SYMPTOMS
When you install Microsoft Exchange 2000 Server or Microsoft Exchange Server 2003 on a Microsoft Windows 2000-based cluster, there is only one Message Transfer Agent (MTA) resource per cluster.



CAUSE
This behavior is by design. The MTA resource is not cluster-aware. There is one MTA resource per cluster.



MORE INFORMATION
The MTA is an Active/Passive cluster resource. There can only be one MTA per cluster. On Active/Active clusters, only one virtual Exchange server will have the MTA resource. The MTA is created on the first Exchange virtual server and serves all Exchange virtual servers in the cluster.
