I am running Data Protection Manager 2007 on Windows Server 2008 (x64).  I have not been able to use the reporting piece, and haven't been running DPM long enough to wonder much about it, but when I went to finally figure it out the answer was rather simple.  If you want to fix it, the answer is here, but for more about what the problem is, you can go to the forum post below.

This problem occurs because of a new permission requirement in IIS 7.0. This
permission requirement is for ISAPI extensions that use a wildcard (*) script
mapping.

To work around this problem, follow these steps:
1. Click Start, click Run, type inetmgr, and then click OK.
2. In Internet Information Services (IIS) Manager, expand Web Sites, expand
Default Web Site, and then click the virtual directory for the report server.
3. Under Features View, double-click Handler Mappings.
4. Under Actions, click Edit Feature Permissions.
5. Click to select the Scripts check box, and then click OK.

How to fix--- Data Protection Manager error 3013  SQL reporting tab  ? in Data Protection Manager

I was going to extend a volume on one of my Server 2008 Core machines, and it told me "there is not enough space to perform this action"...

There was however enough space, but for some reason Microsoft Forefront decided that I shouldn't be allowed to extend a volume remotely.   So I disabled the services and did it anyway.

I was looking up how to set the IP address for Server Core:

Server Core: Setting a Static IP address

Server Core: Setting a Static IP address - Techinical Blog of Jay-R Barrios

I asked a coworker to find the method/command to run updates on Server Core and he came back with a link to this nice little script:

And every time I forget the command to do something in Server Core, when I do a search to find it, I always come back with a link to this post:

http://blogs.dirteam.com/blogs/sanderberkouwer/archive/2007/08/13/changing-server-core-s-look-and-feel-part-1.aspx

And just because I am lazy, and don't particularly like the command line (even though I like Server Core), I have created a folder with a few batch files that I use when I am setting up a Server Core machine.  For instance, I have a batch file that has the product key in it already and I run it to install the product key and activate. 

We are currently considering moving one of our DHCP servers to a VM on Hyper-V.  I was looking for something else and saw this thread on the TechNet Forums, and I want to keep it for later reference:

Add or remove programs

Again there are two ways to get information on the software that is installed onto your Server Core installation in absence of the "Add or Remove programs" Control Panel applet. (also known as appwiz.cpl)

Registry

The first way is by checking the registry keys underneath the following key:

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Uninstall

Luckily Server Core offers regedit.exe and regedt32.exe to digg deep into the registry of our Server Core box. Actually the "Add or Remove programs" Control Panel applet checks these registry keys at well. Since we all know how long it takes to get a complete list of all the software on your windows box it's obvious this method takes a lot of time.

As this TechNet page points out the software packages that are listed underneath the Uninstall registry key all have a registry value associated with the UninstallString. You can use this value as a command to uninstall the software.

I have come across a few articles that talk about how Server 2008 is what Vista hoped to be.  Here is an article that a Microsoft person wrote about it:

The Way I See It : Using Windows Server 2008 as a SUPER workstation OS

Also, this article talks about some performance testing:

Windows "Workstation" 2008 - Vista Done Right?

And if you want to run Hyper-V on your laptop, you may want to see this article about how to get the Wireless to be available to the VMs:

To change the time zone on a computer running a Server Core installation of Windows Server 2008, run control timedate.cpl.

In the past, I have used mstsc /console to get to "session 0" on remote machines.  With Vista and Windows Server 2008 that isn't the correct command though.  Instead it has been changed to mstsc /admin.
