Bug with PXE booting pre-staged machines for deployment returns event 519
There is a bug in Windows Deployment Services (WDS) in Windows Server 2008 R2 which prevents your pre-staged computers from booting via PXE. In the Event logs on the WDS server you can find event 519 stating that there are duplicate machines with the same GUID or MAC address, even though this is not true. There is a hotfix for this problem which is available from http://support.microsoft.com/kb/2028840/en-us.
