SYMPTOMS
After you run the Microsoft Exchange Information Store Integrity Checker (Isinteg.exe) with the -PATCH option on an Exchange Server computer on which Microsoft Cluster Server is installed, you may be unable to start the information store. When you attempt to do so, you may receive an error message indicating that the information store and directory databases are inconsistent and that you need to run the ISINTEG -PATCH command again.

Note that this problem occurs even when you properly set the _CLUSTER_NETWORK_NAME_ environment variable before you run Isinteg.exe with the -PATCH option.



CAUSE
When you run Isinteg.exe with the -PATCH option, it modifies the base GUID (generated unique ID or globally unique identifier) used by the information store, but it does not notify Microsoft Cluster Server that the change has taken place. This causes Microsoft Cluster Server to overwrite the new base GUID, because it thinks the GUID is invalid.



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 Knowledge Base (without the spaces):

MORE INFORMATION
For additional information about setting the _CLUSTER_NETWORK_NAME_ environment variable before you run Isinteg.exe with the -PATCH option, please see the following article in the Microsoft Knowledge Base:
