So a little background.  After a power failure and realizing that my DNS server for my ESX/vSphere cluster was a virtual machine and that VMware ESX clusters and a lack of DNS don’t work well I decided to add to move DNS to a physical server in my environment. I loaded the DNS server on Windows 2008 SP1 and added a secondary IP address for the DNS server the ESX hosts were already using to that W2K8 server.  This server was already my VMware vCenter server and I didn’t want to change the IP address for the whole server.

So a few weeks go by and one of my ESX hosts is showing disconnected.  Reconnecting it or trying to add it as a new host don’t succeed and in looking at the error logs on my ESX host I see that the request to the host from the vCenter server is coming from the secondary IP address I added to the vCenter/DNS server…hmmmmm….

So I double-checked everything and even tried looking at the routes setup on the Windows 2008 server but to no avail I can’t change the source IP address it is using.  After much searching around the web I found an article from Microsoft saying that they changed the way source IP’s are selected between Windows 2003 and 2008….no kidding….lol

Basically Windows using the IP source address “closest” to the destination address, oh goody…

Well hang on, here’s the solution.  Update to Windows 2008 SP2 then download the hotfix in the below article and install it, reboot, remove the secondary IP address then add it using netsh as documented in the KB article.  Note…there is no hotfix for Windows 2008 R2….great…not

Hope this helps someone and if you’re using more than 1 IP address on a Windows 2008+ host you should definitely be aware of this behavior/feature…. cough cough.  I love Microsoft most of the time but this one was a pain to find.

Problem Steps Recorder

If you are a Windows 7 or Windows Server 2008 user then this utility might be useful to you.  Problem steps recorder allows you record the activities leading up to a problem, then save that to a mht file that you can send to support.  If you have an error on an IIS application (yellow screen) then it will even copy all that information out as text and put it as part of the capture.  I like this utility because it’s easy for the user and useful for support…in fact I’m not only a fan, I’m a user of it!

As if you needed another reason

But if you do need another reason to not allow users to be Administrators on their PC’s here is another study that shows a vast majority of the security flaws for Windows or Office have no effect if the user isn’t an Administrator on their PC.

How To Avoid the Windows MBR Disk 2TB Limit by Using GPT Type Disks

If you want to use a disk larger than 2TB within Windows, it might look like you can’t use all of the space. This is due to the type of initialization performed on the disk. This lesson will show you how to initialize the disk with the "GPT" type of disk (rather than the default MBR type) so you can use disks larger than 2TB.

The 2TB Size Disk Limit Problem

Our screenshot shows you that when adding a very large disk to Windows, it looks like you can only use 2TB of that disk.

The GPT Solution

In order to use the full size, right click on the disk (1) and choose "Convert to GPT Disk" (2).

Now you have all of the space available to format (in our example, 10TB).

Creating the Partition

Now you just create the partition just like any other disk by right clicking on the unallocated space and choose "New Partition".

Notice the note when creating the new partition (circled in red on the screenshot).

Once you go through the rest of the New Partition wizard and choose to format it, the disk will be available as shown.
