How to Move Exchange Database and Logs

To move log files

  1. Start Exchange System Manager.
  2. Click Administrative Groups.

    Note If Administrative Groups does not appear, it may not be turned on. To turn on Administrative Groups, right-click Exchange Organization in Exchange System Manager, and then click Properties. Click to select the Display Administrative Groups check box.
  3. Locate the storage group where you want to change log file paths, right-click the storage group, and then click Properties.
  4. Click the General tab, click the Browse button next to the Transaction log location box, and then specify the new drive or folder location for the log files.

To move databases

  1. Start Exchange System Manager.
  2. Open the administrative group that contains the database that you want to change.
  3. Under Storage Group, right-click the mailbox store or the public folder store that you want to change, and then click Properties.
  4. Click the Database tab.
  5. Next to the database that you want to change, click Browse, and then specify a new drive or folder location for the files.

    Notes
    • With the databases, you can decide to move the Exchange Database (.edb file), the Exchange Streaming Database (.stm file), or both.
    • If the databases are still mounted, you receive the following message:
      You are about to perform the following operation(s):
      - change Exchange database location
      To perform the requested operation(s), the store must be temporarily dismounted which will make it inaccessible to any user.

      Do you want to continue?
      Click Yes to dismount the database automatically and move the location.
  6. When you finish moving the databases, remount the databases manually.
You can move the log files and database files to any folder that you want to create. When you move logs and database files, you may want to create the Exchsrvr\Mdbdata file structure for consistency reasons, but you are not obligated to do so.

You must grant the following default permissions to the new Mdbdata folder that contains the log files and database files:
  • Administrators: Full Control
  • Authenticated Users: Read and Execute, List Folder Contents, Read
  • Creator Owner: None
  • Server Operators: Modify, Read and Execute, List Folder Contents, Read, Write
  • System: Full Control
Note Only assign permissions to the Server Operators group if the Exchange server is a domain controller. Otherwise, assign permissions to the Power Users group. Only domain controllers should have permissions to the built-in Server Operators group. Stand-alone and member servers should have permissions to the built-in Power Users group.

You may also have to grant the following permissions to the root drive that contains the new Mdbdata folder:
  • System: Full Control
During the process of moving log files and database files, your store is temporarily dismounted. Because the store is temporarily dismounted, it is inaccessible to your users until the process is completed. Moving log files or database files invalidates all existing incremental and differential backups; therefore, make a full backup after these changes.

Do not delete or rename the Old MDBdata Folder path after you move the Exchange database. If you want to delete the old MDBdata folder, make sure that the following working directory parameter in the registry points to the new location:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MSExchangeIS\ParametersSystem
Value name: Working Directory
Value type: REG_SZ
Value data: C:\Program Files\Exchsrvr\Mdbdata
For more information, click the following article number to view the article in the Microsoft Knowledge Base:
298415 (http://support.microsoft.com/kb/298415/ ) Messages that have attachments are not delivered as expected, and Event ID 12003 and 327 messages are logged in Exchange 2000 Server and in Exchange Server 2003


Do not move databases to the root of a drive. Instead, move databases at least one subfolder down from the root drive. For example, do not use C:\ as the path of the database or log files. Instead, you could use the C:\Subfolder path. In an organization that uses Exchange 2003 and Exchange 2007, the 2007 management tools will flag database or log files that are the root of a drive as an error.

Open DNS vs Conficker

The Best way to keep secure is to prevent the malware in the first place. OpenDNS.com

http://blog.opendns.com/2009/02/09/stats-are-back-and-conficker/

The second announcement is significant to all OpenDNS users as well as the entire Internet community. Today we’ve rolled out a way for you to see if Conficker is living on your network. The Conficker worm, also called Downadup and Kido, is massive. Some estimates of how many PCs are compromised are as high as 10 million. What’s interesting about this particular virus is that it uses the Domain Name System in a unique way: Conficker contains an algorithm that checks 250 new domains per day for instructions on what it should do. This puts us in a unique position to keep you safe since we’re in the unique position of providing insight and intelligence into your DNS service. We’ve teamed with Kaspersky Lab to identify those 250 daily domains, and stop resolving them. This means if you’re using OpenDNS, Conficker will do your network no damage. Yet another reason for your friends and colleagues to make the switch. While OpenDNS represents just a tiny drop in the sea of the Internet users today, we think this is a smart move forward.

To find out if Conficker has penetrated your network, simply log in to your account and select Stats on the left sidebar. From there choose Blocked Domains and filter “only domains blocked as malware.” This will generate a list of malware sites your network has attempted to connect with.

This is just the beginning, folks. We’ve got a year’s worth of new features we’re cranking hard on to make your network better performing and more secure. Stay tuned…
