DOCUMENT:Q161481 12-APR-1999 [exchange] TITLE :XADM: Purpose of Integrity Checker (Isinteg.exe) -PATCH Option PRODUCT :Microsoft Exchange PROD/VER:winnt:4.0,5.0,5.5 OPER/SYS: KEYWORDS:kbtool kbusage ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Exchange Server, versions 4.0, 5.0, 5.5 ------------------------------------------------------------------------------- SUMMARY ======= The Microsoft Exchange Information Store Integrity Checker (Isinteg.exe) is used with the -PATCH option to modify the base GUID (generated unique ID or globally unique identifier) used by an information store. This procedure is performed after an information store is restored to ensure that the GUIDs assigned to objects in the information store are unique. MORE INFORMATION ================ A GUID is a 64-bit hexadecimal string that uniquely identifies a particular object. In the information store, the public and private information stores have base GUIDs that are used to generate GUIDs for all other objects, including folders, messages, and attachments. After you restore an information store, the information store does not know which GUIDs have already been assigned. If you do not change the base GUID, the public and private information stores may generate GUIDs that are not unique.
