- (.mdf) extension which contains the data.
- (.ldf) extension which contains log.
Log file size increases very rapidly and depend on the operation performed on the data. After a long time period this file becomes too large. When log file is too large it takes time to perform some operations like ( attach , de-attach, backup, restore … etc ).
This article explains how to configure your Windows Server 2008 R2 Active Directory Primary Domain Controller to syncronise time with an external time source.
Note: In an active directory, all member computers will sync time with the PDC, so you only need to setup an external time source on the PDC.
Open an elevated command prompt and type the following:
Note: this is for switzerland. More NTP names can be found here: http://www.pool.ntp.org/en/
w32tm /config /manualpeerlist:"0.ch.pool.ntp.org 1.ch.pool.ntp.org 2.ch.pool.ntp.org 3.ch.pool.ntp.org" /syncfromflags:manual /reliable:yes /update
net stop w32time
net start w32time
w32tm /config /update
You can run W32tm /resync on member computers to sync time with the PDC.

How can I find all computer accounts in my Active Directory domain that have been inactive for x days using PowerShell?
This would give you all computer accounts that have no activity for the last 365 Days.
Search-ADAccount -AccountInactive -ComputersOnly -TimeSpan 365.00:00:00
This would sort it for you by lastlogondate.
Search-ADAccount -AccountInactive -ComputersOnly -TimeSpan 365.00:00:00 | Sort-Object lastlogondate | Ft name,lastlogondate -auto
This would give you disabled computer accounts.
Search-ADAccount -AccountDisabled -ComputersOnly
On a recently setup Windows Server 2008 R2 terminal server, Java was installed, and by default the JRE will enable automatic updates for all users. No daily users have administrative privileges, but all users are prompted to install updates. No users can actually install the available updates, nor can they disable the update check via the Control Panel.
I’m streaming a lot of my media directly to my Samsung TV (Allshare). lately I added music to my Music Library in Microsoft Windows 8. The Library is shared using DLNA Protocol. For some reason, the newly added media did not show up am my Samsung TV. I started playing around with the configuration of DLNA/Homegroup/Sharing and finally I realized (and that’s an assumption), that the whole sharing stuff, especially when it comes to indexing the media, is managed by Windows Media Player (WMP).
I started Windows Media Player and under Streaming I clicked on More Streaming Options
Combobox Show Devices On => choose All networks
Select the relevant Device and click on Customize.
Then uncheck “Use Default settings”
and then check “Make all my media available to this device.”
Finally my newly added media has shown up in Allshare/Samsung TV.
