CAUSE ===== Starting in Windows NT 4.0 SP4, there are changes in the heap manager that may prevent the information store from allocating memory that it had previously freed. RESOLUTION ========== WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk. 1. Start Registry Editor (Regedt32.exe), and locate the following registry key: HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\Image File Execution Options 2. Click the Image File Execution Options key, and then click Add Key from the Edit menu to create a new key with the name "store.exe" (without the quotation marks). You can leave the Class field blank. This Key Name entry should not include a path, only the name of the executable itself. 3. Click the new key you created in step 2, and then click Add Value from the Edit menu to create the Value Name: DisableHeapLookaside and Data Type: REG_SZ. 4. Click OK, and then type "1" (without the quotation marks) in the String field. Summary for the above entries: Key Name: store.exe Class: Value Name: DisableHeapLookaside Data Type: REG_SZ String: 1 5. You do not usually need to restart the system to see the results. You can usually simply restart the Exchange Server information store because this registry value is inspected during each process initialization. However, you may need to restart the computer to properly restart the information store.
