How destructive is sysprep to the original machine

I would like to use sysprep to duplicate a virtual machine (server 2003) that I have running in Hyper-V.

The machine has quite a lot of configuration including IIS etc. It is currently called (Dev01), I would like to make a copy of it calling it (Dev02) but I need to ensure the Dev01 virtual machine is completely intact and not destroyed in anyway.

If I run sysprep, will this cause a problem or rephrased, what do I expect to happen to Dev01 once I run Sysprep.

Why would you run sysprep on Dev01?  

If you want to create a new machine from the Dev01 server, clone it, sysprep the clone and that would be that

Basically, sysprep takes out any identifying information like SID's, machine names ,and some machine settings.

Yes, while you are supposed to sysprep the original and then shutdown and copy, and then use that copy for all future VMs, I find it easier to just copy the VMs, and THEN run "newsid" on the copy once booted up.
thats just with XP or WIndows Server 2003, I'm sure with 2008 and Vista this no longer works but figured it may help.
