All computers getting same GUID after RIS

[Kyle]

I have a room fo 20 computers that when RIS'd they all have the same GUID. I get tot he last one or two and they wont RIS at all saying it can't fine the PXE bootfilename.

 

At the moment i am more concerend witht he duplicate GUID's. I tried the latest BIOS update on one PC and it seems to have made no dofference.

 

I have checked old posts and can'r find uch on it apart forma floppy bot disk that changes the UUID but these machines in question don't have floppy drives.

 

I have checked other machins that i have RIS and they are fine so i know there is no troublw with RIS. I have since found another 16 PC's on the domain with the same problem. I have also found out that all the Mobos in these PC's ar ASRock.

 

 

Can anyone help me please?

Have you set the guid in the PC properties?

I.E. Did you prestage the PCs in AD before RISing them?

[Kyle]

NO, the old account of the PC's in question (RIS in AD by OLD NM) were deleted from AD before i attempted re-RIS them. I did not pr-stage them at all.

Will taht work if the issue is with the mobo/hardware?

I agree with binky and here is the link:

I've tried it but it seems to make no difference to the GUID number on the Remote Install tab in the properties of the machine in AD?

..these machines in question don't have floppy drives...

 

I have 2 USB Floppys for this very reason it works a treat. They are under a £10 i think as well.
