During an upgrade of a DPM 2007 installation to DPM 2010 Beta I came across a Hyper-V core server with a DPM agent that would not upgrade. So the DPM agent had to be manually removed from the machine. As the Server Core does not have a graphical interface to remove programs this has to be done from the command line.
In order to remove a DPM 2007 agent from a server core:
For a 64 bit machine the following command:
Msiexec /x {72BF00D8-53E0-1539-F523-4347082BCC11} /qn /norestart
For a 32 bit machine the following command:
Msiexec /x {07CCDE6A-1D92-2C9C-D091-9E682643ABCC} /qn /norestart
You can restart the machine after this.
