Solution 2: Reinstall the Feature Pack; then perform a configuration update to recreate the
DFS links.
Notice
Before you uninstall the Feature Pack, it is important to verify that all remotely stored Exchange
databases were shut down cleanly. If you reinstall the Feature Pack while corrupted databases are
stored on Windows Storage Server computers, recovery procedures in Exchange might not work
correctly for those databases.
1.
Dismount all Exchange databases stored on the Windows Storage Server computer.
2.
Verify that all databases shut down cleanly. To verify the state of each database, perform the
following steps:
a. On the Exchange server, navigate to the %ProgramFiles%\Exchsrvr\bin folder.
b. At a command prompt, type the following to view the first 4 kilobytes (KB) of the
database file:
eseutil /mh
filename.edb
c.
In the State field, verify the state of the database: Clean Shutdown or Dirty Shutdown.
If the Exchange databases did not shut down cleanly, you will need to fix the problems with
the databases. For information about troubleshooting problems with Exchange databases,
see Knowledge Base article 328763, “Troubleshooting a Corrupted Exchange Database”
(
http://go.microsoft.com/fwlink/?LinkId=23122
).
3.
If all remotely stored databases were shut down cleanly, dismount all stores on the Exchange
server. For a clustered Exchange server, dismount all databases on the virtual server.
This ensures that the reinstallation does not corrupt any remotely stored database that is
functioning and online during the process.
4.
Reinstall the Feature Pack by using the procedures that are described in Chapter 2, “Installing
the Feature Pack.”
You must uninstall the Feature Pack before reinstalling the same Feature Pack version.
Reinstalling the Feature Pack creates the DFS root and local drive mapping that Exchange
uses.
5.
To recreate the DFS links to Exchange shares on the Windows Storage Server computer,
perform a configuration update for each storage group that the server hosts. You must do
this for all databases, not just the ones that were corrupted.
For instructions for moving Exchange files to a Windows Storage Server computer, see
Chapter 3, “Moving Exchange Files to a NAS System”
6.
Mount the stores in Exchange.
7.
After you remount each store, back up the Exchange database immediately.
The mapped drive that Exchange uses was deleted or is not being created.
If the mapped drive that Exchange uses was deleted or is not being created, another application
or process might be using the designated drive. If the designated drive is already in use, you can
resolve the problem by changing the drive letter that Exchange uses. However, before you
change the local drive letter that Exchange uses, try to solve the problem by restarting the
Windows Storage Server Mapping Service.
