Hi, Recently, I inherited some Windows machines. Including a pair of Domain controllers.
I'm wondering what 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. Then I see ADWS, the active director. Each machine has it as starting automatically, but only one is running. I assume that's correct, and that they watch each other so only one is running, right?
Is there a way to do a combo test to make sure it is running on only one?
Thanks, Paul.

NTDS is the core AD service, ADWS is only web services to allow connectivity to AD using http/https. All 12 of our DC's have them running at the same time.

Thanks, I’m obviously not a Windows guy.
Paul.

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
http://xymon.sourceforge.net/xymon/help/manpages/man5/hosts.cfg.5.html#lbAP
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...

That's not a bad idea.
Unfortunately, there is work to do there.
I created the DNS domain originally, and then another group got on "my" network and did windows. Then another group got on and used the domain.
The first group pulled out, after building up their own network, but the Windows Domain is still needed.
The first group never integrated the Windows DNS with the real DNS domain in the corporation. Somehow, I have to do that.
