I've been struggeling for a few days to install BOINC silently to multiple machines in my office. It proved to be a minor problem I was facing and it's solved now.
If you follow the link to mycrofth's post, and go to the discussion, you will be able to automatically deploy BOINC onto several machines. Even I could do it! With a little help of member "The Lazy Slug" of course.
The explanation is for Windows SBS 2003. I don't know if Windows Server 2000/2003 is very different from this.

I have a few computer labs that have identical images. Can I include this in an image and have it work on all machines or do I need to change the agent name on each machine?

If you use the UD Agent, register it with the WCG servers and then do your imaging thing, you'll find you'll have to reregister each workstation individually. (Even using identical specification workstaions with the same computer name, etc will cause a problem after a few days.)

BOINC does have the edge over the UD Agent when it comes to deployment as providing you don't let it run, it will automatically register as lawrencehardin has pointed out.

In your case I would suggest that you install BOINC on your 'image' machine as a service, join the WCG, stop BOINC, delete all of the work sub folders in the BOINC directory and all of the XML files EXCEPT for account_www.worldcommunitygrid.org.xml and then create the image.

Hope that helps
