The information in this article applies to:

- Microsoft Exchange Server, versions 4.0, 5.0, 5.5

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).

1. Restore the private information store using ARCserve.

2. After the restore completes, DO NOT START THE SERVICES.

3. 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.

4. 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


  a. Remove the two lines that have references to the PUB.EDB. This should
     leave two lines in the value field as below.

        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.

  b. Click OK.

5. Modify the following value in the registry.

     Value Name: EDB_RstMap Size
     Data Type: DWORD
     Value: 00000002


  Change the value to 00000001

6. Exit the registry editor.

7. Start the Exchange Server information store.
