Disable hyper-threading on a Poweredge R720xd

I was asked to disable hyper-threading on one of our Dell PowerEdge R720XD servers. Looking in the BIOS it doesn’t stand out as an option however it does exist. You simply need to select the logical processor setting and set its value to disable and this will in turn disable hyper-threading, because it will only report one logical process per core.

I hope this helped some of you

Identify Microsoft SQL Server version & edition

I wanted to determine which version of Microsoft SQL Server 2008 was running on one of my servers. So I opened up SQL Server Management Studio (SSMS), and ran the following command as a new query window:

SELECT SERVERPROPERTY (‘productversion’),
SERVERPROPERTY (‘productlevel’),
SERVERPROPERTY (‘edition’)

The following results are returned:
-The product version (for example, 10.0.1600.22)
-The product level (for example, RTM)
-The edition (for example, Standard Edition 64-bit)

sending sms, mms, txt messages to phones with email

Most, if not all mobile carries have “SMS Gateways” that an take in an email messages and deliver them to their customer as text messages. This works also with mms messages.

That seems simple doesn’t it!  It is, if you know the carrier the recipient’s phone is on, along with their phone number.  Below are a few I have found:

AT&T Wireless (Formerly Cingular): number@mms.att.net
AT&T Wireless (Formerly Cingular): number@txt.att.net

Sprint (PCS): number@messaging.sprintpcs.com
Sprint (Nextel): number@page.nextel.com

Verizon: number@vtext.com
Verizon: number@vzwpix.com

I’ve found a larger List of SMS Gateways.  This may be more up to date and consisting of a larger number of phone carriers.

Problem Steps Recorder

A quick pffffft:

The Problem Step Recorder (PSR) is a little known feature of Windows 7 which allows you to record your desktop along with applications and activities so you can later show someone such as a tech support person or even give a demo on how to use something in Windows.  This is very handy if you are remote from the user or supporting them during hours where neither of you are able to work together in real time.

Thumbs up to Microsoft for adding this feature!

How-to use:

Click Start and type PSR and press Enter.  A window will open with some basic control features such as ‘record’. Now setup your environment so that you are ready to reproduce your steps and click Start Record.  When completed you stop the recording.  Problem Steps Recorder will record every click and key press, take screen grabs, and package everything up into a single zipped MHTML file.

As you can see, no need for third party apps, because you have what you need.

I hope this helps you one day or helps you help someone else.
