[Xymon] monitoring Domain Controllers

[Root, Paul T]

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.

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...
