Hi,

Recently, I inherited some Windows machines. Including a pair of Domain controllers.

I’m wonderingwhat are somethings I’m going to want to monitor to make sure these things keep running?

I have the Powershell client installed no problem.

I see DNS and DHCP services, and am adding those. 

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...
