ADAM port is already in use
Topic Last Modified: 2006-06-06
Microsoft® Exchange Server 2007 setup cannot continue because its attempt to install the Gateway Server role detected that the ports assigned for Active Directory® Application Mode (ADAM) synchronization are already being used.
ADAM is a Lightweight Directory Access Protocol (LDAP) directory service that is designed specifically for use with directory-enabled applications. ADAM stores and replicates only application-specific information and does not require deployment on a domain controller or depend on the Active Directory service. ADAM does not provide network operating system authentication or authorization.
In Exchange 2007, the gateway server uses ADAM to store configuration information. When ADAM is synchronized with Active Directory directory service, it can also be used to perform recipient lookup for message security.
Microsoft Exchange setup requires that specific ports be available (unused) so that they can be assigned to the ADAM synchronization process when the Gateway Server role is installed.
To resolve this issue, identify and stop the process that is already using the ports required for ADAM or run Exchange 2007 setup with command line switches to override the default ADAM port assignments.To run setup with an override of the default ADAM port assignments
At a command prompt, type the following:
Setup.exe /adamport:xxxx /adamsslport:yyyy
/adamport:<port number to assign to ADAM>
/adamsslport:<port number to assign to ADAM>
