One or more prerequisites for protecting this data source is missing – Windows 2003 & DPM System State Backups

If you want to protect a Server running Windows 2003 SP2 or SBS you need to ensure that the correct KB is applied as you will get the following error when trying to select a source.

One or more prerequisites for protecting this data source is missing.
Ensure that the following prerequisite software is installed on server and/or all nodes in the cluster:
Windows Server 2003 SP1 with Knowledge Base article 940349 (http://go.microsoft.com/fwlink/?LinkId=99034)
– OR –
Windows Server 2008 (http://go.microsoft.com/fwlink/?LinkId=128812)

To fix this you need to download and install the KB940349. Once you apply this KB to your  Windows 2003 Server and have rebooted, DPM will then allow you to select a source.

Hope it helps.

Moving DHCP Database from SBS 2003 to Windows 2008 R2

Today i decided to move my DHCP from the old Small Business Server 2003 as their is no longer support for this version of  Windows and moving it to a newer OS will be better. The move was pretty straight forward, you can look at the link below, i successfully exported the DB, installed the DHCP role on Windows 2008 R2 and reimported the DB without any errors. All my reservations and leases were still in place.

I then unauthorized DHCP on SBS 2003 and removed the role. I then rebooted one of my notebooks and let it renew its IP, that was successful as well. Hope it helps anybody else who is trying to move roles.
