We have been testing out migrations from several domains into our main domain and discovered the following issue when we would go to migrate computer accounts:
ERR3:7075 Failed to change domain affiliation, hr=800704f1 The system detected a possible attempt to compromise security. Please ensure that you can contact the server that authenticated you.
This error does not impact moving groups or users. During our search for the resolution we found a lot of people saying you should use the KB article 942564: (http://support.microsoft.com/kb/942564) to resolve the issue by adjusting the cryptography algorithms to becompatible with Windows NT 4.0.
Looking deeper into that solution we decided that all we where really doing was lowering the level of security on our domain and we wanted to avoid that.
Fortunatly we read a little further down and discovered the KB article 944043 (http://support.microsoft.com/kb/944043/) which talks about the domain having 2008 Read Only Domain Controllers which we do not have so I overlooked that solution.
Further research showed that the KB 944043 should be used any time your domain is PREPARED for a 2008 RODC. The solution was presented here: http://blogs.technet.com/askds/archive/2009/10/19/admt-rodc-s-and-error-800704f1.aspx
So if you want to keep your 2008 domain at a higher level of security and bring in those computers from another domain check out KB 944043, grab those patches and see if it resolves the issue for you!

Windows 7 Beta
The Windows 7 Beta has been released to the public, it weighs in at 2.44 GB and is downloading as we speak. You can get your hands on a copy at: http://technet.microsoft.com/en-us/evalcenter/dd353205.aspx
Dell's "temprature probe has exceeded a non-critical threshold" message
Today I got a call from a user who was receiving a message that read:
"A temperature probe has exceeded a non-critical threshold..."
This message, according to Dell means that either the heat sink [on the CPU] has come loose or a fan is not working correctly.
This issue might be easy to resolve for many users by simply blowing into the fan vents, this could dislodge any dirt that is blocking the fan, which is the most likely issue. If not, you may need to remove the cover and use a can of compressed air or a PC vac to clean out the inside of the computer (remember to unplug the system first!).
If it is a heat sink, you can reattach it with some glue from a PC parts store.
Running the Dell diagnostics will help you to determine which part is not working correctly and lead you to the next step you should take (either cleaning or replacing the fan or fixing the heat sink).

Finding the brains of a computer.
In today's society we tend to try and humanize everything. We gave the tin man a heart because we were afraid of a robot without compassion, we assign human emotions to our pets, and we have even given the computer "a brain!"
If you read articles or books that are an introduction to computing you will commonly find a reference to the CPU as the brains of a computer; but is this really a valid comparison?
If we think about what the brain does, even one inside an ant, it is able to receive data, store that data, determine the best course of action based on previous data (or make an assumption or "best guess" when there is no previous data) and set about the body to perform the needed action. The brain handles so many different functions that we do not even understand how it really works (which is the reason we have so many different medications for emotional and mental problems).
The CPU on the other hand, does one thing and does it well. It performs calculations on information and returns that to the software that requested the CPU get involved.
Now there is no doubt that the CPU does emulate one of the thousands of functions the brain does, hell, the CPU is usually a lot faster than the brain at this one specific task; but that is it. The CPU simply cannot do everything the brain does.
On the other hand, the entire PC does perform most of the functions that the brain does from storing information in short term (RAM) and long term (hard drive) memory to receiving input signals (5 senses vs. keyboard, scanner, mouse, etc) and returning output (vocal or body language vs. monitor, printer, etc).
Even in computers running artificial intelligence software it is the software that emulates thinking not the CPU, still this software is governed by a very simple set of rules while the brain allows us to bend or break the rules that have been applied to us the computer will most often obey the laws it has been given. (If we ignore Chaos theory and errors, the computer will always obey). Three Laws Safe!
The day the CPU becomes the brains of the computer is probably the last day any of us want to see given the results of 2001, Terminator, or I Robot. Until that day the only brain that we will find involved with a computer is the one stored comfortably between the ears of the person at the keyboard!

Log Me In!
One of the greatest little tools out there is the ability to access remote desktops via the Internet. There are several programs out there that can do this such as Gotomypc.com and VNC. One of my favorites is logmein.com. Why is it my favorite? It uses codes that the remote desktop user must provide for remote access and it is free! VNC is great too, but it can be accessed by anyone if it is on and they know the password. Using logmein.com can be a secure way to get where you need to be (assuming someone is on the other end).
Perfect for those IT people who's moms keep calling for help!

Today I must post!
According to my calendar it says that Wednesday is the day I should post to this blog, now I've been ignoring that for a long time, but figured I'd get this out there and pick on Microsoft a little bit...
We decided that we needed to move from Lotus Domino to Microsoft Exchange, I guess we can save a little money that way (and the iphone the CIO just got only syncs with Outlook).
Anyway, while following Microsoft's excellent instructions (which you can find all over the Internet) to connect Domino and Exchange together so that people on both sides can look up the calendars of the others and the mail users are synced between the two systems.
The mail routes through SMTP so there is no longer a connector there. Which solves some of the horrors of the migration.
Anyway, after following the steps to the letter we were able to sync the users but along the way we had to fight through issues involving security settings. Those are easily solved by checking the event log, so no big deal.
The snag we hit was when we tried to get the calendar to sync. It was easy enough to get the Exchange server to see the Domino side but the Domino side just refused to look into the Exchange world. There were no errors being displayed anywhere and the Internet didn't offer any suggestions. I knew it I called Microsoft they would send me to Lotus and if I called Lotus they would send me to Microsoft so I was stuck in the middle of this mess.
It wasn't until I finally found a person on the Internet that had the very same issue and this has driven me to post the same information for others to find (if they are unlucky enough to have the same issue).
On the Domino server that you set up to do the calendar sync you have to install a program called the Exchange Calendar Connector. This runs as a task on the Domino server and according to Exchange the command is:
load excalcon Exchange
While the command you should use is:
load excalcon
If you follow the Microsoft instructions it will be:
load excalcon ExchFreeBusy
Once you do that, the systems should sync up and you can see the busy times on either side.
This does not allow you to see the details of the calendar though, that is only accomplished by people on Domino accessing Domino calendars and Exchange users accessing Exchange calendars.

Syncronize Contacts in Lotus Notes 8
For the longest time we have been trying to figure out how to get the word "disabled" to go away on the replication page in Lotus Notes 8 for the contacts to sync between the web access and the local file.
We found the issue today...
Under File -> Preferences -> Contacts there is a settings that reads Enable "Synchroize Contacts" on the Replicator that needs to be enabled. We found that setting several weeks ago and enabled it yet the system still said "disabled" on the replication tab.
So today we found the same setting (thanks to notes.net) under the More -> Preferences button in the Contacts database. That setting also has to be checked. It seems that there is a bug in the two linking up.
Anyway, once we checked both the disabled disappeared from the replication tab and the contacts synced up.
So there ya go!

Download your favorite Youtube!
An online service at http://www.vixy.net allows you to download any video on YouTube. You simply need to enter the URL of the video page into the Vixy service, tell it what kind of file you would like and then send it on its way.
Although this process has worked well in tests for me there is one side effect that I have noticed. Files downloaded to an mp3 format result in the file thinking it is 30+ minutes long. The good news is it plays correctly in iTunes and Windows Media Player so no worries!
So check the site out.

Screenshot How To!
Hello again trusty Internet users!
I asked a someone to send me a screenshot the other day and they said "How do I do that?" So I told them. After I told them they said "How do I do that?" So I told them again.
Here is a handy guide on how to take screenshots:
The first and only step in taking a screenshot is to press the "Prnt Scrn" or Print Screen button on your PC. Taking a screenshot on a Mac is quite different and I am sure Googling "Mac screenshot" will be of great use!
After you have pressed the "Prnt Scrn" button an image of what your screen looks like will be stored in Window's clipboard ready to be pasted into any application that will accept it. These applications can include Microsoft Paint (from your start menu --> Accessories) or Microsoft Word.
My favorite is Microsoft Word because I can quickly type in a some notes and details and send them to just about anyone. So, to paste your image into Microsoft Word follow these steps:
Open Microsoft Word
Click Edit
Click Paste
If you do not want to click Edit then Paste you can press "Ctrl-V" on your keyboard and be done with it.
This will paste the contents of the clipboard (which should be the image of your screen) into Microsoft Word.
"Advanced Screenshot"
You can take a screenshot of just the application you are working in by using the "Alt-Prnt Scrn" combination of keys. This will store an image of just the program that you are in. For example, if you have an error message on your screen you can click on that message and then press the "Alt" and "Prnt Scrn" keys to capture just that error window in the screenshot.
There are also plenty of free programs out there to assist you in taking even more "advanced" screenshots such as Screenhunter or to capture video of your desktop you can use FRAPS or Quick Screen Recorder.

Online Drives
If you are like me and you know that you are, you have a lot of pictures, music, and other data stored on your computer.
What if that computer is stolen or the hard drive crashes? Don't think it will happen to you? Well, one day it will so it is best to be prepared!
There are several things you can do to protect your data but possibly the easiest and cheapest way is to get yourself some online storage.
Companies like iDrive (http://www.idrive.com) and xDrive (http://www.xdrive.com) offer online storage. xDrive offers a free 5gb service and while iDrive does offer a free 2gb service their best offer is the unlimited storage for fifty dollars a month.
Online storage gives you a lot of options in protecting your data. Everything from manually copying files to automated backup. The disadvantage of the online backup? It is online! Someone might get into your files. If this is a concern you can always get an external hard drive and attach it to your computer or your network.
An external drive attached to your network can give you several hundred gigs of storage that is accessible from multiple computers.
The key here is making sure you have a way to backup and protect your data. When your iTunes music is gone... its gone!

Adding flash to your Blogger page
I spent some time looking around for ways to add flash to your blogger site and all of the ways I saw didn't really work out for me so I found this handly little work around using iframes.
You can enter this code:
{iframe src="http://wwwyoursite.com/pagewithyourflashmovie.html" frameborder="0" width="400" height="120"}Your browser doesn't support iframes, get your act together!{/iframe}
(Change { to < and } to >)
This requires that you:
1) Have an html page that has the code for your flash movie on it
2) Have the html page and your flash movie stored somplace on the Internet
3) That you change the info above to fit your movie size and name
Here is an example:
