XCON: MTA Associations Fail On MSCS Installation (186756)
The information in this article applies to:
- Microsoft Exchange Server 5.5
This article was previously published under Q186756 SYMPTOMS
When you use Microsoft Exchange Server as a messaging bridgehead on a
Microsoft Cluster Server (MSCS) installation, the MTA may fail to read the
virtual IP address correctly. This causes the incorrect IP address to be
utilized for attempted connections, and MTA associations fail.
CAUSE
In this scenario, the clustered configuration consists of two nodes that
share one or more common physical disk drives, an IP address, a network
name, and the Microsoft Exchange Server cluster resource. All network
requests to the clustered Microsoft Exchange Server computer are directed
at the virtual server defined by the cluster, not at an individual node.
It is the active node that receives and processes these requests on behalf
of the cluster. The MTA fails to properly initialize a variable for
the cluster API, which prevents correct usage of the virtual IP address
assigned to the clustered resources.
STATUS
Microsoft has confirmed this to be a problem in Microsoft Exchange Server
version 5.5. This problem has been corrected in the latest U.S. service
pack for Microsoft Exchange Server version 5.5. For information on
obtaining the service pack, query on the following word in the Microsoft
