, the Account Setup Assistant performs the following steps to locate the information it 
needs from the computer that is running Exchange server in the following sequence. 
1.  The Account Setup Assistant queries the DNS server for all DNS resource records for its 
domain name. It is looking for the global catalog server (LDAP server) for the Active 
Directory domain to which the user account belongs. To perform this query, the 
Account Setup Assistant uses a DNS server that is configured in Mac OS X under 
Network Preferences
 on the 
TCP/IP
 tab. If no DNS server has been configured, the 
Account Setup Assistant uses a DNS server that is assigned by DHCP. This query returns 
all of the resource records for the Active Directory domain controllers that are hosted 
by the DNS server. The Account Setup Assistant then uses the priority rankings that are 
returned by the DNS server to select the catalog server that it will use. After the global 
catalog server is found, the Account Setup Assistant authenticates to that server and 
then performs an LDAP query for the 
homeMDB
 attribute of the user account. This 
attribute provides the host name for the Exchange server that stores the user's mailbox. 
In addition, the global catalog server is set as the Directory Service server for the 
account. 
2.  If the query to the DNS server is not successful, the Account Setup Assistant tries to 
locate the Exchange server by using the name of the domain that the user entered for 
his or her Microsoft Exchange account. For example, if mydomain.microsoft.com was 
entered as the domain for a Microsoft Exchange account, the Account Setup Assistant 
creates a DNS query for the name mydomain.microsoft.com. The DNS resource records 
that are returned in response to this query include the records for the domain 
controllers in the domain, which then can be queried for the Exchange server 
information.  
3.  If the Account Setup Assistant cannot find information about the Exchange server, it 
provides the option to manually enter the information. The required information might 
include the name or address of the Exchange server and the name or address of the 
public folder server, which also provides the free/busy data. 
Note 
If Entourage cannot find the 
homeMDB
 attribute, this is usually because Entourage could 
not find the user object in Active Directory. In this situation, you might find it useful to use the 
LDP.exe tool to connect from a Windows-based computer to the LDAP service that is returned 
by the DNS query. The LDP.exe tool is included in the Support Tools for Windows 2000 Server 
and Windows Server 2003. Also, make sure that the user's Active Directory object is replicating 
properly to the target domain controller and that the 
homeMDB
 attribute is being returned 
correctly.
