Flush Transaction Logs in Exchange

Flush Transaction Logs in Exchange:

Your Exchange Logs get deleted when your database backup completes. When your exchange server receives an email it dumps the email to the transaction logs. When the exchange server free's up it then plays these logs into the database. Sometimes Exchange may not have played all the log files into the database, so you cant simply "delete" them.

1. Dismount the all Exchange Mailbox Databases under the Storage Group you wish to clean up.

2. Use the ESEUTIL program to view if all the logs have been played into the Exchange Database.

eseutil /MH database.edb



If all the databases are in a Clean Shutdown or Consistent state, you may remove all the transaction logs. Older versions say "Consistent", New Versions of Exchange say "Clean Shutdown". In my screenshot I'm using Exchange 2010.

Note: If it is not in a "Clean Shutdown" or "Consistent" state, you can use eseutil to reply the log files into the database or remount the database and allow Exchange to replay them.
Caution: Do not delete log files if the state is not "Clean Shutdown" or "Consistent" as you will loose email!

3. Delete all log files including the chk file. The checkpoint file keeps track of which log files have been and have not been played into the database. Since there are no log files anymore, the checkpoint is not needed.

Caution: If your database is in the same directory as your log files be careful you dont accidently delete your edb database file as well!

4. Re-mount your exchange databases in your storage group. This will automatically create a new checkpoint file ready to go!

Removing saved credentials

Removing Saved Credentials (passwords) from Windows XP, Windows Vista, or Windows 7:

 

To removed cached credentials

1. Click Start and select Run
2. In the Open field type "rundll32.exe keymgr.dll, KRShowKeyMgr"
3. Once the Stored Usernames and Passwords interface opens you can select any of the entries and select Properties to view the existing information
4. To remove a saved password you can select one of the entries and select Remove. A confirmation screen will appear. Click on OK and the account will be removed
5. You can add additional saved passwords as well by clicking on the Add button and entering the appropriate information
6. Repeat the steps above as needed to add, remove or edit saved passwords
7. When you are done using the interface click the Close button
That's all there is to it. This is a great way to see if, while working on a machine, you've accidentally saved your credentials, as any username/password combinations in this list will survive a reboot, and still be available.
