Getting duplicate error message when using RIS

Ive been trying to load an image onto a new laptop in the office here ...
but each time I start up the laptop and press F12 and load from PXE and enter a username and password error message appears...

" The server "Ris server" has detected duplicate GUIDs in the directory services. The duplicate existing machine names are :

Please contact your administrator to fix this problem.

Ive tried to load images to other systems and get the same error message

I would greatly appreciate it if any one xcould help with this....

You have a computer in Active Directory with the same GUID, possibly because it was imaged in the past and wasn't removed from AD.

You just need to confirm that the existing machine name in AD that is references really doesn't exist anymore and then just delete it.

Then you can image the machine.

To overcome this error I went into AD and located the server RIS is on ...right clicked it and into properties remote install..advanced settings ...custom and then set a name for the PC i was installing.....

TheCleanerCommented:'ll need to set those settings for RIS...That's part of the "initial setup" basically.

It should set something like "Imaged01, Imaged02, Imaged..n" so that each one has a unique name until you rename them yourself.

Or you'll need to customize RIS and the .inf files to create the computer names for you.
