I hear you I'm all for scripting; manually rdp'ing so many machines is a pain (I've 450ish active machines that I worry about, and if I sure wouldn't manually change something on all of them either).
If it is the services, you can effectively create a batch and iterate a list in a text file if you want. So long as your user account has administrative access on the machines, you can simply execute an
sc MyServerName config ServiceName type=demand
I think it would be. So you likely have a list of all the machine name/ips available, you can create a text file and iterate that. My batch skills are always rusty until I need to use them so I can't write that up for you atm, but the idea would be simply:
# your servernames (I've always wanted server names based on virus' :)):
And then when you iterate the read of the file, you'd have a call similar to
sc !a! config SERVICENAME type= demand
