IMPORTANT: This article contains information about editing the registry. Before you edit the registry, make sure you understand how to restore it if a problem occurs. For information about how to do this, view the "Restoring the Registry" Help topic in Regedit.exe or the "Restoring a Registry Key" Help topic in Regedt32.exe.



SYMPTOMS
When restoring a private information store server with no public information store present, using ARCserve 6.x, you may encounter an error 3355445011 when starting the store.



CAUSE
The Cheyenne ARCserve backup program places entries in the Windows NT Server's registry, which forces the information store to search for files that were not restored from tape. Because the public information store files were not restored, entries for the Pub.edb should not exist in the registry. If private and public files exist, when only the private or the public store has been restored, the information store will search for both stores during startup, and produce an error.



WORKAROUND
WARNING: Using Registry Editor incorrectly can cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk.

For information about how to edit the registry, view the "Changing Keys And Values" Help topic in Registry Editor (Regedit.exe) or the "Add and Delete Information in the Registry" and "Edit Registry Data" Help topics in Regedt32.exe. Note that you should back up the registry before you edit it. If you are running Windows NT, you should also update your Emergency Repair Disk (ERD).

 Restore the private information store using ARCserve. After the restore completes, DO NOT START THE SERVICES.  Start Registry Editor (Regedt32.exe). Locate the following key in the registry:   HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\ MSExchangeIS\Restore in Progress NOTE: The above registry key is one path; it has been wrapped for readability.   Modify the following value in the registry.      Value Name: EDB_RstMap Data Type: REG_MULTI_SZ Value:   \\SERVER1\e$\exchsrvr\MDBDATA\PRIV.EDB \\SERVER1\e$\exchsrvr\MDBDATA\PRIV.EDB \\SERVER1\e$\exchsrvr\MDBDATA\PUB.EDB \\SERVER1\e$\exchsrvr\MDBDATA\PUB.EDB   Remove the two lines that have references to the PUB.EDB. This should leave two lines in the value field as below. <pre class="fixed_text">        Value Name: EDB_RstMap Data Type: REG_MULTI_SZ Value:   \\SERVER1\e$\exchsrvr\MDBDATA\PRIV.EDB \\SERVER1\e$\exchsrvr\MDBDATA\PRIV.EDB NOTE: The values in the value field above will differ in your environment and should not be changed. </li> Click OK.</li></ol> </li>  Modify the following value in the registry. <pre class="fixed_text">     Value Name: EDB_RstMap Size Data Type: DWORD Value: 00000002 Change the value to 00000001 </li> Exit the registry editor.</li> Start the Exchange Server information store.</li></ol>
