Software

Anyone know of any software/application which can be installed on a small home network (5 PC’s) that will allow me to control services/settings on all of them from one place… No need for server. The following things I’d like to control would be the following:

– custom windows login legal message/disclaimer
– install apps
– control settings

Any ideas? Preferably free/open source… If pay ware is the only option then perhaps I’d buy it if it was under $100.
