Error running ISINTEG on a Cluster Server

MORE INFORMATION

In some cases Isinteg -patch may fail after you restore a database that was forklifted from a stand-alone Exchange Server 5.5 computer to a clustered Exchange Server 5.5 computer.

This failure is known to occur if the _CLUSTER_NETWORK_NAME_ environment variable has an incorrect value. The most frequent reason the environment variable is rendered invalid is a typographical error.

The error may occur if you type the incorrect or incomplete variable name, such as _cluster_network_name, or if you type an incorrect or incomplete NetBIOS name of the cluster. After the variable is set, it cannot be changed.

If the environment variable is set incorrectly, you must completely restore the database because the cluster name in the information cannot be changed.

Microsoft recommends that you take steps to make sure that you type the correct NetBIOS name for the cluster. One way to do this is to use a batch file that is similar to the following:

ECHO Enter the NetBIOS name of the Exchange Virtual Server : %1 
ECHO Is %1 the correct NetBIOS name ? 
ECHO If yes, press any key; else use ctrl-c, ctrl-break or end the dos prompt session.
PAUSE
ECHO Are you certain %1 is the correct NetBIOS name for the cluster ? 
ECHO If yes, press any key; else use ctrl-c, ctrl-break or end the dos prompt session.
PAUSE
SET _CLUSTER_NETWORK_NAME_=%1 
ECHO The cluster NetBIOS name and environment variable
ECHO _CLUSTER_NETWORK_NAME_ have been set to = %1 
ECHO press any key to execute isinteg -patch 
ECHO this is the last step in preparing the information store to start
PAUSE 
ISINTEG -PATCH 
PAUSE
