Sounds like the kinda loaded questions I like to ask to see Shocter's brain frizzle and his eye twitch.   

It depends what you are using the server for.  Ex: if you are using it to do DHCP then you do not want to disable that service.  Try looking a few up and seeing if they relate to something you are or are not trying to accomplish.

So i installed server 08 on our server and it runs great. I was wondering if anyone knew what services i could disable to maybe help the server run alittle bit better?

And I subscribe to if it working don't eff with it.  So...if it "runs" great....
