Receiving Error – ‘ The security database on the server does not have a computer account for this workstation trust relationship ‘

Filed Under (Dorky Stuff, Tech Stuff) by admin on 22-05-2013

I ran across this issue after having to replace a Windows 2008 R2 System.  I wanted to keep the server name of the new system the same as the old –  (SERVER1) because I wanted to prevent end users from having to delete and re-add any of their network printer resources.  Additionally, many antivirus software clients running on desktops/laptops communicated with this specific server name for their virus definition updates.
I renamed the old server “SERVER1″ –TO–> “SERVER5″  and brought the brand new system online as “SERVER1″ and joined it into the DOMAIN without issue.  I needed the old server to remain online in the event of a problem.  The system actually ran perfectly fine but a week later I began receiving the trust relationship error shown below when I would try and login to the console with the administrator account.  On one of the network domain controllers I saw the System Event 11 generated as shown below:

Windows 2008R2 Error When Attempting to Login With Administrator Account

According to Microsoft – http://support.microsoft.com/kb/321044/en-us

This problem occurs because two or more computer accounts have the same service principal name (SPN) registered. Event ID 11 is logged when the Key Distribution Center (KDC) receives a ticket request, and the related SPN exists more than one time when it is checked on the global catalog (GC) for forestwide verification.  My simple explanation is that the original process of switching SERVER1 to a new temporary name didn’t go right.

The fix was pretty painless.  On the problem server open up a command line and type the following replacing SERVERNAME with the problem system (In this example SERVER1)
note-the first character is an l and not the number 1

ldifde -f c:check_SPN.txt -t 3268 -d “” -l servicePrincipalName –r “(servicePrincipalName=HOST/ServerName*)” -p subtree

Now find the file check_SPN.txt on your drive

The contents of the check_SPN.txt file that is generated should show something similar to the following.  Using the following output information SERVER1 is the system we are having trouble with.  SERVER2 is no longer in service.  As you can see the second portion of the output has a mix of both SERVER1 and SERVER 2 in its output

dn: CN=SERVER1,OU=Servers,DC=YOURDOMAIN,DC=com
changetype: add
servicePrincipalName: WSMAN/SERVER1
servicePrincipalName: WSMAN/SERVER1.YOURDOMAIN.com
servicePrincipalName: TERMSRV/SERVER1
servicePrincipalName: TERMSRV/SERVER1.YOURDOMAIN.com
servicePrincipalName: RestrictedKrbHost/SERVER1
servicePrincipalName: HOST/SERVER1
servicePrincipalName: RestrictedKrbHost/SERVER1.YOURDOMAIN.com
servicePrincipalName: HOST/SERVER1.YOURDOMAIN.com

dn: CN=SERVER2,OU=Servers,DC=YOURDOMAIN,DC=com
changetype: add
servicePrincipalName: HOST/SERVER2
servicePrincipalName: RestrictedKrbHost/SERVER2
servicePrincipalName: TERMSRV/SERVER2
servicePrincipalName: WSMAN/SERVER2
servicePrincipalName: WSMAN/SERVER1.Mcbassoc.com
servicePrincipalName: TERMSRV/SERVER1.Mcbassoc.com
servicePrincipalName: RestrictedKrbHost/SERVER1.Mcbassoc.com
servicePrincipalName: HOST/SERVER1.Mcbassoc.com

Hop into your domain controller and open “Active Directory Users and Computers” and right-click on your domain.  Click “Find” and change the drop down option to “Computers”.  Type the server name that is the equivilent to SERVER2 in the above example and DELETE it.  You should now be able to login to SERVER1 and carry on with your day!

 

Congratulations NASA on Getting Curiosity to Mars

The clock ticked from midnight all the way through to 1:32am Monday morning as I sat glued to my laptop watching a live stream from the Griffith Observatory in California where a packed crowd gathered to watch the suspensful conclusion to the long journey of the Curiosity Mars Science Laboratory (MSL) Rover.  I would have loved to be in the control center as the NASA Jet Propulsion Laboratory and world witnessed a part of history.  I love space and always have ever since I was a kid.  I am an engineer at heart and can appreciate the complicated series of events that had to take place in order for this to work out the way it did.  I have since watched all of the press conferences and I like how everybody is open to explaining where things stand.  This is all uncharted territory and nobody can fully predict what’s to come. I wish I knew somebody so I could get an inside look at the operations. :)  

I’m now ready for even more exciting things to come and seeing  the highly anticipated high definition images / videos when they finally beam their way back here to Earth.  Curiosity is bound to turn into amazement.

My Name Landed in a Delco Times Article

My name landed in the paper for the first time in a while since I was a kid throwing snowballs at my brother. A story relating to a major widespread outage of Comcast TV/Internet services throughout Delaware County had contributions by me.  I was contacted by a reporter regarding the outage and how it impacted the services of the email/web related services with regards to Vazoom (www.vazoom.com)
Comcast you still rock!

Venus and Jupiter Appearing Near One Another

Filed Under (Dorky Stuff, Just Interesting) by admin on 15-03-2012

Gazing into the night sky reminds me of the neat space illustration books I had when I was a kid. I believe one of my first ideas on what I wanted to be when I got older was an astronaut.  I loved my toy space shuttles.  Last night I peeked up into the sky for the second night in a row and viewed Jupiter and Venus.

 

There is a great program called Google Sky Map that you can download to your smart phone which acts as your binoculars into spectacular views of stars and planets surrounding our world. Simply install the program and point your device up as if it were your eyes and you will be amazed at how accurate it is.

 

Jupiter and Venus appear to be in close proximity to one another once every 24 years according to Space.com. The last time they appeared this close in view to use was in 1988. The graphic below from Solar System Live gives an idea of how we are view the two planets from our standpoint.

Using the Google Sky Map program while pointed toward Venus and Jupiter with my phone, I snapped a screen shot image from my Android. Pretty neat!

I also snapped a very low quality pic from March 14, 2012 looking up at the two planets.

Vazoom Closer to Becoming a Registered Trademark

Filed Under (Dorky Stuff, News, Various) by admin on 25-01-2011

With the official release of the January 25, 2011 U.S. Patent Office Gazette the request for trademark of Vazoom goes up for opposition. It’s been interesting to see the process by which new trademarks are filed for and granted.  It’s also quite a shock to see how many trademarks are applied for and modified.  The entire process is for the most part public knowledge too.

Any party who believes it will be damaged by the registration of the mark may file a notice of opposition (or extension of time therefor) with the Trademark Trial and Appeal Board.  If no party files an opposition or extension request within thirty (30) days after the publication date, then within twelve (12) weeks of the publication date a certificate of registration should issue.  Below is the official mark and description.  A direct link to the full gazette can be found at http://www.uspto.gov/web/trademarks/tmog/20110125_OG.pdf#page=1

The First Post of the New Year .. Happenings and Tech Stuff

Filed Under (Dorky Stuff, House, Random Thoughts, Various) by admin on 10-01-2011

 In what I am sure will turn out as the first post of many for the year 2011 I figured it would be good to say hi to the Interweb for a change.  Things have been kinda slow for the most part.  There are a number of projects I anticipate working on at the house and many surprises which I’m sure will crop up.  A couple of those will involve replacing the front door and also trying to landscape the front corner of the property.  With winter comes crappy outdoor conditions for any of these projects so the springtime cannot come soon enough.  The new truck is running great and it’s actually going to need its first oil change pretty soon.  Replacing the exhaust system with a new one by Magnaflow will be one of the first mods.  I am hoping to head to Puerto Rico this spring or summer with Vanessa.  It’s her hometown after all.  Having my own kick-arse tour guide will be supa-sweet.  High five.  Cats are good and are fatter than ever which is a good thing although I get woken up like clock work every morning by Hope who gets cranky and needs food.  Vazoom is rolling along pretty well and I am hoping to receive my official trademark registration from the U.S. Patent Office in the upcoming month or two.

 
On an unrelated note I should mention about a cool tech product I recently purchased in order for one of my desktop computers on the 2nd floor of the house to obtain access to my Internet connection.  While wireless was indeed an option I chose instead to go with an Ethernet over Power product from Netgear.  These items have been on the market for a while however many people aren’t quite aware this technology exists.  I chose to go this route because I’m a super try everything nerd.  The concept is quite simple – why not utilize your existing in house electrical lines / outlets as a way to connect computers together or to your home router?   Just plug in the first  adaptor into an outlet around  where the computer resides you are hoping to get on the Internet.  Plug an Ethernet cable from the unit to the computer.  Take the second unit and plug it into an outlet around the location of your home router/modem running an Ethernet cable from the new adaptor to an open port on the back of the router.  If your router or modem has no additional ports you will require the use of a small switch.  Depending on the distance and quality of the cable you should be able to achieve excellent results with speeds above 80Mbps.  Although my tests found that both Netgear adaptors could be placed into a surge protector and communicate, more stable results were obtained when the units were plugged directly into the wall outlets.   The units I purchased were the Netgear Powerline AV 200 ones pictured below.  **Make sure you purchase a kit..You need two physical boxes**.  I found a great deal for re-certified units on NewEgg for about $30 / piece.
