Not quite answering your question, but: rather than testing those on the 
client, you could also consider a server-side test - e.g. a good way to 
check on a DNS server is to send a DNS query and check the response. You 
can do that just by adding the "dns" flag in hosts.cfg

Or to test a DHCP server, send a DHCP request to it - here's a script 
that uses the dhcping (sic) tool to do that:

A functioning DC ought to respond to ldap queries, so...
