How to Check a MD5 or SHA1 Checksum on a File in Windows

Filed under: Technology — Tags: , — admin @ 10:15 am

Many shareware and open source projects are using MD5 or SHA1 checksum’s to ensure that the executable file you download is the authentic executable you are about to run on your computer.

A checksum will be a long ugly looking strong like this MD5 checksum: 5b8a3ce687052c70d3ec524945a70fc4a68f5b5b.

To check that the file you downloaded is authentic, you can use a command line tool from Microsoft called “FCIV”.

The tool and instructions on how to use it is available here: http://support.microsoft.com/kb/841290.

Using the Active Directory PowerShell Cmdlet’s

Starting in Windows 2008 R2, Microsoft included a PowerShell Active Directory module which includes a group of cmdlets to perform various administrative, configuration, and diagnostic tasks in your Active Directory environment. You can use these cmdlet’s to manage existing Active Directory user and computer accounts, groups, organizational units (OUs), domains and forests, domain controllers, and password policies, or you can create new ones.

The Active Directory module is available:

  • On Windows 2008 R2 server when you install the AD DS or AD LDS server roles.
  • As part of the Remote Server Administration Tools (RSAT) feature on a Windows Server 2008 R2 server
  • As part of the RSAT feature on a Windows 7 computer

To use the AD cmdlet’s you will need to import the ActiveDirectory module in PowerShell (V2 is required):

Import-Module ActiveDirectory

or

%windir%\system32\WindowsPowerShell\v1.0\powershell.exe -noexit -command import-module ActiveDirectory

A key requirement to use the AD cmdlet’s to manage an Active Directory deployment is the following:

A Windows Server 2008 R2 Active Directory Web Services (ADWS) service must be installed on at least one domain controller in the AD domain or on one server that hosts your AD LDS instance. For more information about ADWS, see AD DS: Active Directory Web Services (http://go.microsoft.com/fwlink/?LinkID=141393).

If you receive this error:

‘Unable to find a default server with Active Directory Web Service running’

You do not have ADWS installed on at least one DC.

In addition, to use the Active Directory module in PowerShell to access or manage Active Directory services that are running on Windows Server 2008 or Windows Server 2003 computers, you need to install the Active Directory Management Gateway Service. See the Active Directory Management Gateway Service (Active Directory Web Service for Windows Server 2003 and Windows Server 2008).

Here is a useful cmdlet (that doesn’t require the ActiveDirectory module) to get information about your AD environment:

[System.DirectoryServices.ActiveDirectory.Forest]::GetCurrentForest()

Filed under: Uncategorized — admin @ 9:20 am

An interesting tid-bit I always wondered about – how much water is wasted while we do things like leave the tap on while brushing our teeth?

Thames Water estimated that leaving the tap running while brushing our teeth is sending about 120 Billion Litres of water down the drain: http://www.thameswater.co.uk/cps/rde/xchg/corp/hs.xsl/14234.htm.

iPhone/iPad Setting to Automatically Download New Purchases to Other Devices

If you have multiple Apple devices you might be interested in automatically having any new purchases on one device (say your iPhone) automatically download and install on your other device (say your iPad).

You can control whether Apps or Books are automatically synchronized.

The setting is somewhat hidden the Store Settings.  Go to Settings > Store and you will see the setting there.

iTunes – The Library Files and Adding to the Library

The iTunes “Library” is really and index into all your media and applications; not really a library of content per se.

It consists of two files:

  1. iTunes Library.itl
  2. iTunes Library.xml

On Windows 7, the “Library” (these 2 files) are located in the path “\Users\<username>\My Music\iTunes\“.

For more information see this link: iTunes: What are the iTunes library files?

To add media to your iTunes Library that resides in a folder other than the default iTunes library folder, Import them in iTunes. That adds those files to the Library index, but keeps the actual media (e.g. mp4 file) in the original folder.

On the Windows version of iTunes use the “Add File to Library” or “Add Folder to Library” functionality.

For more information see this link: iTunes: About the Add to Library, Import, and Convert functions

This will add those files or folders to the iTunes index (Library) so that you can access them from iTunes and synchronize the content with other devices.

10 Tips to help you Clean Out Your Inbox

A really good article on improving the productivity of your email experience: http://www.inboxdetox.com/blog/10-tips-to-help-you-clean-out-your-inbox.

10 Tips to help you Clean Out Your Inbox

This post was written by Marsha Egan
Posted Under: Email Best Practices,Email Productivity Tips and Solutions,Productivity,Tips

To inaugurate “Clean Out Your Inbox Week” January 28 – February 1, we offer these 10 tips to help you get to “zero” by the end of this week!
1. Create e-folders to hold action items – avoid using your inbox as a “to do” list
2. Rename received e-mails so that you can search them more effectively
3. Return e-mail requests with phone calls
4. Avoid the tendency to “work” newly received e-mails if they are less important than your current project
5. Open your e-mail with the intention of sorting your new items, rather than “knocking the easy ones off”
6. Sort your e-mail in order from top to bottom or bottom to top – avoid scrolling
7. Copy only the people who REALLY need to see your message
8. Use “if/then” verbiage. e.g. “Please e-mail me if you haven’t received the package” rather than “Did you receive the pkg?”
9. Turn off automatic send/receive and turn off all dings and flashes. Open your e-mail when it is right for YOU
10. Send less e-mail. The more e-mail you send, the more e-mail you’ll get!
