Why use sysprep for Sharepoint 2010 Developer VMs? -

-

i have read several articles creating sharepoint developer vm. "sysprep" them. why (exactly) must sysprep done? kind of problems (and why) run if don't sysprep them?

(i suppose asking is, difference in doing "sysprep" , bringing vm, changing name/ip, reboot install sp?)

i've had success in past copying hyper-v vhd's method of cloning vm's - however, use sysprep when cloning of machines it's been mentioned best practice in many places. and, nice things allowing cleaning bunch of stuff don't want duplicate , letting me choose new name machine on boot. ms sysprep technical reference:

sysprep prepares computer disk imaging or delivery customer configuring computer create new computer security identifier (sid) when computer restarted. in addition, sysprep cleans user- , computer-specific settings , data must not copied destination computer.

and may want read russinovich's post on the machine sid duplication myth (and why sysprep matters) more explanation of how sids work , last paragraph has reason going route:

note sysprep resets other machine-specific state that, if duplicated, can cause problems applications windows server update services (wsus), microsoft’s support policy still require cloned systems made unique sysprep.

good luck!
