ID: Q154032
|
The information in this article applies to:
-
Microsoft Exchange Server, version 4.0
SUMMARY
When you restore an offline store from a Microsoft Exchange Server 4.0
computer, with or without Microsoft Exchange Server Service Pack 1 (SP1)
installed, onto a Microsoft Exchange Server 4.0 computer with Microsoft
Exchange Service Pack 2 (SP2) installed, you will receive the following
error:
1087 The information store was restored from an offline backup. Run
ISINTEG -patch before starting the information store.
1005 Unable to start the Microsoft Exchange Information store. Error
1011
When you run ISINTEG -patch, you will receive an EcBadVersion error.
If the store was recovered from an online backup, the following events
will be logged:
Unable to recover the database because error 0x00000451 occurred
after a restore operation.
Unable to initialize the Microsoft Exchange Information Store
service. Error 1105.
MORE INFORMATION
This is because a new version of Mdbrest.dll was provided with SP2. To
workaround this problem, follow these steps:
- Rename Mdbrest.dll in the Exchsrvr\bin directory to Mdbrest.new.
- Copy Mdbrest.dll from a Microsoft Exchange Server version 4.0 with or
without SP1 (there was no change to this file in SP1) to the
Exchsrvr\bin directory.
- If the store was recovered from an off-line backup you must run
ISINTEG -PATCH. This will update the store.
- Delete Mdbrest.dll and rename Mdbrest.new to Mdbrest.dll.
- Start the Microsoft Exchange Information Store.
