Enterprise Vault tasks use MSMQ to communicate with the Storage service. If you want to install Enterprise Vault services on more than one computer in the network, you must configure MSMQ on each computer.
The steps for installing MSMQ on Windows 2003 and 2008 are different. Follow the instructions below for your operating system.
Note that Active Directory Integration should not be enabled when installing MSMQ.
To install MSMQ on Windows Server 2003
In the Windows Control Panel, double-click Add/Remove Programs.
Click Add/Remove Windows Components. The Windows Components wizard starts.
Select Application Server and then click Details to open the Application Server window.
Check Message Queuing, and then click Details to display the Message Queuing dialog box.
As installing MSMQ with Active Directory Integration affects the performance of Enterprise Vault, you are strongly recommended to uncheck Active Directory Integration in the Message Queuing dialog box.
